with connective prodviced into a long acumen. Style minute, 

 swelling large with bluntly conical stigma about as long as the style. 

 Nutlets dark grey-brown, acute, "06", hispid above.

6. TRICHODESMA, Br. 



Coarse hispid herbs with the lower leaves opposite, hairs with 

 usually cystolith- celled bases. Flowers m.s. 5-merous solitary axil- 

 lary and running into terminal racemiform unilateral cymes. Calyx 

 deeply lobed or partite, lobes accrescent in fruit. Corolla salver- 

 shaped with broad tube or campanulate, throat naked, lobes over- 

 lapping to the left, a gland or depression near the base. Stamens 

 with shoi^t filaments and lanceolate anthers connivent in a cone, con- 

 nectives more or less hairy on the back, excurrent, at length twisted. 

 Ovary 4-celled, style terminal, filiform with small stigma. Fruit 

 ellipsoid or pyramidal, finally separating into nutlets closely adnate 

 by their inner face to the 4-winged carpophore or conical torus, 

 sometimes margined. 

 Ridges from the calyx-sinuses produced downwards into auricles. 



Corolla over '6" diam. with distinct lobes 1. indicum. 



Calyx rounded at the base, without auricles. Corolla under -6' 



diam., lobes not prominent (exc. the twisted tip) . . . .2. zeylanicum. 



1. T. indicum, R. Br. Hetmudia, S. ; Hetamundia, Or. 



A much-branched diffuse hispid herb 8-18" high with sessile 

 usually sub-sagittate or cordate based linear, oblong, lanceolate, or

 brown throat, usually over "6" diam. often 1", in leafy or few-fid. 

 cymes. Calyx -^--e" long, hispid-hairy, lobes lanceolate, margins 

 strongly ribbed and subalate at the connivent bases and produced 

 dowuAvards into a distinct auricle or spur. Cor. -lobes ovate, suddenly 

 narrowed to a fine twisted tip. Nutlets white smooth with polished 

 back, scarcely margined, •l7-"2* long, ell. -oblong. 



Frequent ! Behar, Hope ! Santal P. ! Throughout Chota Nagpur ascending to 

 Neterhat, 3000 ft. ! Angul, Chattarjee ! Probably, therefore, in all districts. Fl, 

 Sept.-Jan. and perhaps at other times. FL, Fr. most of the year. Annual.

 or extra- axillary often 2" in fruit. Base of cor. -lobes with brown glands. 



2. T. zeylanicum, R. Br. Same vernacular names. 



An erect herb 2-4 ft. high, very bristly below, more hairy towards 

 the inflorescence. Leaves : lower petioled, often oblanceolate and up 

 to 6'5", upper sessile, oblong or lanceolate-oblong, smaller upwai-ds 

 and passing into bracts. Flowers pale blue, usually about "4" diam. 

 only, \iltimately very numerous running out into bracteate racemes 

 2-5" long, the whole top of the plant becoming a large panicle Avith 

 leaves at the forks. Calyx with lanceolate or ovate-lanceolate lobes 

 often overtopping the corolla, margins conniving below but marginal 

 ridges not produced at the base into spurs or auricles. Corolla
