Bl. 8f HC. U. CO. Zwardekronia lurida, Korth. in Ned. Ki-uidh. Arch. ii. 252, 

 Ixoi-a attenuata, Wall. Cat. 6164. Psyctotria, Wall. Cat. 8361, 8362, 8363, 

 8364 {in part), 8375, 8386 (a very narrow-leaved form), 8390. Rubiacea, 

 Wcdl. Cat. 8461. 



Eastern Tropicai. Himalata ; Sikkim, alt. 2-6000 ft. Assam, Cacbar, and the 

 Khasia Mts., ascending to 5000 ft. Tenasserim, the Andaman Islands, Malayan 

 Peninsula, and Penanq. Western Peninsula; the Ghats from Bombay south- 

 wards. Ceylon, ascending to 4000 ft. — Distrib. Malay Islands to Borneo. 



An evergreen small weak shrub 2-4 ft. high. Leaves greenish when dry, in the 

 most frequent form ohovate-lanceolate 4-6 by li-2J in. diam., narrowed into a, 

 slender petiole ^3 in. long ; in a common Malayan form almost elliptic, in Tenas- 

 serim ones 8-10 by 1^-2^ in. ; in Ceylon ones they vary from 2J-5 by ^-1^ in., 

 always membranous with slender distant nerves, arching upwards ; stipules triangular 

 or ovate or broader, acute obtuse or rounded, entire or 2-fid, often connate and per- 

 sistent. Cymes rarely 2 in. long, more or less pyramidal or rounded ; peduncle 2 in. 

 long and under ; branches short, soft, rather stout, often purplish ; bracts persistent, 

 ovate-lanceolate or subulate; flowers J-§ in. long, sufascioled, sessile, 4^6-merous. 

 Cah/x short, teeth triangular. Corolla variable in length, dimorphic, one form with 

 exserted anthers and included stigmas, the other with these positions reversed ; throat 

 glabrous. Fruit size of a pea, globose, more or less didymous, smooth ; pyrenes thin. 

 Seed orbicular and cupular, smooth. — This plant was first published as a Chasalia by 

 Miquel, in 1856, under the name of C. hmda, founded on Blume's Psychotria lurida ; 

 but Wallich's P. cwrviflora antedates Blume's lurida by two years, and as it is by far 

 the most expressive specific name, and is also taken up as a Chasalia by Miquel after 

 Thwaites {Arm. Mus. iMgd. Bat. iv. 202), I adopt it here. 



Vab. 1. longifoUa; leaves 8-12 by 1^-2 in., nerves more numerous spreading. 

 Psychotria longifolia, Balz. in HooJc. Land. Jown. Bot. ii. 133, not of Beddome. 

 Psychotria, Wall. Cat. 8386. — Cachar, Keenan; Bombay, Salzell, Stocks; Malacca, 

 Maingiay (Kew Distrib. 3052). — Though so dissimilar, this is obviously an extreme 

 form of C. cwviflora, connected by intermediates ; indeed, one specimen (from Cachar) 

 has the lower part of the leaf with the numerous spreading nerves of the variety, and 

 the upper part with the distant arched ones of the type. 



Var. 2. elUpsoidea ; leaves as in the common form of the species, fruit ellipsoid. 

 — Khasia Mts. ; Jarain in Jyntea, alt. 3000 ft., C. B. Clarke. 



2. C> rostrata, Miq. in Ann. Mus. iMgd. Bat. iv. 203, e.v6l. syn. tetrandra; 

 glabrous, leaves short-petioled elliptic-lanceolate caudate-acuminate, cymes ter- 

 minal pedimcled very small lax-flowered bracteate, corolla-tube very short. 

 Psychotria rostrata, Bl. and Polyozus latifolia {fid. Miquel), Bl. Bijd. 961, 

 948; DC. Prodr. iv. 531, 494. 



Malacca, Griffih (Kew Distrib. 3045), Maimgay (n. 937). — Distrib. Java. 



Branches slender. Leaves 4-5 by f-lj in., greenish when dry, membranous, base 

 acute ; nerves 6-8 pair, arched ; stipules short, broad, entire or toothed. Cymes 

 slender, trichotomous, branches often drooping, few-flowered ; bracts subulate ; flowers 

 minute. Calyx-teeth triangular. Corolla glabrous. Fruit much as in C. cwrviflora. 

 — This unites Psychotria and Chasalia, having the flowers of P. montana and fruit of 

 C. curviflora.
