7 ALLOCARYA Greene Pitt, i, 13. 



Low, mostly annual, herbs with entire leaves, the lowest al- 

 ways opposite, and rather small flowers in scorpioid racemes. 

 Calyx 5-parted to the base ; the segments spreading and some- 

 what enlarging in fruit. Corolla salverform, with a short tube, 

 yellow throat and white limb. Pedicels turbinate thickened and 

 more or less distinctly 5-angled under the calyx, persistent, more 

 or less indurated in age. Nutlets ovate to lanceolate, crustaceous, 

 opaque or vitreous-shining, smooth or variously tuberculate and 

 rugose-muriculate, or even glochidiate, often carinate on one or 

 both sides, attached by an inframedial or basal concave but 

 sometimes raised and stipitate scar to a low gynobase. 



* Small flowered annuals, usually diffuse, with corolla only a line 

 or two broad and but little surpassing the calyx. 



A. echinOfflochin Greene Pitt, i, 15. Echinospermum Oreenei Chay : 

 Strigose-pubescont with whitish hairs : diffusely branched from the base, 

 the branches 4-10 inches long, depressed : leaves linear, the lower 1-2 

 inches long, obtuse : racemes simple or forked, rather loose, leafy or bract- 

 eate at base, and sometimes above: calyx-segments oblong -linear, obtuse, 

 open but not reflexed in fruit, silky-hirsute with fulvous-yellow hairs : 

 corolla about equalling the calyx, its dilated limb about 2 lines broad 

 nutlets shorter than the calyx, ovate-trigonous, obscurely carinate on the 

 back, acutely so ventrally down to the low ovate scar, minutely tuberculate, 

 scabrous throughout and with small terete barbed prickles interspersed. 

 In wet places, southwestern Oregon and adjacent California. 



A. plebia Greene 1. c. 16. Eritrichium Californicum var. plebium Gray. 

 Sparsely and minutely hirsute or glabrate : branches depressed, 6-10 inches 

 long: leaves lax, the larger 2 inches long, linear-oblong: flowers scattered: 

 pedicels shorter than the calyx : segments of the calyx enlarged and open 

 in fruit: nutlets ovate- trigonous, a line long, glabrous, coarsely rugose- 

 reticulated, sharply carinate ventijally down to the large ovate scar and 

 dorsally only along the narrowish apex. Aleutian Islands Alaska, it has 

 been reported from Humboldt Bay California. 



A. hispidnla Greene 1. c. 17. Canescent with short setose-hispid pu- 

 bescence : diffusely branched from the base, the branches more or less 

 ascending, 2-6 inches long: racemes single or geminate,'na)ced, or leafy- 

 bracted below : pedicels about a line long : segments of the calyx linear, 

 longer than the nutlets, very hispid, erect, not enlarged in fruit : nutlets 

 ovate, opaque, ^ of a line long, carinate on both sides, the back very 

 lightly so and beset with minute muriculations, the transverse rugula few 

 and not prominent: scar almost basal, ovate-oblong. In moist meadows, 

 Washington and Oregon to California. 



A. Cusickii Greene 1. c. 17. Pubescence appressed : diffusely branch- 

 ed from the base, the branches 4-8 inches long : racemes open and leafy- 

 hracted : nutlets vitreous-shining, ovate-oblong, carinate ventrally only, 

 the back with crowded depressed rugse and few tuberculations : scar almost 

 basal, narrowly linear and sharp-edged. Union Co. Oregon. 



A. bracteata. Appressed-hirsute with minute setose hairs : diffusely 

 branching from the base and depressed, the branches slender, 2-8 inches 

 long : leaves linear, an inch or less long : racemes sparsely flowered and
