 cence, more or less white-mealy throughout: leaves rhombic-ovate, sinuate 

 or dentate, obtuse or acute, 2-4 cm. long, greener above: petioles slender, 

 nearly equalling the blade; uppermost leaves lanceolate and entire: panicle 

 commonly 30 cm. long: spikes axillary or terminal, rather dense: fruiting 

 calyx 1 mm. broad, the sepals keeled and arched over the lenticular fruit: 

 seed black, minutely pitted. A common weed in waste or cultivated ground. 



C. botrys L- Stems branched from the base, the branches erect or spread- 

 ing, 30-50 cm. high, glandular-pubescent throughout: leaves oblong, 2-5 cm. 

 long, pinnately divided into 5-6 irregular toothed lobes; petioles short, or 

 the uppermost leaves sessile: flowers very small, in loose axillary racemes or 

 panicles, these forming strict narrow panicles 10-30 cm. long: sepals dry, 

 ovate, loosely enclosing the fruit. A weed in sandy soil along Snake River. 



C, capitatum Aschers. Glabrous throughout: stems erect or spreading, 

 somewhat branched, 10-80 cm. high: leaves triangular, coarsely and unevenly 

 dentate, 2-6 cm. long, on petioles of about the same length: flower clusters 

 globose, dense, in the axils of the reduced upper leaves: calyx fleshy in fruit 

 and bright red, the clusters resembling strawberries: seed black, subglobose. 

 Introduced about Pullman. 



96. MOXOLEPIS. 



Low annual branching herbs: leaves small, narrow, alternate, 

 entire, toothed or lobed: flowers perfect or polygamous, in small 

 axillary clusters: calyx of one persistent herbaceous sepal: stamen 

 1: utricle flat: endosperm mealy. 



M. chenopodioides Moq. Stems erect or decumbent at base, branched 

 below, 10-40 cm. tall, glabrous or very sparsely inealy throughout: leaves 

 lanceolate, attenuate at each end. acute or obtuse, commonly with a single 

 large tooth or lobe on each side near the middle, 1-3 cm. long, the upper 

 sessile or nearly so, the lowermost slender petioled: flowers clustered in the 

 axils of the leaves on the elongate erect simple branches: sepal oblanceolate 

 or spatulate, acutish. Roadsides, rare in our limits. 



97. CORISPERMUM. 



Annual herbs: leaves alternate, narrow, entire, 1 -nerved: flow- 

 ers perfect, bractless, small, green, solitary in the upper axils, 

 forming terminal narrow leafy spikes, with the upper leaves 

 shorter and broader than the lower: calyx of one solitary thin 

 broad sepal, or sepals rarely 2: stamens 1-3, rarely more and one 

 of them longer: utricle ellipsoid, mostly plano-convex: endosperm 

 fleshy. 



C. hyssopifolium L. Stems spreading, much branched, 30-60 cm. high, 

 somewhat pubescent when young: leaves linear or linear-lanceolate, cus- 

 pidate, glabrous, 2-3 cm. long, sessile: spikes dense, 2-4 cm. long: bracts
