Frutex 0.6 m. altus (ex Wilson), ramis gracilibus erectis, ramulis superioribus 

 floriferis plus minusve, interdum fere angulo recto, paten tibus; ramuli hornotini 

 teretes, tenues glabri v. praesertim apicem versus sparse pubescentes, purpuras- 

 centes. Folia membranaceaj opposita, oblonga v. elliptico-oblonga, utrinque 

 acuta, 1.5-3 cm. longa et 0.5-0.9 cm. lata^ supra livido-viridia, subtus pallidiora, 

 utrinque glabra, nervis utrinsccus 5-6 rarius pluribus subtus elevatis; petioli 

 cirvuter 1 mm. longi, glabri, interdum sparse pilosi. Flores lutei sessiles v. fere 

 sessiles, in spicis terminalibus pedunculatis saepe temis ad 1.5 cm. longis sparse 

 pubescentibus ramos et ramulos terminantibus et paniculam gracilcm effusam 

 formantibus; perianthii tubus gracilis 8-9 mm. longus, extus sericeo-pubescens,

 longis: pistillum 4 mm. longum, ovario subclavato apice sparse piloso, stylo dis- 

 tincto 0.2 mm. longo; disci squama unica linearis, apice 2-3 dentata, circiter ova- 

 rium dimidium aequans, interdum ovario fere aequilonga, rarius squama secunda

Yunnan: Szemao, alt. 1500 m., A, Henry (No. 13367, type). Western 

 Szech'uan: Kiating Fu, cliffs, alt. 500 m., June 1903 (Veitch Exped. No. 4436). 



This species seems nearest to W. dolichantha Diels, which differs in its densely 

 pubescent branchlets and in the narrower more or less pubescent leaves. Possibly 

 this is only a glabrous form of W. dolichantha. Wilson's No. 4436 differs slightly 

 from the type in the sparingly pubescent branchlets which are glabrous in the 

 type, and in the more numerous and closer pairs of veins of the leaves. 



23. Wikstroemia scytophyUa Dials in Not. Bot. Gard. Edinburgh, V. 2S6 (1912). 

 Yunnan: betv/ecn Tang-tui and Chiao-tou, alt. 2100-2700 m., September 



1904, G. Forrest (No. 44, ex Diels).

Kwei-chou : "Roule de Pin, Fa k Tui Fan; Tsin Gai," J. CavaleHe (Nos. 1261, 

 1865, exLeveilM). 



This species I know only from the very short description and from a fragment 

 sent by the author and consisting of a few detached leaves and fruits. It is ap- 

 parently a distinct species, but the material is too meagre to make it possible to 

 form an opinion about the affinity of the plant. 



Wikstroemia Bodinieri L^veiUe, Fl. Kouy-Tcheou, 417 (1915). (Syn.: Daphne 

 Bodinien L^veill^ in Fedde, Rep. Spec. Nov. XIII. 258 ([1914]). 



According to a fragment of the type specimen sent by the author this plant be- 

 longs to the Apocynaceae.
