4. D. speclosa, Kurz in Jown. As. Soc. 1873, pt. ii. Var. u only ; 

 leaves large lanceolate thinly iairy on both surfaces, bracts ^J in. spathu- 

 late-oblong obtuse hirsute glandular-hairy. 



Pe&tt; Kurz. 



Stem terete, glabrous, except towards the top. Zeaves 8 by 2i in., acuminate at 

 both ends; petiole IJ in. Cymes 1-1 J in., axillary, often several together, sometimes 

 from the lower axils ; mostly subsimply umbelled, rarely compound ; floral leaves 

 § in., linear; proper bracts J in. broad, on cinereous-pubescent peduncles J in. long. 

 Corolla nearly 1 in., lower Up broad. Capsule (immature) clavate, minutely glan- 

 dulose-pubescent, 4-seeded. 



6. D. zeylanica, Nees in DC. Prodr, xi. 474 ; leaves ovate acuminate 

 minutely scabrid or glabrate, bracts ovate or elliptic muoronate glabrous or 

 minutely pubescent. D. bivalvis, Nees I. c. 475 {as to the Indian material); 

 BaU. Sc Gibs. Bomh. Fl. 196; Wight III. t. 164 b, fig. 10, and Jc. 1. 1551 ; 

 T. Anders. Thwaites Enum. 235, and in Journ. Linn. Soc. ix. 619, not 

 of Juss. 



W. Dbocajt PeninsitIiA from the Concan southward, and Cetion ; frequent. 



Stem glabrous, sometimes pubescent or densely woolly. Leaves attaining 5 by 

 2i in., base shortly acumiuate ; petiole | in. Inflorescence variable ; in the type of 

 Wight running into terminal panicles, upper floral leaves linear, peduncles J-l in. ; 

 more often cymes axillary, abbreviated, peduncles temate ; or peduncles snbobsolete, or 

 the inflorescence reduced to one pair of bracts ; bracts J in. broad in the type speci- 

 men, often only { in. broad, never acuminate, either cuneate or subobtuse mncronate, 

 frequently nervose; bracteoles small, linear-lanceolate. Corolla \ in. Capsule 

 J-J in., clavate, pubescent. Seeds minutely verrucose. — Dicliptera bivalvis, Juss., is 

 exactly Justicia- bivalvis, linn.^ which, in so far as it relates to any Indian plant, is 

 founded on Mheede Sort. Mai. ix. t. 43, which cannot represent the present plant 

 (and may he Peristrophe montana). H. bivalvis, Juss., can, therefore, not even 

 partim be the present -D. ze^lanica. 



** Inflorescence clustered suhcapitate, i. e. ea^h pair of hracts, subsessile 

 or very shortly petioled (see also 5, D. zeylanica). 



6. D. cuneata, Nees in Wall. PI. As. Rar. iii. Ill, and in DC. 

 Prodr. xi. 481 ; leaves ovate acuminate glabrous, flower-olusters often long- 

 peduncled, bracts obovate elliptic or cuneate apiculate or mncronate nearly 

 glabrous. Wight Ic. t. 1552 ; T. Anders, in Journ. Linn. Soc. ix. 521. 

 Justicia umbellata. Wall. Cat. 2467. 



5. Madras ; Wight, &o. ; Tinnevelly, JBeddome. 



Pairs of bracts on short peduncles 0-J in., often 3-8 together forming a snhcapi- 

 tate cluster ; these clusters often on a peduncle ^1 J in., floral leaves supporting the 

 cluster usually reduced, narrow. — Otherwise very near the glabrous forms of D. 

 zeylanica with congested inflorescence : both T. Anderson and Beddome have, how- 

 ever, treated the species as distinct. 



7. D. reptans, Nees in DC. Prodr. xi. 483 ; leaves elliptic acuminate 

 pnberulous beneath, flower-clusters axillary subsessile, bracts elliptic acute 

 mncronate softly pubescent. 



Meegtji; Qriffith. 



Stems procumbent, rooting; branches 6-10 in., erect, puberulous. Leaves 3 by 

 1 in., base shortly acuminate ; petiole j in. Peduncles to the flower-clusters 0-^ in.; 

 floral leaves ^ in., hnear; peduncles to the pairs of bracts 0-J in., minutely pubescent; 

 bracts nearly i hy J in., 1-nerved ; secondary nerves oblique, subprominent. Corolla 

 i in., slender. — Capsule not seen ; and anther-cells rather long for a Dicliptera ; it 

 is possibly a Peristrophe (as GriflSth marked it in the field), and greatly resembles 

 P. acuminata yai.fragilis, except that the flower is smaller.
