CENTRAL and EASTERN HIMALAYA ; Nepal Morung, Hamilton. SIKKIM, alt. 2000 ft., 

 Clarke. 



Stem stout. Leaves 4-6 in. long and nearly as broad, pubescent or glabrate 

 above ; petiole 1^-3 in., slender. Cymes shortly peduncled, 3 in. diam. Corolla-tube 

 cylindric, in. long ; lobes spreading and recurved, thick. Column nearly filling the 

 tube. 



11. M. thyrsiflora, Hook.f.; nearly glabrous except the puberulous 

 cymes, leaves broadly ovate or oblong- or deltoid-ovate deeply cordate acumi- 

 nate, cymes elongate of clusters of shortly peduncled flowers on a long rachis, 

 corolla urceolate glabrous without and within, lobes lanceolate, coronal scales 

 short rounded wholly adnate to the long subulate anther-tips. M. tinctoria, in 

 part, Herb. H.f. $ T. 



BENGAL ; in the Jheels, Griffith, J. D. H. $ T. T. ASSAM, Masters. 



Leaves 4-8 by 2-6 in., membranous ; petiole 1-3 in. Cymes 4-6 in. long; rachis 

 flexuous ; pedicels very short. Sepals nearly glabrous, obtuse. Corolla jj^-^j in. 

 long ; lobes coriaceous. Anther-tips longer than the column, basal spurs very small. 

 Stigma fusiform. Follicles 2 in. long, dagger-shaped, turgid below ; pericarp thinly 

 coriaceous, glabrous. Seeds ovate, -|- in. long. So similar to some forms of M. 

 tinctoria in foliage and inflorescence as to be easily mistaken for that plant. The 

 coronal scales may be said to be absent.

M. ROTUNDIFOLIA, Dene, in DC. Prodr. viii. 615 ; " branches thick glabrous ; leaves 

 rounded, obsoletely cordate, glabrous, shortly acuminate ; petiole rather long, slender, 

 puberulous ; cymes subcontracted, many-fld. ; peduncle equalling the petiole ; corolla- 

 lobes ovate-oblong, densely bearded within ; coronal scales ovate-deltoid, equalling 

 the column." Communicated from the Calcutta Garden to Paris Herb, by Griffith. 



33. PERGULARIA, Linn. 



Twining subglabrous undershrubs. Leaves opposite, ovate-cordate, mem- 

 branous. Cymes subumbelliform. flowers greenish or yellow, rather large. 

 Calyx 5-partite. Corolla salver-shaped, tube swollen at the base ; lobes oblong 

 or linear, overlapping to the right Column rather large ; coronal scales large, 

 membranous, adnate to the back of the anthers, erect, flattened dorsally or 

 laterally, acute, simple or transversely bifid (2-lamellate above the middle), 

 pollen-masses one in each cell, subcylindric clavate or globosely obovoid, waxy,
