168 LXXV. RUBIACE.E. (J. D. Hooker.) \_Psy chotria. 



in., rather thin, red-brown when dry and shining above, midrib and nerves slender ; 

 base narrowed into the slender petiole ; stipules oblong-ovate, deciduous. Cymes 3-4 

 in broad; branches angled, sometimes obscurely puberulous, divaricate, much 3- 

 chotomously divided; flowers pedicelled, minute. Calyx truncate, teeth obscure. 

 Corolla-tube very short, glabrous, villous within. Fruit -| in. long, areolate, calyx- 

 teeth very obscure. Seeds of the section, ventral face plane. A near ally of the 

 Chinese P. elliptica, Ker in Bot. Eeg. t. 607 (P. Reevesii, Wall. Cat. 8330, and in 

 Eoxb. Ft. Ind. ii. 164), but more slender, leaves less coriaceous, with slender midrib 

 and nerves, and smaller flowers. 



25. P. diverg-ens, Kurz For. Fl. ii. 13 ; and in Journ. As. Soc. 1877, ii. 

 143, not of Blume ; glabrous, leaves lanceolate to linear-lanceolate acuminate 

 tapering into a long petiole, cymes long-peduncled trichotomous, flowers shortly 

 pedicelled, calyx-teeth obsolete, fruit ovoid 5-ribbed and furrowed crowned by 

 the calyx-limb. 



PEGU, MALABAR, and TENASSERIM, in tropical forests, Kurz. 



An evergreen shrub, 1^-2 ft. Leaves 5-8 in., firmly membranous or thinly coria- 

 ceous, usually brownish when dry; petiole ^-1 in. ; stipules variable, often very large 

 and elongate, entire or 2-cleft. Flowers greenish. Corolla -^-^ in., lobes as long, 

 throat villous. Fruit ^-\ in. long, smooth. Albumen equable, spuriously ruminate, 

 or rather 5-ribbed. I have seen no authentic specimen, and take the description from 

 Kurz, -who says that it differs from P. andamanica only in the glabrous cymes. It 

 cannot be Blume's P. divergem, which has a prominently toothed calyx and very large 

 flowers ; it is probably a glabrous form of P. sulcata. 



26. P. andamanica, Kurz in Lond. Journ. Sot. 1875, 328 ; For. Fl. ii. 

 13 ; glabrous except the cymes, leaves long-petioled elliptic-obovate or -lanceolate 

 caudate-acuminate, nerves 8-10 pair remote, cymes subsessile much trichoto- 

 mously branched, fruit ellipsoid 8-grooved. 



ANDAMAN and NICOBAR ISLANDS, Kurz. 



A small evergreen shrub ; branches stout, pale, the wood shrinking in drying. 

 Leaves 6-9 by 2|-3^ in., membranous, greenish-brown when dry, often subfalcate ; 

 nerves slender, arched ; base narrowed into the 1-2 in. long petiole ; stipules large, 

 oblong, 2-cleft, deciduous. Cymes glabrous or rusty-puberulous, 3 in. diam., branches 

 divaricate; flowers shortly pedicelled, greenish-white. Calyx almost truncate; teeth 

 short, broad. Corolla glabrous, tube ~ in., much exserted, throat villous. Fruit % 

 in. long, smooth, calyx-limb persistent. I have seen no fruit, nor any Andaman 

 specimens ; it is probably a broad-leaved form of the following. 



27. P. sulcata, Wall. Cat. 8370 ; leaves long-petioled elliptic-lanceolate 

 or oblanceolate acuminate membranous puberulous or glabrate beneath, nerves 

 10-15 pair, stipules very large lax, cymes axillary or terminal sessile or peduncled 

 repeatedly trichotomously divided, fruit pedicelled broadly ellipsoid 8-grooved, 

 calyx very small. 



TENASSERIM, MALABAR, and BIRMA, Wallich, Heifer, &c. 



Branches rather slender, smooth. Leaves 3-9 by 2-2 in., greenish or brown when 

 dry, nerves slender, base narrowed into a petiole -l in. long; stipules ^-| in., 

 straight or falcate, obtuse acute or acuminate, rather persistent for the genus. Cymes 

 small, 1-2| in. diam. ; branches divaricate; bracts triangular; flowers very small, 

 glabrous. Calyx-limb truncate. Corolla-tube glabrous, very short. Fruit % in. long, 

 grooves not deep. Seed flat on the ventral face. 



28. P. erratica, Hook. f. \ glabrous, leaves lanceolate or elliptic acumi- 

 nate, petiole slender, nerves 9-12 pair, stipules usually cleft, cymes axillary and 

 terminal sessile glabrous or puberulous rather shortly trichotomously branched, 

 fruit pedicelled 8-grooved. calyx-limb small.
