1. T. involucrata. Linn. Sp. PI. 980; more or less pubescent hispid 

 or tomentose and with scattered stinging bristles, rarely almost glabrous, 

 leaves from linear-oblong to broadly ovate-cordate acuminate serrate, and from 

 entire to deeply 3-fid or tripartite with irregularly serrate or subpinnatifid 

 lobes, racemes hispid or glabrous, fruiting sepals rigid stellately spreading 

 oblong pinnatifid rarely subentire, ovary hispid, seeds mottled with abroad 

 tumid chalaza. Muell. Arg. in DC. Prodr. xv. ii. 943. Kurz For. Fl. ii.

Throughout INDIA, from the Panjab and lower Himalaya of Kumaon, eastward to 

 Assam and southward to BURMA, TRAVANCORE and CEYLON. DISTRIB. China. 



An evergreen twiner. Leaves 1-4 in., membranous, protean in form and indu- 

 mentum ; petiole long or short. Racemes 1-2 in., slender; bracts small or minute. 

 Male fl. minute, shortly pedicelled ; sepals and stamens 3 ; pistillode 3-fid. Fern. fl. 

 strigosely hispid, fruiting f in. diam. Style-column very variable in length. Capsule 

 ^ in. diam., hispid or strigosely tomentose or nearly glabrous. Seeds obscurely hoary. 

 It is impossible to define the varieties of this most variable plant. The following 

 are the principal forms. 



T. INVOLUCRATA PROPER ; coarsely strigosely hispid, leaves ovate or lanceolate 

 acuminate coarsely toothed or serrate. Var. a. Kheediana, 5. genuina, and 7. hispid;i, 

 Muell. 1. c. T. hispida, Willd. Sp. PL iv. 323. Burm. Fl. Zeyl. 202, t. 92 ; Eheede 

 Hort. Hal. ii. t. 39 ; Wall. Cat. 7791 B, C, D. 



Var. cordata, Muell. I.e. ; leaves (often broadly) ovate-cordate coarsely serrate 

 cuspidately acuminate. T. cordata, Seyne in Wall. Cat. 7791 A. Var. rnontana, 

 Tiiwaites Enum. 270. T. montana, Muell. Arg. I. c. 904. 



Var. angustifolia ; leaves narrowly linear- or oblong-lanceolate base contracted 

 cordate. 



Var. cannabina; leaves all palmately 3-partite with narrow toothed or pinnatifid 

 lobes. Var. e. intermedia and canuabina, Muell. Arg. I. c. T. cannabina, Linn. 

 Suppl. 415 ; A. Juss. Tent. Euphorb. t. 15, 49 B ; Wall. Cat. 7715. T. hispida, 

 Herb. Russell. Croton hastatus & urens, Linn. Syst. Ed. 13, 722. 



2. T. bicolor, Miquel in Linncea (1853) 22, and Plant. Hohenack. 

 No. 1552 ; branches villously hirsute, leaves shortly petioled ovate-cordate 

 acuminate serrate tomentose on both surfaces, racemes rather stout, bracts 

 very long lanceolate, feni. sepals strisrose entire, capsule tomentose and setose. 

 T. Miqueliana, var. bicolor, Muell. Arg. in DC. Prodr. xv. ii. 943 (excl. Melz. 

 No. 755). 



NILGHIRI HILLS, Wight, &c. ; at Conoor, alt. 5000 ft., Clarke. 



Resembles some tomentose forms of 2'. involucrata, but the bracts of the racemes 

 are fully in. long, the flowers larger, the fruiting calyx much smaller, in. diam., 

 the sepals entire, hirsute within, and wanting the rigid woody midrib. It is a moun- 

 tain plant, often but not always pulverously or rustily villous when dry. Mueller's 

 T. Miqueliana var. bicolor consists of this, and of Hohenacker's No. 755, which is a 

 native of Canara (not as Mueller supposes, the Nilghiris), and which is T. involucrata.
