HYDROPHYL'LUM, J. [from tX ? , Gr. water, and 
(pvAAon, a leaf.] Water-leaf ; in botany, a genus of the 
clafs pent'andria, order monogynia, natural order of bor- 
raginea;, Jvjf. The generic characters are—Calyx: peri- 
anthium five-parted, fcarcely fhorter than the corolla, 
fpreading, permanent, with awl-fi>aptd fegments. Co¬ 
rolla: one-petalied, bell-fhaped, five-cleft; fegments up¬ 
right, obtufe, emarginate. Neftary, a cleft clofed by two 
longitudinal converging plates, fattened to the petal with¬ 
in the.maiddle of each fegment. Stamina : filaments five, 
avri-fiiaped, longer than the corolla; antberae incumbent, 
oblong. Pidillum : germ fuperior, ovate, acuminate ; 
ftyle awl-fiiaped, the length of the llaraens; itigma bifid, 
acute, fpreading. Pericarpium : capfuie globular, one- 
celled, two-valved. Seed : fingle, round, large; (feeds 
four, nefiling within a berried receptacle, Gartner.)—EJJ'cn- 
tial CharaEler. Corolla bed-fiiaped, having five longitu¬ 
dinal melliferous breaks on the infide ; itigma bifid ; cap¬ 
fuie globular, two valved. 
Species, i. Hydrophyllum Virginicum, or Virginian 
water-leaf: leaves pinnatifid. The root is competed of 
many itrong flefhy fibres, which fpread wide on every 
fide ; from this arife many leaves on foot-dalks five or fix 
inches long, jagged into three, five, or (even, lobes, al- 
moft to the midrib; they are indented on their edges, 
have feveral veins running from the midrib to the fides, 
and are of a lucid green. The flowers rife with foot-dalks 
from the root, having one or two fmall leaves of the fame 
(liape with the lower; they are in loofe clufters hanging 
down, of a dirty white, and making no great figure. Cap¬ 
fuie marked on each fide with a (hallow-groove, and fprin- 
kled all over with fmall white bridles. Receptacle glo¬ 
bular, free, filling the whole cavity of the capfuie, at fil’d 
herbaceous and flefhy, divided into little cells equal in 
number wdth the nafeent germs, afterwards membrana¬ 
ceous and fpongy, rufefeent, fplitting in two with the 
capfuie. Seeds regularly four, but often fewer, nedling 
in the receptacle, irregularly ovate and angular, elegantly 
•netted with very minute excavations, yellowifh white. It 
flowers here in May and June, and the feeds fometimes 
ripen in Augufl. Native of Virginia and Carolina, on 
moift fpongy ground. It was cultivated in 1739, by Mr. 
Miller. Pie fuppofes that Morinus gave it. the title of wa¬ 
ter-leaf becaufe in fpring water (lands in the cavities of 
the leaf, and not from its growing in water, as Tourne- 
fort conjectures. 
i. Hydrophyllum Canadenfe, or Canadian water-leaf: 
leaves lobate-angular. This has all the fame druClure 
with the preceding, and differs only in the leaves, whith 
have the fame (hape with thofe of the maple, half-five- 
lobed, fmooth, with the lobes acute, (lightly toothed, and 
having a finus at the petiole, as in the leaves of maple. 
Native of Canada. It flowers in May. 
Propagation and-Culture. Thefe plants are very hardy in 
refpeCt to cold, but they (hould be planted in a moill, 
rich, foil, and fnady fituation; in a warm dry foil they 
will not profper, unlefs they be condantly watered in dry 
weather. They may be increaled by parting the roots in 
autumn; for, if they are not well-rooted before fpring, 
they will require abundance of water. See Hydrastis.
