blunt, three-cloven, lobed ; those of the stem spear-shaped, very 
entire : stem with one flower. 
Jacq. Austr. 110— E. Bot. 2390. 
( Plant four or five inches high, erect, smooth in every part. Leaves chiefly 
radical, veined. Flower large. E.) Petals inversely heart-shaped, of a 
brilliant white. Calyx smooth, bordered with white. Stem-leaf often ter- 
nate; the radical ones greatly resemble those of R. aquatilis that float on 
the surface, and in watery places may be mistaken for them. Linn. Tr.

Alpine White Crowfoot. Discovered by the sides of little rills, and in 
other moist places about two or three rocks on the mountain of Clova, 
Angus-shire, very rare, and but seldom flowering, by Mr. Don, who sug¬ 
gests that its herbage, bearing a great resemblance to several of its kin¬ 
dred, may easily have been overlooked, but when in blossom it is truly 
an attractive plant. P. May. E.) 
R. aquat'ilis. (Stem floating, submersed : leaves hair-like; those 
above somewhat peltate, lobed, notched, with nearly central 
leaf-stalks. E.)

Flowers on fruit-stalks which arise from the same sheath with the leaves. 
Petals white, with a yellow spot at the base. Nectary a short open tube. 
(Stems cylindrical, leafy, lengthened branched out, according to the depth 
of water. Plant often covering the surface in extensive dense masses, 
with a profusion of flowers. E.) 
Var. 2. Large-jlowered. None of the leaves hair-like; flowers very large. 
In a pool that had been a quarry, near Sodbury, Gloucestershire. Rev.

Var. 3. Circinatus. All the leaves hair-like, forming a roundish line.

* This is a troublesome weed in ponds, but its flowers produce a beautiful effect when in 
such profusion as to cover the whole surface of the water. The varieties in the leaves seem 
entirely occasioned by the greater or less depth of the water, and by its being stagnant or 
not, and are therefore by no means constant. (Mr. Thomson remarks that in plants even 
not aquatics, but which happen to be planted in water, we may perceive the metamor-
