sepals cuneate to cuneate-oblong, obtuse, free, glabrous, fuscous ; 
petals small, broadly oblong, with a dark short linear gland just 
below the shortly hairy apex; stamens 6, anthers dark. 
Plants 8 to 16 in. high, flowering somewhat rarely. Long 
flattened stolons which root and produce new plants at the end, 
radiate from the centre of the leaf-rosette, and are sheathed like 
the scapes. Leaves laxly spreading, reaching nearly 9 in. in 
length, with } to 2 line greatest breadth. Scapes to 16 in, 
long, sheaths to 33 in., flower-heads 3 to 4 lines across ; 
involucral bracts 14 to 12 by 1 or scarcely 1 line; floral bracts 
14 by i line or narrower. Stalk of female flower } line long; 
sepals 1 by 4 to 2 line; petals 1 to 14 by 3 line; stalk of male 
flower 3 line; sepals 1 line, or a little more, by } line; pedestal 
above calyx 2 line long ; petals $ by 4 to nearly 3 line. 
Near LH. rivulare Don, but distinguished by its narrow leaves, 
larger flowers with glabrous sepals, etc. 
Huiiia.—A perennial entirely submerged herb, with flower-heads 
just emerging when mature. Plentiful in cold rather rapidly flowing

Forms a widely spreading very green carpet beneath the water. A
