180 BORRAGINACE.E. 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. 



21. ECHIUM. Corolla funnelform, 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 fiat 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 not run wild. (JMTIIALODES LIXIFOLIA, 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 O. VERNA is a hardy perennial, but it does not escape.

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

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

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

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

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

 downy. DC. Prodr. ix. 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 ! Myx, Endl. 



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

 leaves oblong-oyate, 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. bullata in 

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

C. podocepliala, 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, Biyelow, 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.
