Paluma Range Macaranga tanarius (male flowers) Westringia Wynyabbie Gem Acacia umbellata 22Myrtaceae Proteaceae Rubiaceae Leptospermum Pink Cascade Melaleuca Harkness Melaleuca sp. Miles Syzygium Cascade Syzygium wilsonii subsp. wilsonii Grevillea Bird Song (G. Honey Gem x G. banksii) Grevillea Coastal Sunset (G. banksii Red x G. Golden Lulu ) Grevillea Fire Sprite (G.venusta x G.longistyla) Grevillea Flamingo Grevillea Ivory Whip Grevillea Lana Maree Grevillea Little Honey Grevillea prasina (grafted) Grevillea Strawberry Sundae Atractocarpus fitzalanii Stephen brought a sample of yellowing leaves from his Buckinghamia celsissima (above). He asked the meeting for ideas of the likely cause of this appearance. It was suggested that his plant might be suffering an iron deficiency or phosphorous toxicity or lime chlorosis but, unfortunately, no certain solution was offered. Note from Keith:- This small Acacia specimen brought in by Steven is definitely Acacia umbellata. 4

5 Outing in October:- To the Rainforest section of the Palmetum It was bad luck that we chose to walk the rainforest at this particular time. Sadly we were greeted with a barricade and a notice pointing out that the presence of Flying Foxes was a danger to our health. We were not deterred but safely took ourselves to the left of the Rainforest and headed towards the river. We saw at least the following although John now has a more complete of list of all the Palmetum plants which is in the table below along with families and some common names. Some plants which I managed to list as we went along:- Aleurites moluccanus; Alstonia spectabilis; Argyrodendron trifoliolatum; Castanospermum australe; Dimorphocalyx australiensis; Diploglottis bernieana; Eleocarpus grandis; Ficus copiosa; Ficus drupacea; Grevillea baileyana; Lunasia amara; Melaleuca leucadendra; Nauclea orientalis; Phaleria clerodendron; Platyserium bifurcatum; Psilotum nudum; Syzygium cormiflorum; Syzygium wilsonii; Neolitsea dealbata. After a couple of hours we enjoyed some chat time at the Tumbetin lodge which was a pleasant end to the morning. Palmetum Lily some of you have already had this information but I had a space to fill. Keith spent quite a lot of time trying to identify this Lily which we all had wondered about when we saw it growing in the shade of a large tree at the palmetum. He made another trip back to it to check out various identifying features. 3+3 structure tiny corkscrew-like features fused stamen very tricky. Then finally Keith had a confirmation of one train of thought Commelinaceae family - -Cochleostema odoratissimum from Costa Rica, Panama and Nicaragua- definitely not native. Thanks Keith 5

8 COMMUNICATIONS NOVEMBER OUTING:- This month our outing will be to Cape Pallarenda Conservation Park at the end of the Pallarenda road, for a gentle walk round. We will meet at the far end of the car park at 9am. Bring your own morning tea, sun screen and mozzie repellent. SGAP NEEDS YOU Please think about what you can do to help our SGAP group particularly for the many activities we hope to hold in Members talk! Rex talks about Tecomanthe and mite images G day, just thought you might like to see these images. There are two pics of Tecomanthe hillii. I think I've spelt that right! This plant is growing up the pole of my verandah. Also I have one of Erinose mite damage we saw at Alligator Creek last month. According to David Hockings book Erinose mites are specific to a plant species. This one could well be a new record, I can't recall the name of the plant involved, Beth Bailment might recall it as she was the one who found it. JANE commented on some action in her garden: Poplar gums, Euc. platyphylla, are flowering at present and the flying foxes are having a ball in mine. They are dropping their leaves and branchlets and making a huge amount of litter/mulch. Also, as she discovered today when she looked, Milettia pinnata, (formerly Pongamia pinnata) is flowering and no doubt will have finished by the time of next meeting. 8

