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

 centes. Folia membranacea, 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 utrinsecus 5-6 rarius pluribus subtus elevatis; petioli 

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

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

 pubescentibus ramos et ramulos terminantibus et paniculam gracilem effusam

 euperiores faucem vix attingentes, inferiores supra medium affixae, filamentisO.2 mm. 

 longis: pistillum 4 mm. longum, ovario subclavato apice sparse piloso, stjdo 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: Kaating 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 scytophylla Diels in Not. Bot. Gard. Edinburgh, V. 286 (1912). 

 Yunnan: between Tang-tui and Chiao-tou, alt. 2100-2700 m., September 



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



Species imperfecte notae v. excludendae. 



Wikstroemia Valhrayi Leveille, Fl. Kouy-Tcheou, 417 (1915). 



Kwei-chou : "Roule de Pin, Fa a TuiFan; TsinGai," J.Cavalerie (Nos. 1261, 

 1865, ex Leveille). 



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 Leveille, Fl. Kouy-Tcheou, 417 (1915). (Syn.: Daphne 

 Bodinieri Leveille 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.
