408 Materials for a Flora of the Malayan Peninstila^ '. ^ 



The first author to put this plant into the genus Pterisanthes was 

 Korthals who (fide Miquel Aun. Mus. Lugd. Bat. I, 85), thus named 

 it in the Herbarium (at Leiden ? ). Miquel regarded Pteriaanthes as only 

 a section of Vitis. He had therefore to find a name for this plant in 

 that genus ; and, finding the name V. coriacea pre-oocupied by a species 

 of Gissus (DC. Prod. I, 632), he called this V. polita, Miq. 



Var. araneosa ; Leaves often ovate-oblong, always more or less 

 rufescent cobwebby beneath. Vitis araneosa, Miq. Ann. Mus, Lugd. 

 Bat. I, 94. Gissus araneosa, Miq. Fl. Ind. Bat. Suppl. 517.

 Mr. Wray in his field note oa this says " leaves with a shining 

 black line round the edge on the outer margin of which is a line of 

 warm brown hair, midrib beneath reddish." 



2. Pterisanthes cissoides, Blume Bijdr. 193. Stems glabrous, 

 striate. Leaves 8-foliolate ; the middle leaflet narrowly wedge-shaped^ 

 the two lateral more or less oblong, rounded on the outer side, straight 

 on the inner, all with a few obscure distant teeth in the upper half or 

 third, entire in the lower; both surfaces with deciduous arachnoid 

 hairs, glabrous when adult ; main nerves about 4 pairs, spreading ; 

 length 3 to 6 in., breadth 1"25 to 3 in., petioles 15 to 3*5 in. ; petiolules 

 of the middle leaflets twice as long as those of the lateral. Flattened 

 floriferous rachis of the inflorescence variously lobed, from 2 to 6 in. long 

 and less than half as broad, borne on tendril-bearing branches longer 

 than the leaves. Male flowers on slender pedicels -75 in. long, 4-merous. 

 Female flowers numerous. Fruit globose, '35 in. in diam., with coriaceous 

 epicarp and about 4 seeds. Miquel in Linnaea, XVIII, 385, t. VIII;

3. Pterisanthes heterantha, Laws, in Hook. fil. Fl. Br. Ind. I, 

 664. Stems cobwebby when young, ultimately glabrous. Leaves 3- 

 foliolate, rarely 5-foliolate, the middle leaflet more or less wedge-shaped 

 and usually broader than the obliquely ovate-oblong laterals, (sometimes 

 all three more or less oblanceolate), acute or shortly acuminate, 

 remotely glandular-dentate in the upper part ; upper surface glabrous 

 except the pubescent nerves ; the lower rusty -tomentose ; main nerves 

 of leaflets about 5 pairs, spreading, rather straight ; length 2 to 4'5 in. 

 breadth 8 to 2"5 in., petioles "8 to 1*5 in. Flattened rachis narrowly- 

 oblong, sinuate, acuminate, 3 to 5 in. long and *3 to "75 in. broad, borne
