182 BORRAGINACE^. Coldenia. 



C. Gveggii, Gray. Suffruticulose, a foot or two high, tomentose-canescent : leaves ovate 



or oval (2 to 4 lines long], short-jjetioled, almost veinless, entire, the margins revolute : 

 flowers capitate-glomerate at the summit of the branches : calyx-lobes iiliform from a 

 broader base, elongated-plumose with long villous hairs : ovary obscurely 4-lobed ; but the 

 fruit even, ovate-oblong, by abortion 1-celled and 1-seeded, the walls comparatively thin, 

 showing mere vestiges of tliree abortive cells : embryo straight. — Ptilocali/x Greggii, Torr. 

 1. c. 170, t. 8. — Rocky ravines, New Mexico, and south-western borders of Texas, Gregg, 

 Wright, &c. (Adjacent Mex.) 



§ 2. Eddya, Gray. Fruit deeply 4-lobed ; the mature nutlets rounded and 

 only ventrally united, thiu-walled but crustaceous, rough-granulate: corolla not 

 appendaged : stamens unequally inserted : narrow leaves with very thick midrib, 

 veinless. — Eddya, Torr. 1. c. 



C. hispidissima, Gray, 1- c. Suffruticulose, diffuse, soon procinnbent, a span or two 

 high, very setose-hispid, and with some minute cinereous pubescence : leaves fascicled, 

 rigid, lanceolate, soon linear or acerose by strong revolution of the margins, dilated at 

 base ; the lower or primary ones petioled : flowers scattered : calyx-lobes linear, resembling 

 the leaves: embrj'o straight. — Eddga hispidissima, Torr. I.e. 170, t. 9. — Dry hills, &c., 

 W. Texas ( Wright, &c.) to Arizona and S. Utah. 



§ 3. TiQuiLiA, DC. Fruit deeply 4-lobed (or by abortion occasionally fewer) ; 

 the thin-walled nutlets rounded and united only at the centre, smooth and shining : 

 stamens equally inserted : leaves entire, petioled, veined. — Tiquilia, Pers. Gala- 

 pagoa, Hook. f. — In our species (§ Tiqiiiliopsis, Gray, 1. c), the corolla is appen- 

 daged within, and the cotyledons either 4-parted around or incumbent upon the 

 radicle. 



C. Nuttallii, Hook. Prostrate annual, repeatedly and divergently dlchntomous, cancs- 

 cently pubescent, also sparsely hirsute or hispid : leaves ovate or rhomboid-rotund, 2 to 4 

 lines long and on longer petioles, with two or at most three pairs of strong and somewhat 

 curving veins, and margins somewhat revolute : flowers densely clustered in the forks and 

 at the ends of the naked branches : calyx-lobes linear, sparsely hispid, equalling the tube 

 of the pink or whitish corolla : filaments shorter than the anthers, inserted nearly in the 

 throat of the corolla, the tube of which bears 5 .short obtuse scales near the base : nutlets 

 oblong-ovate, marked with a linear and rhaphe-like ventral scar : embryo straight : cotyle- 

 dons very deeply horseshoe-form, their elongated bases almost enclosing the radicle. — Kew 

 Jour. Bot. iii. 296; Watson, Bot. King, 248 ; Gray, Bot. Calif, i. 520. Tiqidlia brevifoUa, 

 Nutt. ; Torr. Bot. Mex. Bound. 130, & Wilkes Exped. xvii. 417, t. 12, under the name of 

 T. Oregana. — Arii}i plains, Arizona through Utah and E. California to Wyoming and 

 Washington Terr. 

 C Palmeri, Gray. Apparently perennial or even suffruticulose at base, less prostrate, 

 more canescent but not hispid or even hirsute : leaves obovate or ovate, about the length 

 of their petiole, plicatc-linc ate by about 6 pairs of straight and strong veins : flowers fewer 

 in the clusters ; calyx less deeply cleft ; the lanceolate lobes about half the length of the 

 bluish corolla, which bears 5 salient plates above the base of the tube, extending to the 

 insertion of the slender filaments : nutlets only one or two maturing, globular, with an 

 orbicular scar : cotyledons very tiiick, somewhat hemispherical, not even cordate, incum- 

 bent on the radicle. — Proc. Am. Acad. vii. 292, & x. 49; Watson, 1. c. Tiqiulia hrcvifolia, 

 var. plicata, Torr. Bot. Mex. Bound. 130. — Sandhills on the Mohave and Colorado, 

 E. California and W. Arizona, Emon/, Schott, Cooper, Palmer. 



5. TOURNEFORTIA, L. {Joseph Pitton de Toumefort, of France, the 

 great botanist of the 17th century.) — Shrubby, arborescent, or rarely nearly 

 herbaceous plants ; a rather large genus all round the world in and near the 

 tropics, one or two extratropical. Flowers white, small, unilateral and as it were 

 spicate on the scorpioid cyme-branches, usually destitute of bracts. A polymor- 

 phous and artificial genus, in a few species too nearly approaching the next.
