DOCBTFCL SPECIES. 



H. EoxBUEGHii, Spreng. Syst. curts post. 54 ; erect, ramous, hairy, leaves petioled 

 ovate-oblong, spikes terminal panicled seound, tube of the corolla long and gibbous. 

 DC. Prodr. ix. 649. H. panionlatum, Boxb. Fl. Ind. ed. Carey ^ Wall. ii. 2, not of B. 

 Br. — Chittagong, Boxbwrgh. Known only from Eoxburgh's description. Possibly, 

 as Eoxburgh did not live to publish his own mss., this was his first description of 

 Tourmfortia Boxburghii (afterwards described fully under Lithospermum), which he 

 may have preserved for reference. This explanation applies certainly to some dupli- 

 cate species in Roxburgh's posthumous work. It can hardly be S. zeyla/nicvm, Lamk. 

 (as Bottler supposed) because that species is not known in Chittagong. 



7. TRICKODESniA, Br. 



Coarse, hispid herbs. Leaves opposite, upper alternate, entire. Pedicels , 

 axillary, 1-flowered, going off into terminal racemes by the gradual reduction of 

 the floral leaves. Calyx deeply 5-merous ; lobes triangular-lanceolate, in fruit 

 enlarged. Corolla-tube campanulatercylindrie, throat without scales ; lobes 5,. 

 twisted to the left, a gland or depression near the base of each. Stamens 5, 

 filaments short ; anthers elongate, lanceolate, connivent in a cone ; connectives 

 more or less hairy on the back, tips excurrent at length twisted. Ovary 4-oelled ;, 

 style terminal filiform, stigma small. Fruit ellipsoid, sub-4-ridge(i ; nutlets 

 ovoid-oblong, smooth, shining on the back, scabrous, slightly or strongly mar- 

 gined on the inner face, closely adnate by their whole inner face to the carpo- 

 phore below the style, finally separating. — Species 10 ; in tropical and warm- 

 temperate Africa, Asia, and Australia. 



* Calyx-lobes in fruit cordate or hastate at the base. 



1. T. indicum, Br. Prodr. 496 ; bristly with hairs springing from 

 tubercles and also more or less viUous, leaves mostly sessile lanceolate or cordate- 

 lanceolate, calyx-lobes (at least in fruit) cordate or hastate at the base, stamina! 

 cone densely closely woolly on the back. Wall. Cat. 932 ; Wight III. t. 172 ;

Throughout India ; common ; not in Bengal Plain. — Disteib. Cabul, Beloochistan, 

 Persia, Mauritius. 



Erect or diffuse. Leaves 1-4 in., tuberculate on the upper surface, liower pedicels- 

 often distinctly axillary, 1-flowered. Calyx-lobes ^-^ in., more or less grey- or white- 

 villous. Corolla-tube ^ in. ; lobes ^ in., ovate, suddenly acuminate. Nutlets ^ in., 

 sometimes very rough on the inner face, obscurely margined. — ^Edgeworth notes that 

 Borago spimdosa is Trichodesma indicum, probably correctly; no one appears to have 

 seen a specimen or to know what else it can be. 



Vae. subsessilis ; leaves subelliptic narrowed downwards many very shortly 

 petioled. T. subsessilis, WaSl. Cat. 933. — British Burma ; Prome, WalUch ; Pegu,
