514 XXXIII. HUTACE^. (J. D. Hooker.) 



A small tree, head bushy ; branches green, terete,, the old with long sharp thorns, 

 the young with two axillary ones. Leaflet 2-4 in., very thick and coriaceous, tip 

 rounded, margin sometimes crenulate, both surfaces alike and of a very opaque and 

 ashy green when dry, with a few very obscure homontaLjierves not reticulated like the 

 other species, green mottled with white when fresh ; petiole ^-i in., with no traceof 

 articulation, .fiacemes f-l J in., glabrous, 6-8-flowered. Floicers pure white, ^-| in. 

 diam., buds globose. Calyx very small, lobes acute. Petals obovate. Filaments 

 slender, quite free ; anthers obtuse. Ovary 4-5-celled, narrowed at the base, crowning 

 the d;sk ; style cylindric. Berry globose, upwards of 1 in. diam., 4^5-celied ; cells 

 l-seeded, full of glutinous fluid. ISeeds oblong. — A very distinct and curious species, 

 the texture and nervation of the leaf differ wholly from its congeners, and resemble 

 those of Triphasia. Wight (from whom most of the above description is taken) states 

 that the ovarian cells have several ovules, but this is certainly an error.

21. CITXtVS, Linn. 



Shrubs or trees, usually spinous. Leaves alternate, 1-foliolate, coriaceous, 

 persistent ; petiole often winged. Flowers axillary, solitary fascicled or in 

 small cymes, white or pinkish, sweet-scented. Calyx cupular or urceolate, 

 3-5-fid. Petals 4^8, linear-oblong, thick, imbricate. Stamens 20-60, in- 

 serted round a large cupular or annular disk ; filaments variously connate, 

 compressed at the base; anthers oblong. Ovary a) -celled; style stout 

 deciduous, stigma capitate ; ovules 4^8, 2-seriate in each ceU. Berry 

 large, oblong or globose, fleshy, many-celled, septa membranous, cells few- 

 seeded and filled with horizontal fusiform cells distended with juice. 

 ISeeds horizontal or pendulous, testa coriaceous or membranous; embryo 

 sometimes 2 or more in one seed, cotyledon? plano-convex, often un- 

 equal, radicle small, superior. — -Disteeb. About 5 tropical Asiatic species, 

 and 2 Australian, 



C. japonica, I'hnnb. (C. inermis, Boxb. Fl. Ind. iii. 393), the Kumquat, is not cul- 

 tivated in India. I have followed Dr. Brandis's excellent work closely in regard to the 

 forms of this difficult genus. 



1. C> medica, Linn. ; young shoots glabrous purple, leaflet glabrous, 

 flowers often unisexual, petals generally more or less pink, fruit globose 

 ovoid or oblong often mamillate at the apex. 



Valleys along the foot of the Himalaya from Gabwhal to Sikkim, ascending to 

 4000 ft. ; the Khasla Mts. ; Gakkow Mts., Boxburgh ; Chittagonq, H. f. & T. ; 

 and the Western Ghats and Salpura range in Central India. 



A shrub or small tree, flowering and fruiting at most seasons, gi'owing where I found 

 it on steep hill sides (in Sikkim). Leaflet 3-6 in., elliptic-ovate or ovate-lanceolate; 

 petiole naked or winged. Flowers 5-10 in a raceme, small or middle-sized. Stamens 

 20-40. — ^The following are the principal varieties, of which I have found one truly 

 wild in Sikkim, with an oblong leaflet 4 in. long, margined petiole, pink flowers 1 in. 

 long, narrowly ellipsoid, rough fruit 7 in', long, of which the upper 2 in. are contracted 

 into a long conical mamilla, the rind is very thick, and pulp pale yellow. The petals 

 pass into stamens, which would suggest its not being indigenous, but I did not doubt 

 its being so when I gathered it, mainly on dry sunny slopes totally unsuited for any 

 kind of cultivation, wheie it formed large bushes. 



Vab. 1. medica proper ; leaflet oblong, petiole short margined or not, flowers usually 

 numerous, fruit large oblong or obovoid, mamilla obtuse, rind usually warted thick
