578 cxi. VERBENACE^;. (C. B. Clarke.) [Premna. 



Roxburgh grounds his species on the cordate base of the leaves : this form appears 

 confined to the Coromandel Hiils. 



VAR. cuneafa; leaf-base rhomboid or cuneate, calyx strigose. P. viburnoides, 

 Kurz For. Fl. ii. 261. Pegu ; Kurz. Burma; Griffith (Kew Distrib. n. 6035). A 

 small tree of the dusky sombre colour of P. latifolia Roxb. type, the leaves drying 

 blue-black above, ashy beneath, often very pubescent when young. 



VAB. mollissima ; leaves small base obtuse or rhomboid, corymbs 1| in. diam. 

 P. molHssima, Roth Nov. Sp. 287; Schauer in DC. Prodr. xi. 638. P. viburnoides, 

 Wall. Cat. 2646, letter a only ; Schauer I. c. 635, chiefly. Madras ; Wight. This 

 looks like a burnt-up form of Var. cuneata, than which it is not more hairy, but 

 has smaller calyx and corolla. 



VAR. mucronata ; leaves cuneate at both ends mature minutely pubescent on 

 the midrib beneath, corymbs somewhat broad rusty-pubescent, calyx subpatently 

 pubescent. P. mucronata, Eoxb. Fl. Ind. iii. 635 ; Wall. Cat. 1766 ; Schauer in 

 DC. Prodr. xi. 635 ; Brand. For. Fl. 366. N. India from Kumaon to Bhotan and 

 the Khasia Mts., ascending to 5000 ft, and spreading into Bengal Plain, common, 

 Wallich, H.f. fy T., &c. This could not be distinguished from P. latifolia by Wallich 

 or Brandis, and seems to be a state of P. latifolia grown in a moister soil. The 

 leaves are often 6 in. long, the drupes larger and more verrucose. 



VAR. viburnoides, Wall. Cat. 2646, letter b only ; leaves ovate base rhomboid 

 glabrate drying green surfaces concolorous. Schauer in DC. Prodr. xi. 635, in sm ill 

 part. P. latifolia, Wight Ic. t. 869. S. Deccan Peninsula ; Cochin and Gingee Hills, 

 Wight near Madras, G. Thomson. Leaves broad, not cordate, nearly glabrous even 

 when young. This may be a distinct species ; the green colour easily separates it from 

 all the preceding forms of P. latifolia. 



23. P. flavescens, Ham. ; Wall. Cat. 2649 ; leaves ovate or obovate 

 acuminate entire mature setulose above villous beneath., corymbs large 

 densely pubescent, calyx closely pubescent shortly 5-toothed. 



. BENGAL; Goal para, Hamilton Dacca, Clarke. 



A shrub or a small tree; shoots villous or woolly. Leaves 6 by 2J in., base obtuse 

 or subcordate, upper surface with minute scattered hairs erect from the reticulating 

 nerves; nerves 7 pair; petiole 1 in. Corymbs 4-7 in. diam., usually rusty-villous ; 

 bracts in., linear. Calyx -jj in. Corolla | in., 2-lipped, very hairy below within. 

 Drupe 1 in. 



VAR. glabrior ; leaves setulose above sparingly pubescent or glabrate beneath 

 green. Premna n. 24, Herb. Ind. Or. H.f. & T. Subtropical Sikkim, alt. 3000 ft., 

 Clarke. Silhet ; H.f. $ T. 



VAR. rubens ; leaves setulose above glabrate beneath drving usually reddish. 

 Premna n. 32, Herb. Ind. Or. H.f. $ I 7 . Malacca; Griffith (Kew Distrib. n. 6020 . 

 (Java.) Possibly a distinct species ; but, except as to the colour of the leaves, no 

 diagnostic mark has been found to separate it from Var. glabrior. 



24 P. micrantha, Schauer in DC. Prodr. xi. 635; leaves ovate 

 acuminate entire mature setulose above somewhat pubescent beneath, 

 corymbs compound minutely pubescent, calyx very small minutely 5-toothed. 

 P. scandens, Wall. Cat. 1774, in small part. 



SILHET; Wallich. 



Leaves 3 \ by If in., base rounded. Calyx 5',-^ in- when the flower is expanded. 

 This very closely resembles P.flavescens, Ham., and may be a form of it ; it differs in 

 the very small calyx. The bristliuess of the upper surface of the leaves is peculiar to 

 P.flavescens and P. micrantha among Premnas. 



25. P. Wig-htiana, Schauer in DC. Prodr. xi. 635; leaves ovate 

 shortly acuminate subentire mature sparsely pubescent above, panicles 

 narrow subthyrsoid in fruit minutely thinly scabrid-pubescent, calyx-teeth 

 5 subequal ovate or triangular. P. thyrsiflora, Heyne; Wall. Cat. 1770.
