1. M. minimus (L.). — E. J3.435. R.45G9. — St. simj)le, leafless, 
single-flowered, 2 — 5 in. high. Recejitaele very long, v\ith nu- 
merous oblong cari)els. L. linear. The seed being attached to 
the ujjper part of the carp, makes it j)cndulous with the radicle 
pointing upwards; this dilference from the true Ranunculi is 
only ap])arcnt, and is caused by the singular point of attachment 
of the seed, the radicle being in fact inferior. — In damp places

confounded under this name, viz. B. heterophyllus (Fries) ; floating

or floating leaves; or B. peltatus (Fries); floating 1. subpeltate 
with a cordate or truncate base and crenate lobes, fl. from the 
axils of the floating 1. alone. Often the floating 1. are wanting 
in the former ; never in fertile plants of the latter. — Ponds and 
ditches. P. V. VI. Water Crowfoot.
