DR. O. STAPF ON THE FLORA OF MOUNT KINABALU. 167 
At 6000 feet (Haviland, 1190). 
Very remarkable from the long fibres into which the nerves of the stipules and bracts 
run out. Otherwise the plant approaches Begonia borneensis, A. DC., in the general 
habit and in the floral structure. 
 UMBELLIFER.E. 
HYDROCOTYLE JAVANICA, Thunb. Diss. ii. 415, t. 2. 
Bed of the Dahombang, alt. 3000 feet ( Haviland, 1273). 
Distribution: All over Malaya to the Philippines and Australia ; Indo-China to Hupeh 
and Ichang; Khasia, Himalaya; Ceylon and Malabar. 
According to Dr. Haviland, the plant is said to be used by the Dusuns like “ tuba,” 
for poisoning fish. 
The specimen referred to H. javanica in Fl. of Trop. Africa iii. 4 is hot that species. 
TRACHYMENE SANICUL&FOLIA, Stapf, in Hook. Ie. Pl. t. 2308. Perennis. Rhizoma pro- 
stratum vel ascendens, ramosum. Rami in individuis in rupium fissuris crescentibus 
valde abbreviati, dense foliorum residuis squamiformibus vestiti, sub ipsá facie rupium 
iteratim ramulosi, ramulis brevissimis densissime foliis vestitis et seapos umbelligeros 
edentibus; in individuis soli humidioris sepe valde elongati, in parte subter- 
raneá crebre radicantes, in parte supraterraneá e basi longe prostratá ascendentes, 
pedunculos ex axillis foliorum edentes, caulis badii patule rufo-hirsuti internodiis 
in plantà luxuriante ad 1 poll. longis vel longioribus. Folia petiolo glabro vel rufo- 
hirsuto 21-4 poll. longo suffulta, ambitu cordato-orbicularia, plerumque transverse 
latiora, ad 3 triloba, lobis obovato-cuneatis, aeute tridentatis vel in majoribus trilo- 
bulatis, lobulis tridentatis et dentibus interdum in latere exteriore denticulo auctis, 
4-12 lin. longa, 8-18 lin. lata, crassiuscula, glaberrima vel utrinque hirsuta. 
Pedunculi (vel scapi) teretes, nudi, 21-9 poll. longi, tenuiter striati, rubelli. Invo- 
lucri phylla linearia vel lanceolato-linearia acuta, 2-4 lin. longa, glaberrima vel 
hirsuta ciliataque. Pedicelli sub anthesi phyllis «equilongi, deinde paulo longiores, 
glabri vel parce hirsutuli. Calycis dentes persistentes, triangulares, distincti. 
Petala alba, obovata vel elliptica, 1-1} lin. longa, supra costulá medianá notata. 
Antherze roses, elliptieze. Styli demum deflexi, vix 4 lin. longi. Fructus a latere 
valde compressus, reniformis, 14-13 lin. longus, 13-27 lin. latus; mericarpia 
sequalia vel subzequalia, glaberrima, atropurpurea vel brunnea, exalata, jugis inter- 
mediis tenuissimis, marginibus interioribus approximatis, 
From 7000 feet to the top, in the higher region in crevices of the rock and very 
stunted (Low, Burbidge : Haviland, 1130, 1162). 
Nearest allied to T. humilis, Hook. fil., from the alpine and subalpine region of Victoria 
and Tasmania. The stunted, glabrous form agrees perfectly with T. humilis so far as its 
growth is concerned. The involucrum, the umbels, the flowers and fruits are, apart 
from the hairiness, exactly the same in both of the Kinabalu forms, and they differ hardly 
at all from those of T. humilis. Thus the main difference is in the shape of the leaves, 
and is rather considerable. The stunted and the creeping forms from Kinabalu look at
