EUPHORBIACEAE. 



Determined by J. Hutchinson. 



ANDRACHNE L. 



Andrachne capillipes Hutchinson, n. comb. 



Andrachne cordifolia Hemsley in Jour. Linn. Soc. XXVI. 420 (non Miiller 



Arg.) (1894). 

 Flueggea capillipes Pax in Bot. Jahrb. XXIX. 427 (1900). 



Western Hupeh: Ichang, roadsides, alt. 500 m,, May 1907 (No. 

 3205; shrub 0.6-1 m.). Western Szech'uan: Nanch'uan, A. von 

 Rosthorn (Nos. 2250, 2253). 



A. capillipes is very similar in general appearance to A. cordifolia, Miill. Arg., 

 from India, but differs markedly in the female calyx which is much smaller in 

 our plant and not enlarged and foliaceous in the fruiting stage; the female pedi- 

 cels in tlie Indian plant are usually longer. 



Pax places this species in Flueggea which has apetalous flowers, but the examina- 

 tion of the flowers of von Rosthorn's Nos. 2250 and 2253 shows the presence of oblong 

 petals about half as long as the sepals. The latter are in the pistillate flower some- 

 times, but not always, acute or mucronulate. Von Ptosthorn's specimens agree per- 

 fectly with those collected by Wilson, and there can be no doubt of their identity. 



Andrachne capillipes, var. pubescens Hutchinson, n. var. 



A typo recedit foliis subtus crispato-pubescentia. 



Western Hupeh: Ichang, ravines, alt. 500 m., May 1907 (No. 

 3539, in part; bush 1 m. tall, flowers greenish yellow); Hsing-shan 

 Hsien, ravines and roadsides, alt. 300-900 m., May 1907 (No. 3539, in 

 part; bush 0.6 m. tall, flowers greenish). 



This variety differs from the type only in its leaves being pubescent beneath. 

 Pax in his description mentions both forms, but from the fact that he enumerates 

 the glabrous specimens first, it may be assumed that he considers the glabrous form 

 the typical one. 



Andrachne hirsuta Hutchinson, n. sp. 



Frutex gracilis, 0.75-2 m. altus; ramuli patuli, foliosi, leviter flexu- 

 osi, graciles, paulum angulares, parce vel subdense pilosi. Folia lan- 

 ceolata v. ovato-lanceolata, subacute acuminata, basi obtusissima v. 

 rotundata, 2-3.5 cm. longa, 0.7 -1.5 cm. lata, chartacea, supra leviter, 

 infra dense adpresse pubescentia; nervi laterales utrinsecus 4-5, supra
