BORAGINEjE. 477 



1. HYDROLEA, L. 



Calyx 5-partite. Corolla rotate. Stamens exserted. Capsule 2(-3)-celled; margiuicide . 

 valves seceding from the entire dissepiment: placentas central, thickish. — Flowers blue, 

 racemose, oblique in the axils of the bracts. 



1. H. spinosa, L. Shrubby, glandular-pilose ; leaves elliptical -lanceolate or lanceolate, 

 repand-entire : axils beariug usually a pubescent spine : racemes usually short, compound -, 

 corolla-segments elliptical, shortly exceeding the calyx ; capsule ovoid-globose, glabreseent, 

 2-3-celled. — Aubl. t. 110. — H. trigyna, Sw. — 4' high ; corolla fragrant, 8'" diam* — Hab. 

 Jamaica !, Pd., Dist., Wullschl., rare in swamps and floating islands, S. Elizabeth, Man- 

 chester ; Dominica I, Imr., S. Vincent !, Guild. ; Trinidad !, Lockh., Or., in moist savan- 

 nahs ; [Mexico ! to Brazil !]. 



2. NAMA, L. 



Calyx 5-partite. Corolla infundibular. Stamens included. Capsule medianicide, at 

 length 4-valved by the valves seceding from the placentas : placentas 2, parietal, contiguous 

 in the axis : seeds dorsal on their revolute margin. — Herbs ; flowers obliquely deflexed, 

 fascicled in the axils and between the branches, rarely cymose. 



2. W. jamaicensis, L. Annual, procumbent, hispidulous ; leaves obovatc, contracted 

 at the base, decurrent, entire; pedicels shorter than the calyx, fascicled (-single) ; calyx- 

 segments linear-acuminate, shortly exceeded by the white, tubular-infuudibalar corolla, 

 including the oblong-linear capsule. — Br. Jam. t. 18. f. 2. — Calyx 4'" long. — Hab. Ja- 

 maica !, Bancr., Al., a weed ; [Cuba !, Haiti ! ; Texas !, Mexico !]. 



3. WIGANDIA, Kth. 



Calyx 5-partite. ■ Corolla rotate. Stamens exserted. Capsule medianicide, 2-valved : 

 placentas 2, parietal, adhering to the middle line of the valves, contiguous in the axis, the 

 revolute margins entirely covered with seeds. — Hispid, large-leaved herbs ; flowers in gy- 

 rate, 2-bracteate, branched, spiciform racemes. 



This genus, by its inflorescence, approaches Hydrophyllea, from which it is distinguished 

 by its 2, distinct styles. 



3. W. urens, Kth. Leaves ovate, blunt, subcordate at the base, duplicate crenate or 

 minutely lobed, scabrous-pubescent above, villous beneath; panicle hispid : flowers 2-seria I 

 along its conjugate branches ; calyx-segments linear, equalling the corolla-tube, including 

 the ovoid, hispid capsule— R. P. Fl. Peruv. t. 243. Bot. Mag. t. 4575.— Hydrolea, R. P. 

 W. Kunthii, Chois. W. caracasana, Hook. ! — Corolla l"diam. — Hab. Trinidad !, Pd., Cr., 

 in arid places, on the island of Monos; [Mexico, Venezuela !, Peru]. 



CXIX. BORAGINE.E. 



Stamens usually 5, inserted into the sympetalous, mostly imbricative corolla. Ovary 

 superior, 2-carpellary, 4-celled : ovules single in each cell, pendulous. Seeds exalbuminoiis, 

 rarely furnished with thin albumen. — Leaves mostly alternate, exstipulaie, often rough ; 

 flowers usually gyrate, ebracteate. 



This Order is mucilaginous, and yields emollient drugs, e. g. Cordia globosa. The drupes 

 of Beureria, Ehretia, and some Cordite, e. g. C. alba, are eatable. Several Cordite, e. g. C. 

 gerasca?dhus, C. gerascanthoides (Spanish elm, or prince-wood) are reputed timber-trees. 



1. CORDIA, L. 



Calyx tubular, often closed in the bud. Corolla infundibular or salver-shaped. Style 

 twice bifid. Drupe 4-1 -celled. Cotyledons corrugate. — Woody plants ; flowers in ex- 

 panded or contracted cymes, sometimes polygamous.
