180 BORRAGINACE^. Cordia. 



nicate scales. Stamens and style included: stigma 2-lobed. Nutlets ovoid, oblique, 

 coriaceous, coarsely reticulate-rugose, erect, almost laterally attached to a thickened 

 protuberant gynobase ; the scar large, oval, excavated or perforate, bordered by a 

 thickened cartilaginous ring. 

 2 1 . ECHIUM. Corolla f unnelform, with dilated throat oblique and not at all appendaged ; 

 * the lobes unequal, roundish, erect or slightly spreading. Stamens unequal and exserted : 

 filaments filiform. Style long and filiform, 2-cleft at apex : stigmas small. Nutlets car- 

 tilaginous, rough or rugose, ovoid, acute, erect, fixed to the flat gynobase by a plane and 

 marginless scar. 

 BorrAgo officinalis, L. (Borage), with very rotate blue corolla, is a not uncommon 

 annual in country gardens, but does npt run wild. Omphalodes linifolia, Moench, of 

 S. Europe, is given in Hooker's Flora Boreali-Americana, on the strength of a specimen re- 

 ceived from Newfoundland, to which it cannot be native, and the plant is rare in gardens, 

 in which 0. vekna is a hardy perennial, but it does not escape.

century.) — Tropical or subtropical trees or shrubs, the greater portion American.

§ 1. Corolla large, an inch or two long, f unnelform, deciduous ; the tube longer 



than the cylindraceous calyx; its lobes and the stamens 5 to 12: drupe enclosed 



in the enlarged calyx: inflorescence open-cymose. — § Sebestenoides, DC. 



C. Sebestena, L. Tall shrub or small tree, scabrous-pubescent or smoothish : leaves 

 ovate (4 to 8 inches long): flowers pedicelled : calyx not striate; the teeth irregular and 

 obtuse : corolla varying from orange to flame-color, 5-8-lobed. — Bot. Rep. t, 167. C. speciosa, 

 Willd., DC. — Keys of Florida. ( W. Indies, &d.) 



C. Boissieri, A.DC. Soft-tomentose : leaves oval or oblong-ovate, when old minutely 

 rugose and somewhat scabrous above : calyx not pedicelled, somewhat campanulate and 

 striate; the teeth often acute: corolla white with a yellow centre, 5-lobed, externally 

 downy. — DC. Prodr. xi. 478; Torr. Bot. Mex. Bound. 135. — Southern frontier of Texas 

 and New Mexico, Berlandier, Gregg, Schott, &c. (Mex.) 

 § 2. Corolla small or proportionally large, salverform or funnelform, deciduous : 



calyx short, not sulcate-striate ; its lobes and those of the corolla as well as stamens 



no more than 5, sometimes 4 : flowers in our species capitate-glomerate, and the 



leaves serrate ! — § Myxa, Endl. 



C. globosa, HBK. Shrub hirsute or somewhat hoary : branches slender, spreading : 

 leaves oblong-ovate, obtusely serrate (an inch or two long), the pinnate veins rather con- 

 spicuous and the upper surface often rugose : peduncle mostly short : calyx-teeth nearly 

 filiform, longer than the tube: corolla funnelform, white (2 to 4 lines long), about twice 

 the length of the calyx. —Nov. Gen. & Spec. iii. 76. Varronia globosa, L.,& V. hullata in 

 part. Cordia hullata, DC. Prodr. ix. 496 ; Chapm. Fl. 329. — Keys of Florida, Blodgett, &c. 

 (W. Ind. to Isthmus.) 



C. podocephala, Torr. A foot or two high, woody only at base, minutely strigose- 

 hirsute, scabrous : branches slender, erect : leaves varying from ovate-lanceolate to linear- 

 lanceolate, narrowed at the base into a short petiole, coarsely serrate (an inch or two 

 long) : peduncles filiform, 2 to 4 inches long, bearing a small and very dense head : calyx- 

 teeth triangular-subulate or ovate, very much shorter than the tube ; corolla broadly fun- 

 nelform, white or pale purple (half inch or more long), its narrow tube hardly exceeding 

 the calyx. — Bot. Mex. Bound. 135. — Lower Rio Grande, Texas to the borders of New 

 Mexico, Wright, Bigelow, Schott, &c. (Adjacent Mex.) 

 C. Greggii, Torr. 1. c, which is hardly of this section, is a Mexican species, found only at 



a considerable distance from our frontiers.

 apothecary, not Beurrer, therefore the orthography Beurreria, Jacquin and others, 

 is not to prevail over the original form.) — Tropical American trees and shrubs ;
