DIAND. — MONOG. 9 



Roots mucli branched. Stems prostrate in tlie water. Leaves capillary, 

 multifid with minute bristles at the margin, mixed with the vesicles. 

 Scape erect, 4 — (i inches high, 6 — 8-flowered. Flou-ers in a raceme, 

 large, bright yellow. Lower Up convex, much larger and broader 

 than the upper one, and having a very projecting palate closing the 

 mouth. Spur bent down, short. Anthers curved, thick, resembling 

 those of Pinguicula. Sligma large, plain, roundish. Caps, globose. 



2. U. hUermedia {intermediate hooded Milfoil) y spur conical, 

 upper lip twice as long as the palate, leaves tripartite their 

 segments linear dichotomous. E. B. t. 2489. 



Hab. Ditches and deep pools. In a ditch by the side of Rescalin Lake, 

 four miles east of Forfor, D. Bon. Probably in a marsh at Possil 

 ami Robroyston, Glasgow, Hopk., since that gentleman found upon 

 the plants there little green balls or bulbs, the germs of future in- 

 dividualo, a mode of propagation considered peculiar to this species.

It is smaller than U. vulgaris, the flowers are of a paler colour, and 

 have a longer upper lip. The stems are more leafy, and the vesicle:: 

 grow distinct from the leaves. The latter are broader, linear, tri- 

 partite, with the segments again di- trichotomous, the margins 

 bristly. 



3. U. minor (lesser hooded Milfoil), spur extremely short ob- 

 tuse keeled upper lip as long as the palate, leaves subtri- 

 partite the segments linear dichotomous. Lighlf. p. 78.

Stems two feet, erect, four-sided, as in all the Class Didynamia and 

 Ord. Gymnosp. {Labiatce J uss.), to which very natural family this and 

 the following genus belong, though placed here in consequence of 

 their having but two stamens. Leaves opposite, nearly sessile, 

 large, ovato-lanceolate, rugose, very deeply sinuato-serrate, almost 

 pinnatifid, especially the lower ones. Flowers sessile, in dense 

 whorls at the base of the superior leaves, whitish with purple dots,
