Didiptera.] cix. ACANTHACE^E. (C. B. Clarke.) 551 



larger than the calyx (except in D. parvibracteata) ; flowers sessile, oppo- 

 site, one of each pair usually reduced to a rudimentary calyx and bracteoles ; 

 bracteoles linear or linear-lanceolate, as long as the calyx (except in D. 

 parvibracteata}. Calyx sub-5-partite ; segments equal, linear-lanceolate, 

 more or less pubescent. Corolla red or rose, purple-spotted, tube slender, 

 limb deeply 2-lipped ; upper lip entire or emarginate, lower 3-lobed recurved. 

 Stamens 2 ; anthers 2-celled ; cells ovoid, superposed, muticous. Ovan/ 

 4-ovulate ; style filiform, shortly bifid. Capsule clavate, stalk solid; pla- 

 centae rising elastically from their base. Seeds ovoid, compressed, glabrous, 

 verrucose or glandular subpapillose. Species 60, tropics of both Hemi- 

 spheres. 



Justicia chinensis, Vahl, Eoxb. Fl. 2nd. i. 124, Wall. Cat. 2466 (type sheet), 

 has been long cultivated at Calcutta, having been introduced from China or Malaya ; 

 it looks like an enlarged or garden form of D. Burmanni, noticed below under D. 

 Leonotis, Dalz. 



* Inflorescence panicled, i. e. each pair of bracts mostly long-petioled. 



1. D. parvibracteata, Nees in Wall. PI. As. Ear. iii. Ill, and in 

 DC. Prodr. xi. 488 ; leaves ovate acuminate nearly glabrous, bracts -j'g in. 

 linear. Justicia retorta, Vahl Enum. i. 150 ? J. latebrosa, Koen. Roxb. 

 Fl. Ind. i. 125. 



MADRAS ; Circars, Wight (Herb. Propr. n. 51 or 2014) ; Vizagapatam (Jaipoor 

 Hills), Beddome. 



Stem diffuse, striate, obscurely pubescent upwards. Leaves 5 by 2f in. (or nil 

 except the lowest small, 1-2 in.), base shortly acuminate .; petiole 1 in. Panicle 6 in., 

 divaricate, lax, nearly glabrous ; floral leaves at the bifurcations T 'JJ-| in., linear-lan- 

 ceolate; bracteoles ^ in., linear. Calyx T ' 6 in., sub-5-partite; segments linear-lan- 

 ceolate, minutely pubescent. Corolla | in., slender, minutely pubescent. Capsule 

 \ in., clavate, pubescent ; placentae rising elastically. Justicia latebrosa, Koen., has 

 never been satisfactorily recovered. The Ic. Ined. of this at Kew is D. parvibracteata ; 

 a separate imperfect drawing of a capsule added in the corner perhaps not pertaining. 

 But Roxburgh's description does not suit in several points, of which " Flowers large " 

 is difficult to get over. A scrap in Wallich's Herbarium, marked in old handwriting 

 " Justicia latebrosa, Roxb. ," is Didiptera cuneata. 



2. D. Beddomei, Clarke ; leaves ovate acuminate minutely pubescent, 

 bracts in. linear-oblong suddenly mucronate ciliate. 



N. MADRAS ; Nallaymallays (in Kurnool), Beddome. 



Stems diffuse, striate, glabrous except the tips. Leaves 5J by 3 in., pubescen 

 beneath or nearly glabrous, base acuminate; petiole 2 in. Panicle 6 in., lax 

 branches often patently white-hairy; floral leaves at the bifurcations gradually 

 reduced, uppermost linear ; bracteoles in., linear-lanceolate. Corolla f in., minute!} 

 pubescent. Capsule nearly % in., clavate, pubescent ; placentae rising elastically fron 

 the base. Seeds verrucose. 



3. D. HLurzii, Clarke ; patently white-hairy, leaves lanceolate, bracts 

 ^ in. linear-lanceolate hirsute glandular-hairy. D. speciosa, Var. ft only, 

 Kurz in Journ. As. Soc. 1873, pt. ii. 97. 



PEGU; Kurz. 



Stem stout, striate, patently white-hairy. Leaves 5 by 1 in., acuminate at both 

 ends, thinly hairy on both surfaces; petiole \ in. Panicle 6-15 in., divaricate, lax, 

 patently white-hairy ; bracts and bracteoles with glandular hammer-headed hairs, 

 and also white-hirsute. Corolla -f in., slender, minutely hairy. Capsule l i n ., 

 clavate, pubescent, placenta) rising elastically. Seeds verrucose. Placed doubtfully 

 as a var. of D. speciosa by Kurz j the inflorescence is different, and the corolla is 

 considerably smaller.