9 Plant of the month by John Elliott Alloxylon flammeum (F. Muell.) P. H. Weston & Crisp Pink Silky Oak, Satin Silky Oak, Queensland Waratah A large Australian tree (to 36 m) found only on the Atherton Tablelands in tropical upland rainforest between m. A glorious red flowering tree of the Proteaceae family, this species was only described in 1991, having been previously known as Oreocallis wickhamii. To begin at the beginning. Throughout the latter half of the 19 th century, Ferdinand von Mueller described many new species, which were forwarded to him by various agents as they explored the newly colonised further reaches of northern Queensland. One such was Walter Hill, now remembered as the Superintendent of the Brisbane Botanic Gardens in 1855, and first Colonial Botanist of Queensland Walter also undertook several expeditions to Cape York and along the north Queensland coast and, in 1873, climbed Bellenden-Ker where he collected specimens of a Proteaceae tree, In monte Bellenden-Kerii, altitudine circiter 2500 pedum, ubi Heliciae Youngianae adsociatum; Walt. Hill. Mueller described this in 1874 as Embothrium wickhamii, in Fragmenta Phytographiae Australiae 8(66); 164 (tax. nov.). The genus name is from the Greek, en = in and bothrion = small pit, referring to the location of the anthers in small cavities within the calyx. The species name is for John Clements Wickham, Captain of the Beagle, which explored northern waters between In 1874 this name was revised by Mueller to Oreocallis wickhamii and remained unchanged until Oreocallis is from the Greek oreos = mountain and kallos = beauty, referring to the splendid flower show in mountain habitats. It is worth noting at this point that the genera Embothrium, Oreocallis, Alloxylon and Telopea are a small group of terminal red flowering plants that occur along the southern edges of the Pacific rim. They are known as the subtribe Embothriinae, which is an ancient group from the Cretaceous and which must have predated the splitting of Gondwana, some 60 million years ago. By the 1980 s there was a growing interest in the fact that Oreocallis wickhamii, contained in fact two species. Indeed, in Muellers collection there appeared to be two species, which had gone unnoticed as separate species, one of which had been collected at Trinity Bay in 1881, which is in lowland rainforest. This genera was then revised by Peter Weston and Mike Crisp, of the Royal Botanic Gardens Sydney, which led to the reallocation of one species as Alloxylon wickhamii, and the addition of a new species, Alloxyllon flammeum. Alloxylon from the Greek allo = other or strange, and xylon = wood, and refers to the unusual cell architecture compared with the related genus of Telopea and Oreocallis. RT Baker had first described this unusual wood structure in 1918, in his publication; On the Technology and Anatomy of some Silky Oak Timbers. The timber is very light with a specific gravity of 0.53 and has been marketed in Queensland as Satin Oak, STO, under the name of Oreocallis wickhamii. It has a typically silky oak appearance, with a pale pink colour, and a particular sheen, which adds to the ornamentation of the timber. 9

10 So A. flammeum had been misidentified as A. wickhamii since 1881 at least, although according to Weston & Crisp they are readily distinguished even with only vegetative material. A. flammeum can be distinguished by having hairy/ferruginous stems and petioles, whereas those of A.wickhamii are glabrous. The flowers of the former are much brighter and more numerous than the latter which can be almost light purple rather than bright red. From Elsewhere Website Fan Club :- This correspondence is worth retelling.. Hi, I am very fond of syzygium species and looking for the seeds of Syzygium papyraceum, Syzygium aqueum, Syzygium samaragense and Syzygium calcadense. Do you know the source to buy these seeds from? I'd be very grateful for any contact information. Best regards, Olga Sorry for the delay but I have been away looking at plants! I don t know of any supplier for these seeds. SGAP has a seed bank but I don t have a current list handy. I am sure I can find out if you wish. You don t say where you live but if it is Townsville you can collect the first two on your list without too much difficulty. S. aqueum grows in Anderson Gardens, and S papyraceum at Paluma village right by the road and I have collected seed there myself in December. I can give you the exact location if you wish? Best Wishes, John Elliott Hi John, thank you for the answer. I'm sorry I forgot to specify where I live. Unfortunately It's too far from Townsville. Russia, Siberia, to be exact). I grow syzygiums as home plants. I have S. jambos, S. paniculatum, S. rubicundum and S. malaccense (from seeds). The more I learn about syzygiums the more I get obsessed with these wonderful plants. Now I search for other species seeds in the Internet. The species I wrote about seem to be very attractive and give edible fruits. But I haven't managed to find where to buy them so far. I'll appreciate any useful information or link. Best regards, Olga 10
