ellipticis, utrinque acutis, 4 ad 6 cm longis, 1.5 ad 2.5 cm latis, 

 supra glabris, nitidis, subolivaceis, subtus pallidioribus, leviter 

 pubescentibus; nervis utrinque circiter 7, subtus conspicuis, 

 rubro-brunneis ; petiolo 5 ad 7 mm longo; racemis axillaribus 

 terminalibusque, usque ad 7 cm longis, leviter pubescentibus; 

 floribus albidis, pedicellis 4 mm longis, leviter hirsutis; sepalis 

 subliberis, glabris vel subglabris, oblongo-lanceolatis, 3 mm 

 longis, acutis; corolla 7 mm longa, subcylindrica, extus parce 

 hirsuta, lobis ovatis, subacutis, 1 mm longis; stylis 4 mm longis,

Ng Chi Leng, McClure 9380, May 1, 1922, in thickets in 

 moss-covered soil at the summit of the mountain, altitude about 

 1,900 meters. 



A species like Pieris villosa Hook. f. characterized by its 

 filaments being non-corniculate. In general aspect it resembles 

 P. ovalifolia D. Don, but differs not only in its staminal but 

 also in its vegetative characters. 



MYRSINACEAE 



MAESA ACUMINATISSIMA sp. nov. § Eumaesa. 



Frutex ut videtur scandens, glaber, prophyllis minutis, lanceo- 

 latis, haud cumbiformis; inflorescentiis terminalibus vel pseu- 

 do-terminalibus, bipinnnatin paniculatis, pyramidatis, 5 ad 7 cm 

 longis, sepalis glaberrimis, haud lineatis ; f oliis lanceolatis, mem- 

 branaceis, olivaceis, nitidis, glaberrimis, lineis nervilliformibus 

 destitutis, 9 ad 12 cm longis, 2 ad 3 cm latis, integris vel undu- 

 latis, basi acutis, apice caudato-acuminatis, nervis utrinque 4 

 vel 5, distinctis, curvato-anastomosantibus, petiolo circiter 1 cm 

 longo; paniculis e basi ramosis, ramis primariis paucis, patulis, 

 inferioribus usque ad 3 cm longis, pedicellis tenuibus, 5 mm 

 longis; fructibus subglobosis, circiter 3 mm diametro, haud 

 lineatis vel punctatis, sepalis persistentibus triangularibus, 

 acutis. 



Ng Chi Leng, McClure 8572, 9454 (type), in forested ravines, 

 altitude about 1,400 meters. 



A species perhaps belonging in the group with Maesa piso- 

 carpa Blume, but, if so, then radically different from the other 

 species placed here. Even if placed with those species char- 

 acterized by lateral inflorescences, it is apparently widely dif- 

 ferent from any hitherto described form. Among the species 

 with terminal inflorescences, the present one is characterized 

 by its relatively small panicles which do not exceed 7 cm in
