obovate, slightly furrowed, rose coloured, trilocular. Ovules very nu- 

 merous, smdl, attached to the central column. 

 The species is a native of BraziL We received our specimen from the 

 rich collection in the Botanic Garden at Liverpool In October last. It 

 produced its handsome spike in the stove of the Botanic Grarden, Edin-

Stenochilus viscosus. 



S. viscosus ; foliis ovato-lanceolatis, serratis, postice integerrimis, ramu- 



lisque nitidis viscosis, iloribus axillaribus solitariis. 



Descriptiok — Shrub erect, bark brown and smooth ; young branches sub- 



angular, scabrous, glutinous, green. Leaves (IJ inch long) scattered, 



ovato-lanceolate, subacute, conaceous, rigid, suberect, slightly concave, 



glutinous, shining, bluntly and distantly tooth-serrated in their upper 

 alf, entire behind, obscurely and sparsely veined, middle rib blunt and 

 slightly prominent behind. Flowers solitary, axillary, collected towards 

 the extremities of the shoots, longer than the leaves. Peduncles (3 lines 

 long) green, filiform. Calyx (halfan inch long) green, 6-cleft, segments 

 subulate, glutinous within and without, the upper broadest and longest, 

 the two lateral shorter and narrower than those below. Corolla (above 

 an inch long) yellow, ringent, curved, pubescent both within and without, 

 and the hairs distilling from their extremities a viscid colourless fluid, bi- 

 labiate ; upper lip very broad, and folded down by the sides of the flower, 

 4-toothed, teeth subulate, those at the side reflected and their apexes 

 approaching behind the two in the centre, which are erect, with their 

 apexes somewhat spreading ; lower lip much more narrow, linear, en- 

 tire, blunt, revolute ; tube inflated at its base, nectariferous. Stamens 

 didynamous, arising from the inflated portion of the tube, exserted (pro- 

 jecting half an incn beyond the corolla) ; filaments thread-like, nearly 

 straight, yellow, inserted into the back of the anthers ; anthers oblong, 

 bilobular, with a rounded continuous border, lobes bursting in front ; 

 pollen yellow. Stigma minute, blunt, cleft, greenish. Style purjple, fi- 

 liform, (44 lines) longer than the stamens, over which it is curved. Ger- 

 men ovate, slightly flattened, yellow, greenish towards its apex. 

 The species is a native of New Holland, from whence seeds were imported 

 by F. Henchman, Esq. and plants raised by Mr Mackay in his nursery 

 at Clapton, along with m^y other additions to our greenhouses from the |" 

 same quarter. The specimen above described was kindly communi- 

 cated by him to the Royal Botanic Garden, Edinburgh, in October last. 

 It flowered in the beginning of March.

T. crassula ; caule ascendente, radicante, ramoso, glabro ; foliis vaginan- 

 tibus, oblongo-lanceolatis, utrinque nitidis, glaberrimis, intf^rriuiis, 

 nervosis, vaginisque adpressis ciUatis ; umbUlis simplicibus, axillari- 

 bus terminaUbusque, pedunculatis sessilibusque, subsolitariis, pedun- 

 culis angulatis, pedicellisque nitidis ; filamentis basi lanatis. 

 Description.— iS^eTO (3 feet long) stout, succulent, iiscending, rooting at 

 the joints, smooth and shining, green, occasionally purple, especially at

 leafets, resembling the ordinary leaves of the plant ; peduncUs{\-',\ inches 

 long) angular, straight, smooth and shining ; pedicels (fully halfan inch 

 long) like the peduncles, but reflected when the flower has faded. Caiyjt
