220 WILSON EXPEDITION TO CHINA 



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- 

 rascens 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."

11. Berchemia formosana Schneider, n. sp. 



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

 gemmae stipulaeque normales. Foha 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 lateralium 4- 

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

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

 ovata, apice subito in acumen breve contracta; petala obovaha^ 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 tliis form with any other species; it may be distinguished by the 

 characters given in the key. 



12. Berchemia yimnanensis Franchet. See p. 216. 



13. Berchemia Elmeri Schneider, n. sp. 



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

 ut videtur normales. FoUa 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; petioU 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 nomme B. philippinensis 

 Vidal distributa. 



The specimen is rather imperfect, but Vidal's description of B. philippinensis 

 differs in: " ramis tomentosis . . . ., foliis .... subtus puberulis." Vidal 

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

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

 Candolle.

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