N.B. Varrónia móllis, Desf. tabl. de jard. par p. 220. is a

Orver CLXVIII. HYDROPHY'LLE Æ (this order contains 
plants agreeing with the genus Hydrophijllum in important cha- 
racters.) R. Br. in bot. mag. vol. 50. t. 2373. append. to 
Frankl. journ. Benth. in Lin. trans. 17. p. 267. 
sect. II. Juss. gen. 129. ed. Usteri, p. 144. 
Calyx inferior, permanent, deeply 5-cleft; the recesses be- 
tween the segments often furnished with reflexed appen- 
dages. Corolla monopetalous, hypogynous, regular, shortly 
5-cleft, rotately campanulate, rarely somewhat funnel-shaped. 
Stamens 5, perigynous, alternating with the lobes of the 
corolla, inflexed in estivation; anthers versatile, 2-celled ; 
cells parallel, dehiscing lengthwise. Ovarium superior, sim- 
ple, 1-celled. Style elongated, bifid; stigmas 2, terminal. 
Plaeentas 2, free to the back, or adnate to the parietes of 
the fruit; their inner surface bearing 2 or many ovula. Fruit 
capsular, dehiscing by 2 valves; sometimes 1-celled, from the 
large placentas filling the capsule; but sometimes the dissepi- 
ment is hardly complete, therefore the capsule is half 2-celled. 
Seeds reticulated outside. Albumen copious, cartilaginous. 
Embryo conical, with the radicle looking to the hilum.—Elegant 
herbs, natives of America; hispid, like those of Boraginee. 
Leaves usually lobed, alternate, or the lower ones are opposite. 
Flowers disposed in unilateral, subdichotomous spikes or ra- 
cemes, which are at first circinately scorpioid; rarely axillary, 
solitary, pedunculate. Corollas blue or pink, elegant. 
This order is distinguished from Boraginee, and its nearest 
allies, by the capsular fruit, copious, cartilaginous albumen, pla- 
centation of the seeds, and generally by the compound, or deeply 
lobed leaves.

I. HYDROPHY'LLUM (from idwp bdaroc, hydor hydatos, 
water ; and $vAXov, phyllon, a leaf. Miller supposes that Mo-

stands in the cavity of the leaves, and not from its growing 
in water, as Tournefort conjectures.) Tourn. inst. t. 16. Lin.
