Harpagonella. BORRAGINACE^E. 531 



Woods, from Monterey to Washington Territory. An unusually smooth form from Plumas 

 Co., Mrs. Pulsifer Ames. Nutlets not seen ; the moderately enlarging lobes of the ovary only 

 sparsely and minutely muricate on the back. 



2. C. OCCidentale, Gray. About a foot high, leafy to the top or nearly, rough- 

 ish-hirsute : leaves oblong or lanceolate, mostly obtuse and with a small point ; 

 radical and lower ones oblong-spatulate and tapering gradually into a long narrow 

 base or winged petiole ; the upper closely sessile and half-clasping : peduncle 2 or 3 

 inches long, bearing a small mostly forked cyme : corolla purple or violet, its tube 

 twice or thrice the length of the short and roundish lobes : nutlets horizontal at 

 maturity, very convex and tumid as in the Eastern C. Virginicum. Proc. Am. 

 Acad. x. 58. 



Sierra Co. and northward, Lemmon (in fruit), Rev. R. Burgess (in flower). 



10. PECTOCARYA, DC. 



Calyx 5-parted, persistent, spreading. Corolla very small, salverform or funnel- 

 form, with crests in the throat. Stamens and very short style included. Nutlets 

 widely spreading in pairs, horizontal, oblong or almost linear, surrounded by a more 

 or less incurved wing-like border, which is sometimes deeply cut into stout bristle- 

 bearing teeth, or is more or less beset with stiff bristles or slender prickles, the tips 

 of which are simply hooked. Gynobase very short. Radicle of the embryo centrip- 

 etal, i. e. pointing to the gynobase. Low and insignificant slender annuals, dif- 

 fusely branching; with hoary strigose-hirsute pubescence, narrow linear leaves 

 (barely half a line wide), and very small lateral flowers scattered along the branches, 

 on very short peduncles: corolla white. DC. Prodr. x. 120; Gray, Proc. Am, 

 Acad. x. 61. 



A genus of probably only two variable species, and perhaps of only one, inhabiting the western 

 coast of America from Chili to California, perhaps diffused since the introduction of sheep and 

 cattle, the nutlets being bur-like. 



1. P. lateriflora, DC. Nutlets about 2 lines long, surrounded by a rather 

 broad and thick expanded wing, which is deeply cut or parted into about 9 to 15 

 triangular-subulate teeth, more or less tipped with hook-bristly points. Cynoglos- 

 sum lateriflorum, Lam. C. pilosum, Ruiz & Pav. Pectocarya lateriflora, linearis, & 

 (a slender form) Chilensis, DC. 1. c. P. Chilensis, var. California, Torr. in Pacif. 

 R. Rep. iv. 124, where the character in the Prodromus as to the position of the 

 radicle is corrected. 



Dry sandy or gravelly soil, Los Angeles to Arizona and Southern Utah (Parry, Bigelow, &c.). 

 Also coast of Peru and Chili. 



2. P. penicillata, A. DC. Plants very slender : nutlets little over a line long, 

 with narrow and entire or rarely few-toothed wing, the apex thickly beset with 

 hooked bristles, the sides more or less incurved and naked or sometimes bearing a 

 few scattered bristles. Cynoglossum penicillatum, Hook. & Am. 



Common in sandy or gravelly soil along and near the coast. Also in N. W. Nevada, between 

 Long Lake and Soda Lake Valleys, Lemmon. Probably passes into the preceding. 



11. HARPAGONELLA, Gray. 



Calyx irregular ; three of the sepals distinct nearly to the base, two united to 

 near the middle. Corolla almost rotate, hardly surpassing the calyx ; the throat 

 with obtuse crests ; the roundish lobes imbricated in the bud. Style short : stigma 

 somewhat capitate. Divisions of the ovary globular, attached by the base to a 

 nearly flat receptacle, two of them apparently always abortive. Ovule nearly erect,
