each. Stigma oblong. Fruit of 2 long linear follicles. Seeds ending in a 

 naiTow neck, with a coma of long silky hairs. — Woody climbers. Leaves op- 

 posite. Flowers in loose terminal tricliotomous cymes, sometimes appearing

 Japan. 



8. AGANOSMA, Don. 



Calyx usually with a ring of glands inside at the base, occasionally with 

 fcAv or none. Corolla-tube cylindrical ; the limb spreading, with oblique nar- 

 row lobes about the length of the tube. Anthers sessile near the base of 

 the tube, not sagittate. Disk annidar or cup-shaped, shortly 5-lobed or 

 nearly entire. Ovary of 2 distinct carpels united by the single style, with 

 several ovules in each. Stigma spindle-shaped or cylindrical. Fruit of 

 2 long linear follicles. Seeds with a coma of long silky hairs. — Woody 

 climbers or shrubs. Leaves opposite. Flowers white, in terminal triclioto-

A small tropical Asiatic genus. 



1. A. Isevis, Champ, in Kew Journ. Bot. iv. 335. An evergreen, gla- 

 brous straggling shrub or climber. Leaves narrow-oblong or lanceolate, acu- 

 minate, 2 to 4 in. long, smooth and shining, with few distant oblique lateral

 tricliotomous cymes or dense panicles at the ends of the branches. Sepals 

 small, narrow-ovate, without glands. Corolla-tube 2 lines long, pul)escent

In a ravine, Chawpion ; at Little Hongkong and West Point, Wilford ; also Hinds and 

 Wright; and on the adjacent continent. This plant differs from the others of the genus in 

 the absence of the calycine glands. I have not been able positively to verify Hooker and 

 Arnott's synonym, for the original specimen of Ilolarrhena affinis cannot now be found in 

 the Hookerian Herbarium.
