Mesoptera. | LXXV. RuBIACEX. (J. D. Hooker.) 137 
fleshy albumen; embryo slender, cylindri¢, occupying the whole axis of the al- 
bumen, hence coiled almost in a circle, cotyledons very short obtuse, radicle 
very long superior. 
1. M. Maingayi, Mook. f. in Gen. Plant. ii. 131. 
Maracca, Maingay (Kew Distrib. 939). 
Branches as thick as a goose-quill. Leaves 8-12 by 4-5 in., ovate or elliptic, aeu- 
minate, brown when dry, glabrous and shining above, rusty beneath; nerves 9-10 
pair, impressed above; petiole } in., very stout ; larger stipule 1 in. Cymes small 
and dense in flower, open in fruit, much branched, hirsute, branches slender. Fruit 
when didymous 4 in. diam., black when dry.—The description of the flowers is aided 
by Maingay’s mss., where the ovules are described as inserted near the base of the 
cell, whence I assumed the plant to, belong to Psychotrie, and so classed it in the 
Genera Plantarum; the fruit, then unknown, shows it to belong to Vangueriee, though 
it resembles more outwardly that of an Zora. 
TRIBE XI. IXOREÆ. 
66. IXORA, Linn. 
Shrubs or small trees; branches terete. Leaves opposite, rarely in threes; 
stipules interpetiolar. Flowersin terminal 3-chotomously branched often corym- 
biform cymes, 2-bracteolate, very rarely 5-merous. Calyx-tube ovoid ; limb 4- 
toothed, persistent. Corolla-tube long, very slender ; lobes 4, spreading, twisted 
in bud. Stamens 4, on the mouth of the corolla; filaments short or O, rarely 
half as long as the anther; anther slender, tip often mucronate, base 2-fid. 
Ovary 2-celled ; style filiform, exserted, never twice as long as the corolla-tube ; 
stigma slender, fusiform; branches 2, rarely persistently connate ; ovules soli- 
tary, peltately attached to the septum in each cell. Fruit globose or didymous 
with 2 plano-convex or ventrally concave coriaceous pyrenes. Seeds peltate, 
testa membranous, albumen horny ; cotyledons flat thin, radicle inferior.— Dıs- 
TRIB. Species about 100, tropical Asiatic and African, rarely American. 
A genus with difficulty distinguished from the l-ovuled species of Webera, ex- 
cept by habit, tho slender corolla-tube, and 4-merous flowers. The species are 
most diffieult to limit and diagnose, and the subdivisions here proposed are only 
approximately reliable. Probably more of the Indian species are referable to Malayan, 
and especially Bornean ones than I have ventured to identify with these.  Pavetta 
differs in the bracts and very long style, always twice as long as the corolla. or 
more. 
Sror. I. Huixora. Flowers 4- very rarely 5-merous, 2-bracteolate. 
Corolla-tube very slender. 
* Calyx-teeth longer than the ovary, lanceolate subulate or filiform, Cymes 
corymbiform (except in Z. lanceolaria and Notoniana). 
1. I. acuminata, Roxb. Hort. Beng. 10; Fl. Ind. i. 985 ; glabrous, leaves 
puse elliptic or linear-oblong acuminate coriaceous, floral pair obovate or ob- 
anceolate from a sessile auricled or rounded base, cymes sessile or subsessile 
corymbiform contracted dense-flowered, bracteoles elongate subulate, calyx 
Pg teeth lanceolate much longer than the ovary, corolla-tube very slender-
