Erantkenumi.] cix. ACANTHACE^E. (C. B. Clarke.) 497 



XXVI. ERANTHE1VIUIVI, Linn. 



Stamens 2 fertile, 2 rudimentary or 0. Ovary often glabrous. Otherwise 

 as Asystasia. Species 30, tropics of both hemispheres. 



E. diantherum,5oa?J. Fl. Ind. i. 112, Wall. PI. As. Ear.\\\. 108, and E. racemosum, 

 Roxb. 1. c. 113, Wall. I. c. 107, DC. Prodr. xi. 455, came froin the Moluccas. 

 E. semperflorens, Roth Nov. Sp. 2, Nees in DC. Prodr. xi. 458, came from Mar- 

 tinique, nor is there reason from Roth's account to believe it otherwise than cultivated 

 by Heyne. Justicia sp., Griff. Ic. PL As. t. 426 (Kew jDistrib. n. 6177), is a fine 

 Eranthemum, collected in Ava, outside the bounds of British India. 



* Corolla tubular-ventricose. 



1. 32. indicum, Clarke; leaves lanceolate or subovate acuminate at 

 both ends glabrous, racemes dense puberulous or glabrate, corolla 1| in. 

 white abundantly purple- veined. Thyrsacanthus indicus, Nees in DC. 

 Prodr. ix. 325. Asystasia thyrsacanthus, T. Anders, in Journ. Linn. Soc. 

 ix. 525. 



SIKKIM and BHOTAN, alt. 1-5000 ft., frequent ; H.f. Sf T., &c. ASSAM, in the 

 lower hills ; KHASIA and JAINTEA MTS., alt. 1-4000 ft., frequent. 



A diffuse undershrub, 1-4 ft. Leaves 7 by 2 in. ; nerves 5-7 pair ; petiole -f in. 

 Racemes 15 in. ; lower pedicels 0-g in.; bracts | ^ in., linear. Sepals gin., linear- 

 lanceolate, glabrous or puberulous. Corolla distinctly 2-lipped, upper lip subentire 

 emarginate galeate, lower 3-fid, middle lobe the widest. Filaments and style minutely 

 hairy. Capsule 1^ in., base long, cylindric, solid. Seeds in., orbicular, tubercled, 

 rugose, glabrous. It is difficult to give a reason why this is not a Thyrsacanthus, ex- 

 cept that it is not American ; the curved subgaleate corolla does not agree well either 

 with Asystasia or Eranthemum. 



** Corolla-tube linear -cylindric, often very narrow. 



2. E. crenulatum, Lindl. in Bot. Reg. t. 879, not of Nees ; leaves 

 lanceolate or elliptic acuminate at both ends, racemes slender glabrous or 

 puberulous, flowers solitary, corolla pale purple or lilac tube in. slender 

 narrowly funnel-shaped upwards, ovary glabrous. 



KHASIA TEEAI, alt. 0-2000 ft., frequent ; Wallich, H.f. Sf T., &c. 



Perennial ; 18 in., glabrous. Leaoes 6| by 2 in., undulate-creuate ; nerves 8 

 pair ; petiole ^ in. Racemes in a terminal panicle with curved drooping slender 

 branches; bracts in., linear-lanceolate; pedicels 0-| in. Sepals in., sublinear, 

 glabrous or puberulous. Corolla-limb obscurely 2-lipped, | in. diam. Stamens 2, 

 subincluded. Capsule f in. ; cylindric base ] in. Seeds in., rugose, glabrous. 

 Lindley's picture is excellent, but shows a small example in young flower ; the panicle 

 is often 8-12 in. diam., the flowers becoming distant on the branches. The species 

 has been quite lost sight of by Nees and T. Anderson, Hooker's examples having 

 (probably from the short corolla) been referred to Codonacanthus. 



3. E. malabaricum, Clarke ; leaves elliptic or ovate narrowed at 

 both ends glabrous, spikes glabrous or puberulous, corolla white or yellowish 

 tube 1-1 in., ovary glabrous. E. crenulatum, Wall. Cat. 2491 ; Dalz. 8f 

 Gibs. Bomb. Fl. 195 ; T. Anders, in Thwaites Enum. 235, and in Journ. 

 Linn. Soc. ix. 523, chiefly. Justicia latif olia, Vahl Symb. ii. 4 ? 



W. DKCCAN PENINSULA, frequent; Wight, Hohenacker. CEYLON; Thwaites 

 (C. P. n. 1979). 



Suffrutescent, 2 ft. high. Leaves 5 by 2| in., uudulate-crenulate, minutely 

 lineolate on both surfaces ; nerves 6-7 pair ; petiole l s in. Spikes 4-9 in. ; lowest 

 pedicels obsolete in fruit ; bracts | in., linear-lanceolate. Sepals in., sublinear,
