146 rubiace i \Adhia. 



1. ADINA, Salisb. 



Calyx-limb of 5 persistent linear lobes. Corolla-tube slender; lobes 5, 

 valvate in the bud. Anthers included in the tube. Style exserted, with a 

 capitate stigma. Ovary 2-celled, with few ovules suspended from near the 

 top of the cells. Fruit capsular, septicidal, the 2 valves and seeds falling off, 

 leaving a persistent axis crowned by the star-like limb of the calyx. Seeds 

 oblong, with a narrow edge or wing. — Shrubs. Stipules united in pairs be- 

 tween the leaves. Flowers densely crowded in globular heads, on axillary or 

 terminal peduncles. 



Besides the following species, the genus comprises one other, the A. polycephala, Benth. 

 {Nauclea polycephala, Wall. Catal.n. 6100), with several flower-heads, forming a short ter- 

 minal raceme or corymb, which extends from Silhet and Chittagong to the vicinity of Hong- 

 kong, but has not been found in the island itself. We have also from S. China, but not yet 

 from the island of Hongkong, a species of the closely allied genus Cephalanthus, which can 

 neither be distinguished from some forms of the American C. occidentalis, nor from others of 

 the Asiatic C. naucleoides ; the glabrous and pubescent varieties occur both in America and 

 Asia, and the glands of the corolla are sometimes as large in the American as in the Asiatic 

 specimens. 



1. A. globiflora, Salisb. ; DC. Prod. iv. 349. An erect glabrous much- 

 branched shrub. Leaves shortly stalked, oblong or obovate-lanceolate, acu- 

 minate, 1 ^ to 3 in. long. Peduncles axillary or rarely 3 together at the ends 

 of the branches, shorter or longer than the leaves, each with 2 small bracts a 

 little below the middle, and bearing a single globular flower-head, about 5 

 lines diameter, without the long exserted styles. — Nauclea Adina, Sm., and N. 

 adinoides, Lindl. Bot. Keg. xi. t. 895. Adina pedunculata, DC. Prod. iv. 349. 



Common in ravines, Champion and others ; also on the adjacent continent, but not known 

 out of S. China. 



2. THYSANOSPERMUM, Champ. 



Calyx-limb of 5, or rarely 4 persistent short lobes. Corolla-tube slender ; 

 lobes 5, rarely 4, spreading, imbricate in the bud. Anthers linear, included 

 in the tube. Style entire, club-shaped at the top, exserted. Ovary 2-celled, 

 with several peltate ovules in each, imbricated upwards, the placenta peltately 

 attached to the middle of the partition. Capsule nearly globular, opening 

 loculicidally in 2 valves which split septicidally. Seeds bordered by a fringed 

 membranous wing. — Flowers axillary, solitary. 



The genus comprises only a single species. 



1. T. diffusum, Champ, in Kew Journ. Bot. iv. 168. A low prostrate 

 or trailing shrub, the slender branches covered when young with appressed 

 hairs. Leaves shortly stalked, ovate or ovate-lanceolate, acutely acuminate, 

 1 to \\ in. long, glabrous above, with appressed hairs on the midrib and 

 edges underneath. Stipules single on each side,' lanceolate, entire. Pedun- 

 cles axillary, solitary, 1 -flowered, 2 to 3 lines long, with 2 minute bracts above 

 the middle. Calyx scarcely 1 line long, the ovate lobes scarcely as long as 

 the globose tube. Corolla white, the tube 5 lines long, pubescent ; the lobes 

 near 2 lines long, obtuse, pubescent inside. Capsule like that of a Hedyotis, 

 with about 10 seeds to each cell. - 



In ravines, trailing upon rocks, abundant on Mount Victoria and some other places, Cham- 

 pion ; also Wright. Not received from elsewhere.
