colored, the whole plant fleshy and exceedingly succulent 

 (specimens curing slowly and saved with difficulty) : leaves from 

 broadly lanceolate to oblanceolate or even linear in outline, entire 

 or irregularly toothed (often hastately toothed and resembling 

 those of Moiwlepis chenopodiodes), 2-5^"^ l^^i^^g* c»^ petioles about 

 half as long, green on both sides and not noticeably mealy; 

 floriferous thoughout : flower clusters axillary, spicate, very 

 numerous; calyx membranous; the sepals usually 3, suborbic- 

 ular : pericarp thin, rather loosely covering the small dark brown 

 seed. 



It is at once distinguished from C.glaucum by its erect habit, size, succu- 

 lence, greenness, crowded inflorescence, and small seeds. Type no. 8i82ti, 

 Albany co., Wyoming, Sept. 5, 1900.

Chenopodium subglabrum (Wats.), n. sp. — C. leptophylliim siib- 



glabnim Wats. Proc. Am. Acad. 9 : 95, — The following characters 

 seem to indicate that this rather rare plant is not very closely 

 allied to C. leptophyllum Nutt. It is glabrous, usually bright 

 green ; loosely and slenderly branched, the branches very widely 

 divaricate; the few-flowered clusters scattered on the branches. 

 In this last respect especially it is as strongly marked as in its 

 habit. The flowers are often borne singly and never more than 

 two or three in a cluster. The fruit is large and depressed, and 

 the calyx loose and open at maturity. Of several specimens 

 examined in the herbarium of the Missouri Botanical Garden, 

 no. 274, by Mr. Waugh, Stillwater, Oklahoma, shows the fully 

 developed characters especially w^ell. The range of the species

leptophyllum seems much less well marked, 

 to say whether a given plant should bear the varietal or specific 

 designation. Under this varietal name, however, a form has 

 been found that by reason of its habit and other characters 

 seems to deserve specific rank.
