    Australian native plants, CPs, getting out in the bush
  1. Hi all, Craig and I did another extended hike (27 days, 230 km) in the remote Kimberley of the NW of Australia last August. This time in NE Kimberley. It had been a large and late wet season so a lot of CPs were still in growth and flower. One thing that struck us was the enormous diversity in the form and colour of Drosera indica flowers. In contrast to our walk last year, most of the plants this year were green (no red to speak of) but the flowers made up for that. Here are a few. Standard pink form: A larger-petal fancier pink form: Standard orange form: A beautiful hybrid between pink and orange forms that we like to call "Kimberley Rose": A quite curious pink form with frilly petals and pink stigmas: A pale pink form with a flower looking more like a petiolaris complex sundew than an indica: Pure white version of the above: Cheers, Dan.
  2. Hi Greg, I just noticed you post (after several months it seems!). I think your call of B.rorida might be a good one. We saw this plant on the Mitchell Plateau (NW KImberley). CALM's Floarabase database has several occurrences of this plant in the vicinity. Unfortunately, the one plant we saw was not in seed at the time. btw. craig and i are angling to get up to the Kimberley again this year for another extended walk, so perhaps there might be some more photos to show in the coming months. cheers, Dan.
  3. Hi Iggy, I'm not too sure if it stays moist all year (i've only been up there in summer). The region gets much of it's rainfall in the summer as large thunderstorms, so I'd say the ground would be at least moist during the warmer months. During the winter the ground might dry out though. Cheers, Dan.
  4. Howdy all, Last week I visited by sister who lives in Brisbane (capital of Queensland). Just to the north of Brisbane are the Glasshouse Mountains (eroded volcanic plugs). Three fo around eight can be climbed without ropes. Mount Tibrogargan - a 250m vertical scramble for excellent views (took about 2 hours to get to the top). There are many marshy and heathy areas in this area that support a number of species of carnivores. D. spatulata growing in sandy soil on the edge of a forestry coupe. D. burmanii growing in a roadside drain. Rosette is ~5cm across. D. burmanii flower scape. D. burmanii and D. spatulata growing side by side in the same drain. U. uliginosa in a seep. Very similar flower to the form that grows around Yamba further south. U. uliginosa leaves. Enjoy! Cheers, Dan.
  5. Hi George, Altitude is around 700m Cheers, Dan.
  6. Hi Fernando, We hadn't properly exposed the tuber when I took the last shot (it's the same clod of dirt as the first shot, but we subsequently did a bit of cleaning up to expose the still-forming tuber - which is the white succulent-looking root-like thing). Cheers, Dan.
  7. Hi George, Here's a close up of a trap and some leaves. Not very good, but we should have someone available that can show you to the spot for a closer leaf examination on the weekend! Cheers, Dan.
  8. Howdy Sean, We only saw a half dozen flowers, and all seemed to be a similar colour to the one's posted. The flower shown next to the tuber is perhaps more representative of the true colour. Hopefully next year will be a better season for them and there'll be more to see... Cheers, Dan.
  9. Howdy all, Last weekend Ross Rowe showed Craig, Duncan and I a small patch of tuberous Utricularia dichotoma growing in the Canberra Nature Reserve north of Kambah. The habitat was a intermitantly moist (mainly winter and spring) soak that was almost dry at the time of the visit, but not as dry as the surrounding hillside. From left: Craig, me and Dunc in the soak where the dichotoma live. Despite having the wettest spring for 4 years there were few U.dichotoma to be seen, and those seen had rather small flowers. The plants are just starting to produce their tubers at the moment. U.dichotoma with tuber in centre (small leaf seen at the top of the tuber and spherical trap near middle). The flowers were quite interesting with the central ridge on the raised palette being far more prominent than the two at the side (the two side ones being typically prominent in my experience). Close-up of flower. It's not surprising that these things have adapted to be tuberous. In the summer the ground in the soak will be bone dry and concrete hard. This soak has probably been mainly dry for the last 4 years because of the drought we've just emerged from. Cheers, Dan.
  10. Hi Sean, Is there much variation in U. dichotoma across its range? I was just looking at the one, posted, the from with the yellow palate bulge from the same location, and one from a sub-alpine area of the ACT. U. dichotoma with yellow on palate bulge (Cranbourne VIC) U. dichotoma with creamy yellow on palete bulge (Orroral ACT). Looks like the variation is mainly in colouration and the width of the corolla, but the structure on the palate bulge varies a little also... Cheers, Dan.
  11. Hi njh, Actually, we were photographing plants for incorporation into the florabase database. They may have a lot of Stylidiacae in the database, but very few have accompanying images. only 3-4 of the Kimberley ones have images. http://florabase.calm.wa.gov.au/search/adv...t=&type=sum While a couple of our Kimblerley ones are common, most are not, and a couple may be new to science. With regards to Dougs book, the tropical Stylidium section (one page) aint all that helpful either. Juliet Wedge (WA CALM's stylidium expert) suggested a few publications for me to look up, but i've not had time as yet. Cheers, Dan.
