CHINA. Yunnan : Szemao, forests, alt. 1300 m., A. Henry (No. 11949, type; 

 large climber, white flowers); same locality, forests to southeast, A. Henry (No. 

 12800; fruiting co-type). 



A well-marked species, related to the last as indicated above. 



Subgen. 2. AXILLANTHUS K. Schumann in Engler & Prantl, Nat. Pflanzen- 

 fa?n. IV. Abt. 2, 173 (pro sectione) (1895). 



Trachelospermum, sect, (vel genus nov.) Pycnanthes Bentham & Hooker, Gen. 

 II. 720 (1876), in textu, ut videtur tantum pro parte. 



Bentham & Hooker say that there are two species — one from Sikkim, the other 

 from Khasia — with dense axillary subsessile inflorescences, and they propose the 

 name Pycnanthes for a section of Trachelospermum or for a new genus. The Sikkim 

 species, first mentioned, I beheve, is identical with T. axillare Hooker f ., and there- 

 fore one might accept the name Pycnanthes. With regard to the fruits they say: 

 " folliculi similes nisi rigidiores et magis divaricati." This does not agree with 

 what I have seen. The ripe fruit on the specimens before me of T. axillare (Henry's 

 Nos. 9854, 9854*^) may be described as follows: folhcuU 13 cm. longi, medio ad 

 1.8 cm. lati, fere paralleh, apicem versus angustati, paulo incurvi, ima apice co- 

 haerentes (vide juniores in No. 9854^,) glabri, cinereo-f usci ; valvae satis tenues, sed 

 firmae, intus laeves, flavo-brunneae. Semina lapidea, satis magna, oblonga v. 

 obovato-oblonga, circiter 21 mm. longa, versus basim obtusum circiter 7 mm. lata, 

 apice setifera circiter 2-3 mm. lata, circiter 0.5-1 mm. crassa, sed plus minusve 

 irregulariter curvata et carinata, obscure purpurascentia, infra comam parte paulo 

 flavescente instructa; comae densae, basi flavescentes, ad 5 cm. longae.

Subgen. 3. PSEUD AXILLANTHUS Schneider, n. subgen. Descriptio in clavi. 



The species referred to this new subgenus has the appearance of an Eutrachelo- 

 spermum, while the structure of the flowers is the same as in Axillanthus. The 

 sepals are comparatively long, and the ovary is hairy as in Lachnocarpus. The 

 fruits are not yet known.

By the kindness of Mgr. L^veille this Arboretum has received a fragment of 

 one of his type specimens. According to this specimen this species represents a 

 very distinct new subgenus well distinguished by the characters given in the key 

 on p. 337 and above.
