DIAND. MONOG. 9 



Roots much branched. Stems prostrate in the water. Leaves capillaiy, 

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

 Scape erect, 4 6 inches high, 6 8-flowered. Flowers in a raceme, 

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

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

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

 those of Pinguicula. Stigma large, plain, roundish. Cops, globose. 



2. U. intermedia (intermediate hooded Milfoil) > spur conical, 

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

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



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

 four miles east of Forfar, D. Don. Probably in a marsh at Fossil 

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

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

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

 Fl. June, July. )/ . 



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 vesicles 

 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. Lightf. p, 78, 

 E. B. t. 254. 



HAB. Ditches and pools, rare. Coryattachan in Skie, Lightf. Turf- 

 pits, east side of Black Loch, Kirkmichael, Dumfries-shire, Dr. Bur- 

 gess. Loch near Kilpatrick, Hopk. Peat-pits, Ravelrig-toll, Edinb., 

 Mangh. Fl. June, July. 3/ . 



Still smaller than the last. Vesicles mixed with the leaves. Leaves 

 glabrous at the margin. Flowers 5 6, very pale yellow. Spur 

 scarcely any. Lower lip almost plane, palate rather smaller, not 

 closing the mouth, equal in length to the upper lip. 



7. LYCOPUS. 



1. L. eitrop&us (Heater Horehound), leaves deeply sinuato- ser- 

 rate. Lightf. p. 79. E. B. t. 1105. 



HAB. Ditches and river-banks (not in Fl. Glott.) . Margins of Loch 

 of Lindore, Fifeshire, D.Don. In Arran; Delvine, Perthshire, 

 Mr. Murray. Fl. June, July. I/. 



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

 Ord. Gymnosp. (Labiatce Juss.), 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, 

 ] miry within,
