A species apparently most closely allied to Strobilanthes debilis 
Hemsl. from which it is distinguished by its larger crenate 
leaves. ; 
RUBIACEAE 
LASIANTHUS HAINANENSIS sp. nov. 
Frutex 2 ad 3 m altus, petiolis junioribus stipulisque parcis- 
sime pubescentibus exceptis glaber; ramis teretibus, laevis, 
circiter 3 mm diametro, internodiis 6 ad 8 cm longis; foliis 
oblongis, olivaceis, nitidis, chartaceis, 12 ad 16 cm longis, 3.5 
ad 5 cm latis, -utrinque angustatis, basi acutis, apice tenuiter

rectis, anastomosantibus, nervis marginalis leviter arcuatis; 
petiolo 10 ad 12 mm longo; stipulis oblongis, pubescentibus, 
acuminatis, 2.5 mm longis; fructibus axillaribus, paucis, obo-

ravines, altitude about 1,400 meters.

In vegetative characters this species is very similar to Lasian- 
thus laevigatus Blume from which it is at once distinguished by 
its solitary or fascicled sessile fruits.

pubescentibus) ; foliis mebranaceis, olivaceis, ovatis ad oblongo- 
ovatis, 7 ad 11 cm longis, 3 ad 7 cm latis, glabris, olivaceis,

Ng Chi Leng, McClure 8588 (type), 8626, December 21, 1921. 
On rocks in forests and on burned-over slopes, altitude 600 to 
750 meters. 
Apparently well characterized by its glabrous, coarsely re- 
pand-toothed, ovate to oblong-ovate leaves, and its semihastate 
auriculate stipules or stipulelike appendages. The ultimate re- 
ticulations are not elongated, and contain numerous free veinlets.
