rhomboideo-cordatis, subacutis, rugosis, subtus praecipue pubescenti- 

 bus, crenato-serratis ; racemis terminalibus, solitariis, verticillalis, 

 subcapitatis ; corollse labio inferiore ampliato, patente, bilobato. Sta- 

 minibus longe exsertis. Bracteis ovatis, acyminatis, deciduis.

 Description — Stem herbaceous, branched, 4-sided, pubescent ; hairs short 

 recurved, and most numerous in two broad lines along two sides, alter- 

 nating at the joints ; hairs with several joints. Branches green, spread- 

 ing. Leaves petioled, veined, rugose, subacute, pubescent on both sides, 

 but especially' on the under, crenato-serrated, the serratures mucronu- 

 late, in the more luxuriant plants (which are IJ foot high, I^ across) of 

 dark green, the larger ones (4 inches long, 3i broad) being subrhoniboi- 

 deo-cordate, and often unequal at the base, in the smaller plants (where 

 they are li inch long, and rather more than 1 inch broad,) pale green and 

 cordate. Petioles spreading, channelled, ciliated, shorter upwards. Ra- 

 cemes terminal, solitary, verticillate ; peduncle without flowers for a con- 

 siderable way above its origin, and resembling the stem in shape and the 

 bifarious arrangement of its hairs ; verticels 2-C. flowered, according to 

 the luxuriance of the plant, collected into a lax capitulum ; pedicels 

 slightly hairy, spreading on all sides. Calyj; with three mucronate erect 

 teeth, and eleven primai-y nerves, three running along each of the lower 

 teeth, and five along the upper, hairy, especially along the ribs, and 

 sprinkled, as well as the stem, and both sides of the leaves, but more 

 abundantly, than these, with minute, shining, subviscid glands ; tube 

 subcylindrical ; limb, after the corolla falls compressed laterally, closing 

 the throat. Corolla azure-blue, the tube only and two parallel linear 

 streaks in the centre of the lower lip being white ; tube glabrous, nearly 

 filling the calyx, and equal to it in length, compressed laterallv, curved ; 

 •limb pubescent on the outside, upper lip shorter than the tube, nearly 

 straight, lower lip spreading, twice as long as the upper, 4-lobed, lobes 

 obtuse, spreading. Stamens closely enveloped by the upper lip, but 

 double its length ; filaments smooth, rather paler than the corolla ; an- 

 thers darker, bursting along their lower sides, pollen yellow. Style simi- 

 lar to the filaments, but more slender, and rather shorter, bifid at the 

 apex, the lower segment revolute, and, by much the broadest and longest, 

 the stigmatic surfiice being arranged along its edges, and awanting alto- 

 gether on the small, subulate, upper segment. Lohcs of the germen pale 

 yellow, obovate, slightly mutually impressed, veined, obscurely dotted, 

 placed around the base of the style on a large fleshy yellowish-white 

 receptax:le. 

 The plant was raised from seed communicated by my valuable correspon- 

 dent IVIr Cruckshanks from Lima this season, and flowered in the stove 

 of the Botanic Garden in ]May and June. 

 I do not hesitate to refer this species to S. rhombifolia of Ruiz and Pavon, 

 though the upper leaves are less sessile than in their figure, the branches 

 and calyx always green, the peduncles alwaj'S solitary in our specimens, 

 which are in every degree of luxuriance, and the verticels fewer and 

 more capitate.

Descriptiok' Bienni.d ? Stem herbaceous, stout, branched. Branches 



ditfused, whole surface covered witli glandular pubescence. Leaves va^. 

 riable, once or twice pinnatifid, laciniae incised. Pedicels (|thsof an inch 

 long) both in flower and in fruit secund, erect. Flowers in large branch.
