V. DESCRIPTIONS IN ENGELMANN’S BOTANY OF THE UPPER MISSOURI. 
From HaypEn’s Report oN GEOLOGY AND NATURAL HIstToRY, IN THE TRANSACTIONS OF THE AMERICAN PHILOSOPHICAL 
OCIETY, N. s., VoL. XII. 1861, pp. 182-209.* 
NasTuRTIUM CALYCINUM,t Engelm., n. sp.: annuum erectum seu diffusum, hirsutulum ; foliis cau- [184, 730] 
linis anguste oblongis sinuatis seu subpinnatifidis basi auriculata arcte sessilibus vel semi amplexicaulibus ; 
racemosis confertifloris demum elongatis ; pedicellis flore flavido et silicula ovoidea acuta parva hispidula cum stylo gracili 
vix longioribus ; calyce persistente. In aspect as well as in the style (fully a line long on a silicle 14 line in length), 
this species resembles some Vescicarie, but the numerous seeds are those of a Nasturtium. The stem is about a foot 
high, often much branched and diffuse. The ovate-lanceolate acutish sepals commonly persist until the valves of the 
pod have fallen. The pubescence of the pod consists of very short and pointed thick-based simple hairs (A. Gray). 
Sandy bottoms of the Yellowstone River; Fort Sarpy to Fort Union. 
MACH&RANTHERA VISCOSA (Dieteria viscosa, Nutt.). [195] 
LITHOSPERMUM BREVIFLORUM, var. PUNCTULOSUM, Engelm.: hispidum, caulibus e radice perpendiculari [203] 
pluribus, erectis foliis linearibus; floribus eres osteaatr minutis; nucibus minoribus a exsculpto 
punctulosis. Sandy bottoms about Fort Union at the mouth of the Yellowstone River. The flowers are absolutely 
identical with those of the last [L. b7 iiitiviint otherwise the much greater roughness iss the aay sea nuts 
would seem to indicate specific difference.

VII. NOTE ON POLYGONUM TENUE.

PotrconuM TENvE, Miche. a. commUNE: majus; nucibus majoribus (sesquilineam longis). §. microsPER- [75] 
Mum : minus, gracilius ; nucibus vix lineam longis. y. Latirotrum : humile; foliis oblongis; spicis coarctatis ; 
bracteis superioribus (aristo destitutis) muticis. Meisner, in the Prodromus, is wrong in saying that the nuts are 
sub-opaque or rough on the edge ; they are perfectly smooth and shining, with concave sides and an acumination. — 
(Mar. 1863, as a note to a paper by Asa Gray on plants collected in the Rocky Mountains by Hall & Harbour.]
