Enumeration of Plants of the Rocky Mountains. [257] 31 
with white folds.”—* Many leafy, oné-flowered, erect or ascending branches, 
2-5 inches high, from the base. Distinguished from the allied species, 
and especially from G. prostrata, by its larger rosulate lower leaves, 
which, as well as the oblong-linear cauline leaves, are cuspidate and often 
on the lower ones I find them often enclosed, or bursting sideways through 
the integuments. Siberian specimens are absolutely identical with the 
Rocky Mountain plant.” Hngelm 
307. Gentiana acuta, var. stricta, Griseb, “Rather common in shady 
pine woods and moist places 0 on Upper Clear Creek. In shaded places 
the leaves are pale-green on both surfaces, broad and mostly obtuse; the 
flowers very pale-blue; in more open localities the leaves are dark- green 
above, pale below, narrower, the upper most acute, the flowers darker.” 
“Stems a foot high, leaves 1-1 inches long, 3-7 lines (the lower ones) 
wide. Flowers about 4 inch long, always 5- ease lobes of calyx bi 
is Sitinguished by ess acute leaves, and especially by the larger ca- 
lyx. As specimen from . er Canada in Herb. A. Gray, probably, repre- 
m 
regut lar ar? bey calyx, and very acute lobes of the corolla. The very 
nearly allied G. Amarella of northern Europe has the corolla much less 
deeply divided with cr obtuse lobes.” Hngelm. 
var. 
nana, Engelm. in Transact. St. Louis Acad., 
2, t. 9, fig. 6-9. “In ae higher alpine se se together with G. pros- 
trata, in masses of Silene acaulis.” “A diminutive form, 14-2 inches 
high; flowers _ smaller; lobes of 4-5- te corolla obtuse; beard 
consisting of few distinct fibres.” Engelm. This, from the obtuse lobes 
of the corolla, would appear to confirm Dr. Hooker's view that @. acuta 
is a form of G, Amarella, represented in Lapland by @. lingulata, Ag: 
e ee aks distributed with No. 309 are i: ordinary G. acuta iD 
can specimens (No. 686) have large and obtuse leaves (12-16 
inches long, 4-5 inches wide); even the cauline es are broadly oval, 
only the uppermost being lance-linear; the inflorescence is loose, an the 
flowers much larger. Dr. Parry’s plant resembles more the figure in 
Hooker’s flora. The cup uniting the base of the stamens is ciliate on its 
‘in = species. Frasera inensis has large, obovate-spatulate, 
rolle rubre adeequante ; corolle lobis rotundatis obcordato-bifidis.—Limb 
of the corolla an inch in diame i ine 
long. This magnificent Prowse needs to be compared with Ledebour’s 
Am, Jour. Sci.—Szconp Szgres, Vou. XXXIV, No. 101.—Sepr., 1862.
