NYCTAGINACE.E. 33 



and the herbaceous ones, glabrous and very glaucous: leaves 

 much smaller than in A.frograns, subcordate-orbicular to 

 oval, very obtuse, usually about an inch long, on petioles 

 somewhat longer or shorter: flower smaller than in A. fra- 

 grans, the perianth-limb apparently funnelfrom rather than 

 rotate: fruits scabrous on the sides, roughish-tomentulose at 

 summit. 



This species, easily distinguished from the northern and 

 and true A. fragrans (a large perennial, wholty herbaceous) 

 by its small size, suffrutescent habit, white stems and total 

 lack of clamminess, is well represented in the following 

 numbers: 13, obtained at Montrose, best showing the half- 

 shrubby growth ; 89, from Deer Run, somewhat larger, and 

 92, from Grand Junction; this last, at least in my set, is a 

 young plant, flowering perhaps the first year from the seed, 

 and thus exhibiting, naturally, no sign of the ultimate 

 woodiness of the stem. 



ALLIONTA ROTUNDIFOLIA. About a foot high, the stoutish 

 clustered stems ascending, densely crinite-hirsute as to the 

 lower and shorter internodes, the upper portions, as well as 

 the lower face of the uppermost leaves more loosely and 

 hispidly hirsute: lowest leaves suborbicular, obtuse, about 

 1 J inches long, the upper larger, sometimes round-ovate, all 

 more or less woolly-ciliolate: flowers and fruits not seen. 



Obtained at Swallow's, between Pueblo and Canon City, 

 1 June, n. 3. The specimens, though not yet in flower, 

 exhibit in their peculiar foliage and pubescence characters 

 sufficient for the establishment of a species. The inflores- 

 cences are clustered, and arise from the axils of only the 

 uppermost leaves.

THERMOPSIS PINETORUM. Less than a foct high at flower-
