BORRAGINACEiE. 411 



Hab. On the Walla-Walla River, Washington Territory. — Stem 

 2 to 6 inches long, much branched, usually prostrate. Leaves ovate, 

 clustered at the forks of the stem, 3 or 4 lines long, hairy, and at 

 length hispid, the nerves somewhat depressed on the upper surface : 

 petioles 1 or 2 lines long. Flowers in small axillary dense clusters. 

 Sepals narrowly lanceolate, hispid, with a few stouter spinose hairs 

 at the tip. Corolla twice as long as the calyx ; the lobes obtuse and 

 somewhat spreading. Stamens inserted about the middle of the tube. 

 Ovary subglobose, 4-lobed. Style filiform, 2-parted below the middle. 

 Nutlets ovate-oblong, gray, homomorphous, and all fertile, obtusely 

 angular and grooved on the face where they adhere to the base of the 

 style. xilbumen none. Cotyledons deeply 2-lobed from the base 

 nearly to the apex, the radicle originating below the cleft, surrounded 

 by the four lobules, and protruding beyond them. The cotyledons 

 may, perhaps, be regarded as excessively auriculate at the base. 



The genus Tiquilia was established by Persoon on the Lithospermum 

 dichotomum of E-uiz & Pavon, and was doubtfully regarded as a section 

 of Goldenia by De Candolle. The latter genus differs in its nearly 

 solitary flowers, nutlets connate in pairs, very short style, which is 

 2-parted at the base, and undivided cotyledons. It is more nearly 

 related, however, to Galapagoa, Hook, f., and has much the aspect 

 of G. fusca, which is also an annual, like Tiquilia, although called 

 perennial by Dr. Hooker. Galapagoa differs chiefly in the stamens 

 being inserted at the base of the corolla, the style 2-parted at the 

 base, and the undivided cotyledons. 



[In the fifth volume of the Proceedings of the American Academy 

 of Arts and Sciences, p. 341 (1862), this plant is characterized by the 

 present writer under the name of Coldenia (Tiquiliopsis) Nuttallii, 

 Hook.]
