5. Canthidm glabrum, Blume Bijdr. 967. A small unarmed tree : 

 young Jjranclies thinner than a goose-quill, 4-angled, pale-brown when 

 dry, glabrous. Leaves thickly membranous or sub-coriaceous, elliptic or 

 ovate-elliptic, olivaceous and dull when dry, shortly and I'aiher abrupt- 

 ly acuminate, the base slightly and abi"uptly narrowed, or broad and 

 rounded ; upper surface glabrous, the lower with some white sub- 

 adpressed hairs, especially by the sides of the stout midrib and larger 

 nerves ; main-nerves 6 to 8 pairs, spreading, slightly curved, inconspi- 

 cuous on the upper and only slightly conspicuous on the lower surface 5 

 length 5 to 7 in.; breadth 2 to 3 in ; petiole '4 to "6 in. Stipules broadly 

 triangular at the base, much acuminate, shorter than the petioles. 

 Cymes many-flowered, about 1 in. in diam,, on short peduncles, dichoto- 

 mously branched. Flowers pentamerous, •15 in. long, their pedicels 

 slightly shorter. Calyx shortly campanulate or cupulai", the mouth undu- 

 late and with 5 small triangular teeth. Corolla widely tubular, con- 

 stricted at the throat, the limb with 5 deep valvate bi-oadly lanceolate 

 acute spreading or reflexed lobes. Anthers ovate, on short filaments in 

 the throat, with a line of vertically deflexed stout white hairs just below 

 them, fi^i^tna large, sub-globular, rather turbinate, corrugated. Ovary 

 5-celled. Fruit ellipsoid, pulpy, 4-angled (when dry) often compressed, 

 smooth outside, the two enclosed pyrenes triangular, the inner face of 

 each being flat, the outer faces deeply grooved so as to leave a bold 

 central keel. DC. Prod. IV, 478 : Hook. fil. Fl. Br. Ind. Ill, 133. Plec

In all the provinces : common. 



This species is easily distinguished from C. didymum by its short widely tubular 

 corolla slightly constricted just below the limb, that of C. didymum being hypocra- 

 teriform with a narrow tube. The fruit of this is also large and quite glabrous. 



6. Canthium didymum, Gaertn. fil. Fruct. Ill, 94. A tree : young 

 branches without spines, nearly as thick as a goose-quill, 4-angled, at 

 first brown, but afterwards pale, smooth, the nodes thickened. Leaves 

 thinly coriaceous, glabrous, narrowly elliptic or ovate-lanceolate, occa- 

 sionally sub-orbicular, the apices sub-acute, acute or shortly and bluntly 

 acuminate, usually much narrowed at the base, but sometimes rounded ; 

 upper surface dark-brown when dry, shining, the lower paler : main- 

 nerves 3 to 5 pairs, slightly curved, ascending, thin but prominent on 

 the lower surface as is the midrib, faint on the upper; length 2-5 to 

 6 in.; breadth 1-5 to 3-5 in.; petioles -25 to -3 in.; stipules -25 in. long,
