4. D. speciosa, Kurz in Journ. As. Soc. 1873, pt. ii. Var..a only, 

 leaves large lanceolate thinly hairy on both surfaces, bracts ^-| inrspathu- 

 late-oblong obtuse hirsute glandular-hairy. 



PEGU; Kurz. 



Stem terete, glabrous, except towards the top. Leaves 8 by 2| in., acuminate at 

 both ends ; petiole 1^ in. Cymes 1-li in., axillary, often several together, sometimes 

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

 | in., linear; proper bracts ^ in. broad, on cinereous-pubescent peduncles ^ in. long. 

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

 dulose-pubescent, 4-seeded. 



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

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

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

 Dalz. $ Gibs. Bomb. Fl 196 ; Wight III. t. 164 b, fig. 10, and Ic. t. 1551 ; 

 T. Anders. Thwaites Enum* 235, and in Journ. Linn. Soc. ix. 519, not 

 of Juss. 



W. DECCAN PENINSULA from the Concan southward, and CEYLON ; frequent. 



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

 2 in., base shortly acuminate ; petiole in. Inflorescence variable ; in the type of 

 Wight running into terminal panicles, upper floral leaves linear, peduncles |-1 in. ; 

 more often cymes axillary, abbreviated, peduncles ternate ; or peduncles subobsolete, or 

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

 men, often only \ in. broad, never acuminate, either cuneate or subobtuse mucronate, 

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

 \$ 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 Rheede Sort. Mai. ix. t. 43, which cannot represent the present plant 

 (and may be Peristrophe montana). D. bivalvis, Juss., can, therefore, not even 

 partim be the present D. zeylanica. 



** Inflorescence clustered sulcapitate, i. e. each pair of bracts, sulsessile 

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



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

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

 peduncled, bracts obovate elliptic or cuneate apiculate or mucronate nearly 



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

 usticia umbellata, Wall. Cat. 2467. 



S. MADRAS ; Wight, &c. ; Tinnevelly, Seddome. 



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

 tate cluster; these clusters often on a peduncle i-l| i n -> 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 

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

 mucronate softly pubescent. 



MEBGUI; Griffith. 



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

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

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

 bracts nearly by in., 1-nerved ; secondary nerves oblique, subpromineut. Corolla 

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

 is possibly a Peristrophe fas Griffith marked it in the field), and greatly resembles 

 P. acuminata \ar.fragilis, except that the flower is smaller.
