ORDER CLXVIII. HYDROPHY'LLE^ (this order contains 



plants agreeing with the genus Hydrophyllum in important cha- 

 racters.) R. Br. in hot. mag. vol. 50. t. 2373. append, to 

 Frankl. journ. Benth. in Lin. trans. 17. p. 267. Boraginee, 

 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 asstivation ; anthers versatile, 2-celled ; 

 cells parallel, dehiscing lengthwise. Ovarium superior, sim- 

 ple, 1 -celled. Style elongated, bifid ; stigmas 2, terminal. 

 Placentas 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 Boragineae. 

 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 Boraginece, 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 icp Ifarof, hydor hydatot, 

 water ; and ^uXXoi', phyllon, a leaf. Miller supposes that Mo- 

 rinus gave it the name of Water-leaf, because the spring water 

 stands in the cavity of the leaves, and not from its growing 

 in water, as Tournefort conjectures.) Tourn. inst. t. 16. Lin.