  12. Hi Belinda, I once found a population that looked to be hybrids between the local D.peltata and D. auriculata (variably hirsture sepals and very poor seed set). To drag up some old images: http://members.optusnet.com.au/~emma_dan/C...rra_Sundews.htm It's so hard to tell if somethign is a hybrid because there's heaps of variation in these plants around Canberra (as the above URL attests - red forms growing next to green forms, white and pink petals also intermixed). As George says, the seed morphology could be indicative. In common with Sean, I've not seen flowers quite like yours on eastern Australian plants - very interesting. Cheers, Dan.
  13. Hi Fernando, >Well then, you'll have to go back and take more pictures! I hope to one day, but the access is somewhat tricky. Most of the photos I have shown were taken in the Prince Regent Nature Reserve. You need a permit to enter this reserve, and permits are only granted on the basis of a programme of scientific research (we were collecting for the WA herbarium and also doing a weed survey). There are no access tracks within the reserve, so everything is accessed on foot. Our trip involved being flown from Broome in to a small dirt airstrip that we had graded especially for us. This took us to the southern boundary of the reserve. We then walked >200 km over 25 days to the northern boudnary to Mitchell Plateau, where there is another airstrip that we were extracted from (tehre is also a popular 4WD track that ends at the Mitchell Plateau). Our only luxury was a food cache we had dropped in by helicopter half way along otu route. We didn't see a single other person for the entire 25 days! You might get the mistaken impression from my photos that the plants are thick on the ground and all in the one region, but they are in actuality spread out over our 200 km walk. They probably ARE all over the place int eh wet season, but are restricted to semi-permanent soaks in the dry. I have driven to the Mitchell Plateau on a previous trip (1997), but haven't seen the orange flowered indicas before this trip. The problem is that you can only drive in during the dry season and most of the carnivores are going dormant by then. You should eb able to see petiolaris complex plants along the roadside early in the dry though (early April say). >I'm curious to know how much it cost to travel to these locations, could >you please let us know? Lots! Broome has an international airport, and there is a domestic airport at Kununurra (these are the closest access points to the Kimberley). Kununurra is the location that Siggi found his new form of D. indica (hartmeyeroium?). You would have to hire a 4wd from either one of these spots and have a bit of a drive around (at AU$140/day or similar). The Gibb River Road is the main track through the Kimberley, and visits a number of pleasant gorges - a walk along any of these creeks early in the dry should turn up some plants. All that being said, for someone coming in cold to Australia, for my money I'd fly to Darwin in late summer (say early to mid February, or maybe march depending on how well the wet season goes). It's easy to get to (has an international airport), and there are a multitude of beautiful plants to see within a short distance (~30km fro the city centre). Unfortunately, most of Kakadu is inaccessible at that time - but the plants are all out. A couple of years ago I went in late January and found D. indica, darwinensis, petiolaris, dilatato-petiolaris, and burmanii. Also B. aquatica, and a number of utricularia (although these were just coming into flower - hence the suggestion to go a bit later). You probably wouldn't even need a 4WD to see a good variety of plants, although some ground clearance might help if you got adventurous. It's an 800 km drive to Kununurra from Darwin, and there'd be heaps to see along the roadside along the way at that time of year. Hope this helps. Cheers, Dan.
  14. Hi Fernando, The pale orange flowered form was in a different catchment to the bright orange and pink flowered plants (about 15 km away). There was a small tangled patch of them all out on their own, and they seemed to be a distinct gracile form (more like the forms you get in north eastern Australia - although I've never seen orange flowers over east). Unfortunately we didn't have time to collect a specimen for the herbarium, and I have posted the only photo I took. Knowing my luck it'll turn out to be a novel species! Cheers, Dan.
  15. Howdy, As requested here are some more habitat shots. The habitat of the large indicas. Small wet areas on a rocky platform marginal to a creek. Lots of utrics also. The habitat of the broad leaved petiolaris complex plants - open tropical savannah forest. We could see that in the north of our walk where it hadn't burnt and hadn't rained all the platns were completely dormant (and very hard to spot). In the above inage it'd rained and burnt, so the plants were pushing out new growth and flowering. The typical habitat of the narrow leafed petiolaris complex sundews. This one's a bit of a gloat - also a nice place for a refreshing swim and a shoulder massage under the cascades. And finally another picture for Fernando... We didn't see any evidence of hybrids between the pink and orange flowered forms of D.indica (perhaps they are infertile). An interesting finding at this particular site was that there was abundant seed in the orange flowered plants, but none on the pink flowered plants. The plants at the site were particularly robust and large. However there were more gracile forms around, and above I include an image of a pale orange flowered variety that grew nowhere near as large as the former orange flowered plants. Cheers, Dan.
