Cascaria.~\ LXIII. SAMYDACE^;. (C. B. Clarke.) 591 



3-fid at the apex, or styles 2-5 ; ovules many or several, placentas 2-5 (usually 

 3)', parietal. Fruit loculicidally 2-5- (usually 3-) valved, valves carrying the 

 seeds on their medial line. Seeds several (usually few sometimes many), oblong 

 or angular, albuminous, usually drilled. DISTKIB. Species 150, scattered 

 through the tropical regions of th'e globe, rarely also in the subtropical. 



Petals 0, flowers in axillary fascicles 1. CASEARIA. 



Petals 0, racemes slender in a terminal panicle 2. OSMELIA. 



Petals present, racemes axillary and terminal 3. HOMALIUM. 



Shrubs or small trees. Leaves alternate, distichous, petioled, undivided, en- 

 tire or slightly serrate, often minutely punctate beneath ; stipules small, lateral, 

 caducous. Flowers small, greenish-yellow, clustered in the axils (in the Indian 

 species) ; pedicels short, jointed above their base, surrounded by small scales. 

 Calyx inferior, deeply 4-5-lobed ; lobes imbricate, obtuse, persistent. Petals 0. 

 Stamens double the number of calyx-lobes or thereabout, united in a tube 

 with stamii odes alternating with the free portion of the filaments; staminal 

 tube hypogynous, sometimes very short so that the filaments are nearly or quite 

 free. Ovary free, ovoid, 1-celled ; style simple ; stigma capitate or 3-fid ; ovules 

 many, parietal. Capsule succulent, globose or ovoid, ellipsoid (when dry some- 

 what 3-angular or 6-ribbed), 3- rarely 2-valved. Seeds many, angular or obo- 

 void, with a fleshy usually coloured axil ; embryo straight. DISTRIB. Species 

 80, in the warmer parts of the whole globe, most plentiful in America. 



* Adult leaves and petioles glabrous. 



1. C. glpxnerata, Roxb. Hort. Beng. 33; FL Ind. ii. 419; leaves lan- 

 ceolate or elliptic-lanceolate acuminate denticulate or crenate often obscurely 

 and minutely so but never quite entire, acute or obtuse but not rounded cordate 

 at the base, pedicels with minute yellow hair, fruit ^ in., ellipsoid. DC. Prodr. 

 ii. 49 ; Benth. FL Hongk. 122 ; not of Kurz Flor. FL i. 530. 0. ovata, Wall. 

 Cat. 7192 E, not of Roxb. 



SIKKIM, BHOTAX and KHASIA, alt. 3000-5000 ft., common. DISTRIB. Hong Kong 

 (and probably Malaya, for the examples of C. glabrata Miq. collected in Sumatra ap- 

 pear C. glomerata). 



A shrub, or in interior Sikkim a tree 20-30 ft.; branchlets somewhat angular, 

 glabrous, not or but little lenticellate. Leaves commonly 4 by if in. (in Sikkim fre- 

 quently 9 in.) ; petiole 3- in. Pedicels usually very many, | in. Calyx small, more or 

 less pubescent in the bud. Stamens 7-10, staminodes yellow. A plant collected in 

 Sikkim by Mr. Kurz. marked " C. glabra" has bark densely uniformly lenticellate, 

 petioles in. and the young buds and pedicels without the smaller yellow hairs ; 

 it can scarcely be Koxburgh's C. glabra from the Moluccas and which is not repre- 

 sented in the Kew Herbarium. 



2. C. leucolepis, Turcz. in Bull. Soc. Nat. Mosc. 1858, pt. i. 463 ; 



leaves oblong acute crenulate base rounded unequal, pedicels with minute grey 

 hairs. ? C. viridiflora Lamk. Diet. vi. 493. 



SINGAPORE ; T. Lobb. DISTRIB. Java, Philippines. 



Branchlets nearly glabrous. Leaves 5-6 by 2 in. ; petiole ^ in. Pedicels in. ; 



buds minutely hairy, larger than those of C. glomerata. There is a doubt whether 



Thos. Lobb's No. 468 on which Turczaninow founded the species was not collected at 



Luzon instead of Singapore. If so the species has not yet been found in British India.
