8. Berchemia annamensis Pitard in Lecomte, Fl Gen, Indo-Chine, I. 925 (1912). 



Annam. 



Judging from the description this species may bear some relations to B. cine- 

 roscens Blume. Both species have rather broad leaves. The flowers of B. anna- 

 mensis are unknown; the fruit has been described as obovate, " haut de 10-12 mm. 

 large au sommet de 4-5 mm. k sa base de 2 mm." 



9. Berchemia pycnantha Schneider. See p. 215. 



10. Berchemia kulingensis Schneider. See p. 216. 



11. Berchemia formosana Schneider, n. sp. 

 Frutex scandens; ramuli ab initio glabri, violacei v. fuscescentes, rotundi; 



gemmae stipulaeque normales. Polia papyracea, ovata v. late ovata, glabra, basi 

 rotunda, apice plus minusve acuta, 2-3.5 cm. longa et 1-2 cm. lata, supra in sicco 

 nigrescentia, subtus albescentia pruinosa, nervis utrinque 6-8; petioli 7-9 mm. 

 longi, glabri. Inflorescentia pseudo-racemosa, in apice ramulorum lateraUum 4r- 

 8 cm. longorum terminaUs, 2-4 cm. longa; flores 2-3 conferti, glabri; alabastra 

 globosa, breviter apiculata; pedicelli floribus subbreviores ; sepala satis juvenilia 

 ovata, apice subito in acumen breve contracta; petala obovalia, sepalis breviora; 

 ovaria discum distincte superantia. Fructus nondum maturus, circiter 7 mm. 

 longus, 2.5 mm. crassus, versus apicem attenuatus, basi disco brevissimo cinctus, 

 pedicellis 2 mm. longis. 



Formosa: Tamsui, R. Oldham (No. 70). 



I cannot unite this form with any other species; it may be distinguished by the 

 characters given in the key. 



12. Berchemia yunnanensis Franchet. See p. 216. 



13. Berchemia Elmeri Schneider, n. ap. 



Frutex; ramuli glabri, rotundi, in sicco omnino nigricantes; gemmae stipulaeque 

 ut videtur normales. Folia elUptica v. ovato-elliptica, utrinque rotunda v. apice 

 obtusa, mucronulata, nervis utrinque 8-10, supra viridia, subtus pallida, pruinosa 

 v. vix papillosa, 1.5-3 cm. longa, 0.7-1.8 cm. lata; petioli 6 mm. longi, glabri. 

 Inflorescentia in apice ramulorum lateralium terminalis, pseudo-racemosa v. anguste 

 paniculata, valde juvenilis tantum visa floribus nondum satis evolutis. 



Philippine Islands: Island of Mindanao, Todaya (Mt. Apo), district of 

 Davao, August 1909, A. D. E. Elmer (No. 11317), sub nomine B. philippinensis 

 Vidal distributa. 



The specimen is rather imperfect, but VidaPs description of B. philippinensis 

 differs in: ** ramis tomentosis . . . ., foUis .... subtus puberulis." Vidal 

 does not describe the flowers. The very young flower-buds of B. Elmeri are globose 

 and rather obtuse; in the small, short petioled leaves it resembles B. lineata De 

 CandoUe.

The pubescence of the branchlets, petioles and inflorescence and also the shape 

 and size of the leaves of this species seem to vary greatly. Probably such speci- 

 men aa Oldham's No. 69 from Formosa (anno 1864) represent a very small leaved
