23. Schefflera lanceolata, Ridl. 



Heptapleurum avene. King, Journ. Asiat. Soc. Bengal 

 Ixvii, part ii, p. 47, not of Miquel. 



This plant seems to be quite distinct from Miquel*s 

 species in its diff'erently shaped leaves and smaller flowers : 

 King's description is taken from the Singapore plant. The 

 leaves are mostly simple but when the plant grows suffi- 

 ciently large, it bears at the top trifoliate leaves. 



24. Schefflera capitellata, sp. nov. 



Epiphyte. The leaves 8-foliate, leaflets lanceolate acute 

 narrowed to the base ; nerves fine coriaceous puberulous 

 beneath 3-5 in. long, 1 in. wide, petioles 1 in. long petiole 

 7 in. long. Racemes scurfy tomentose 18 in. long pedun- 

 cles -5 in. long, heads -4 in. through. Bracts minute and 

 caducous (not seen) . Flowers pubescent 5-angled, truncate, 

 quite sessile. Petals connate in a cap. Stamens 6, purple.

 HiU at 2,500 ft. (Curtis). 



This plant has been confused with the much larger 

 H. cephalotes, Clarke, which occurs on sea cliffs and banks, 

 and has very much larger leaflets broadly oblong cuspidate 

 and much larger panicles and the leaves are not sub- 

 puberulous beneath. In a plant I got on Penang Hill the 

 leaflets are oblanceolate, broadest at the top. A plant 

 collected by Wray (1542) on Ulu Batang Padang at 4,900 

 ft., may be this but the specimen I have seen is too young 

 and Wray describes it as a large tree. 



25. Schefflera Klossii, sp. nov. 



A large climber. Branches pale shining, young parts 

 white, scurfy. Leaves petiole stout 2*5 in. long ; leaflets 

 5, elliptic abruptly acutely acuminate, base narrowed stiffly 

 coriaceous, midrib beneath prominent ; nerves 5 pairs 

 elevate quite glabrous, 7 in. long, 3 in. wide, basal ones 

 smaller with shorter petiolules, petiolule of terminal one 

 1 • 4 in. long. Basal bracts of inflorescence lanceolate acumi- 

 nate coriaceous scurfy narrow 1*5 in. long. Panicles 5 

 scurfy 9 in. long. Umbels simple, numerous, peduncles '25 

 in. long. Flowers small, pedicels '05 in. about 10, scurfy.
