Ga&rtnera.~\ xcvi. LOGANIACEJJ. (C. B. Clarke.) 91 



DECCAN PENINSULA, extending north-west to the Sone river. PEOME ; Kurz. 

 CEYLON frequent. 



A tree, attaining 40 ft. Leaves 2\ by 1 in., acute at both ends, hardly acuminate. 

 3-nerved from the base or more often the lateral nerves springing much higher, or 

 (as depicted by Koxburgh) sub-penninerved ; petiole ^ in. Peduncles 0-i in. ; cymes 

 1 in. diam., nearly glabrous ; pedicels hardly any. Corolla-tube - in., hardly twice 

 as long as broad, hairy within, nearly glabrous in the throat; lobes ^-^ in. Anther- 

 cells oblong, glabrous. Stylo, long, glabrous ; stigma small, capitate. Seeds ^ in. 

 diam., hemispheric, subpeltate, hardly discoid The clearing-nut. 



7. GAERTNERA, Lamk. 



Trees or shrubs. Leaves opposite, rarely ternate, entire, coriaceous, feather- 

 nerved; stipules connate into a cylindric sheath. Cymes terminal (axillary in 

 G. obesd) many- (or 3-1-) flowered. Calyx small, funnel-shaped or campanu- 

 late. Corolla-tube longer than the calyx or elongate ; lobes 5-4, valvate in bud. 

 Stamens upon the corolla-tube ; filaments short. Ovary 2-celled ; style short 

 or long, stigmas 2 linear or clavate ; ovule 1 in each cell, erect. Berry didy- 

 mous, subglobose, crustaceous. Seeds often compressed, albumen horny or 

 fleshy ; embryo small. SPECIES 25 ; tropical Asia and Africa. 



So closely resembling Psychotria (except for the inferior ovary) that it has been 

 confounded therewith, and it has been proposed to append the genus to Psychotria as 

 an aberrant section. Psychotria, Wall. Cat. 8341, without habitat, is a Gaertnera, 

 but probably non-Indian. 



1. G. KLoenig-ii, Wight Ic. t. 1318; leaves elliptic Qr obovate-oblong 

 shortly acuminate glabrous, panicles terminal trichotomous, calyx wide-funnel- 

 shaped sub- truncate, corolla 5-merous tube about twice as long as the calyx, 

 stigmas thick. Benth. in. Journ. Linn. Soc. i. 112 ; Thwaites Enum. 202 ; Bedd.

SINGAPORE ; Wallich. CEYLON.; alt. 0-3000 ft., very abundant, Thwaites, &c. 

 DISTRIB. Malaya. 



A large shrub. Leaves 6 by 2% in., base narrowed ; petiole 5-3- in. Panicles 2-6 

 in., pubescent or nearly glabrous, sometimes with leafy bracts below; pedicels 0-| in. 

 Calyx YO in. long and broad. Corolla-tube in., throat very villous. Anther-cells ~$- 

 1*0 in., slightly exserted. Berry ^-^ in., obovoid or subglobose. The flowers are, as 

 stated by Beddome, somewhat dimorphic. 



VAR. oxyphylla ; leaves smaller lanceolate acuminate, style short, stigmas small 

 linear. Psychotria oxyphylla, Wall. Cat. 8374 ; Benth. in Journ. Linn. Soc. i. 1^2. 

 Singapore, Wallich. United with G. Koenigii by Thwaites ; the differences in the 

 stigma are probably sexual. 



VAR. divaricata ; panicle lax, pedicels divaricate, flowers rather smaller. G. di- 

 varicata and Pristidia divaricata, Thwaites Enum. 149 and 420. Ceylon; Thwaites. 

 United with G. Koenigii by Beddome, and it does not seem separable from some of 

 the Ceylon G. thyrsiflora which has flowers smaller than usual in lax panicles. 



2. Gr. viminea, Hook. f. ms. ; leaves lanceolate caudate-acuminate 

 glabrous, panicles terminal trichotomous, calyx very small substellate, corolla 

 4-merous tube 2-3 times as long as the calyx, stigmas linear. Psychotria 

 viminea, Wall. Cat. 8354. 



SINGAPORE; Wallich. 



Branchlets terete, smooth. Leaves 3 by f in., base cuneate ; petiole - in.
