Subgen. 2. AXILLANTHUS K. Schumann in Engler & Prantl, Nat. Pflanzen- 
fam. 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 believe, 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 haveseen. Theripe fruit on the specimens before me of T. azillare (Henry's 
Nos. 9854, 9854) may be described as follows: folliculi 13 em. longi, medio ad 
1.8 cm. lati, fere paralleli, apicem versus angustati, paulo incurvi, ima apice co- 
haerentes (vide juniores in No. 9854>,) glabri, cinereo-fusci; 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. PSEUDAXILLANTHUS 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 Azillanthus. The 
sepals are comparatively long, and the ovary is hairy as in Lachnocarpus. The 
fruits are not yet known.

By the kindness of Mgr. Léveillé this Arboretum has received a fragment of 
one of his type specimens. According to this specimen this species represents & 
very distinct new subgenus well distinguished by the characters given in the key 
on p. 337 and above.
