Phlogacanthus.] cix. ACAKTHACE^E. (C. B. Clarke.) 511 



anthers 2-celled, oblong, muticous, glabrous. Ovary usually glabrous, 

 10-16-ovulate ; style filiform, subsimple at the tip. Capsule elongate, sub- 

 tetragonous, many-seeded from the base. Seeds lenticular, ovate in outline, 

 glabrous or densely shortly hairy. Species 11, endemic in India. 



This genus differs from Q-ymnostachyum in the broader, curved corolla, the glabrous 

 ovary, and the much stouter capsule. The 2 following genera Cystacanthus and 

 Diotacanthus are with difficulty discerned by the form of the corolla. 



* Thyrses or dense panicles terminal. 



1. P. curviflorus, Nees in Wall. PI. As. Ear. iii. 99, and in DC. 



Prodr. xi. 320 ; leaves large elliptic or obovate nearly glabrous, thyrse 

 dense closely villous, calyx-teeth ^ in., corolla If in. tubular curved scarcely 

 widened upwards. JBot. Mag. t. 3783 ; T. Anders, in Journ. Linn. Soc. ix.

KHASIA MTS., alt. 0-4000 ft. ; frequent on the southern face, Wallich, &c. 



Stem 3-6 ft., stout, glabrous, puberulous upwards. Uppermost leaves often 12 by 

 4-5 in., acuminate at both ends, subentire, punctulate on both surfaces, nerves beneath 

 sometimes puberulous; petiole 2 in. Thyrse 4-8 in., short-peduncled ; bracts | in., 

 linear. Calyx-tube-^ in. ; teeth sublinear, closely villous. Corolla densely villous, 

 brick-red or orange; limb small, lobes hardly patent. Stamens glabrous, 2 small 

 rudiments present. Style thinly hairy. Capsule 1 by in., glabrous, 12-14-seeded. 

 Seeds in. diam., much compressed, glabrous. Wallich says the flowers are bright 

 orange-red ; it is generally a brick- red obscurely orange; it is not known wild of the 

 colour depicted by Wallich, or in Bot. Mag. 



VAB. brevicalyx ; calyx-teeth scarcely | in. Pegu ; Kurz. Moulmein ; Parish. 

 Tenasserim; Beddome. A shrub, 15 ft. (Beddome). Thyrse much less densely villous 

 than in P. curviflorus type. Sepals without sometimes nearly glabrous, much shorter 

 than in P. curvijlorus type. Flowers greenish-yellow (Parish). T. Anderson is 

 mistaken in supposing that this variety is cultivated in Lower Burma, and not wild. 



2. P. Wallichii, Clarke-, leaves large elliptic acuminate at both 

 ends glabrous, thryse dense closely villous, calyx-teeth in., corolla f in. 

 tubular curved scarcely widened upwards. P. asperulus, Wall. Cat. 7171 

 partly, not of Nees. Loxanthus Gomezii, Nees in Wall. Cat. 7170, and 

 in Wall. PI. As. Rar. iii. 99, and in DC. Prodr. xi. 322, partly. 



KHASIA MTS.; Gomez. JAINTEA HILLS ; Jarain, alt. 3000 ft., Clarice. 



Leaves 10 by 3 in., subentire; petiole 1 in. Thyrse 2-4 in., short-peduncled ; 

 bracts | in., linear. Calyx-tube ^ in., teeth linear-lanceolate villous. Corolla 

 densely villous, red ; limb small, lobes subequal, scarcely patent. Stamens and style 

 glabrous. Resembling P. curvijlorus, but with a smaller thyrse, and very much 

 smaller corolla. 



3. P. tubiflorus, Nees in Wall. PL As. Rar. iii. 99, and in DC. 



Prodr. xi. 321 ; leaves large elliptic or ovate narrowed at both ends softly 

 pubescent beneath, panicles elongate dense somewhat pubescent, calyx-teeth 

 in., corolla f in. tubular curved scarcely widened upwards. T. Anders, in 

 Journ. Linn. Soc. ix. 506, partly. Justicia tubiflora, Wall. Cat. 2428.

Leaves attaining 10 by 3-5J in., subentire or crenulate, densely punctulate above, 

 almost woolly (but deciduously) pubescent beneath; petiole 1-2 in., pubescent.
