of the leaves in this are green. The flowers too are smaller in P. 
glaucum. It differs from A. nevadense Goodding in that the leaves 
of the latter are also green above. The finely twisted and pointed 
convolute ccrolla in bud is a striking character. 
A. calophyllum Greene has much larger leaves and inflores- 
cence. The flowers are larger and more densely crowded, and 
the corolla has broader lobes. The buds of A. calophyllum are 
not pointed, and the calyx not as deeply cleft. The leaves. too, 
are dark green on the upper surface. 
The type is in the U. S. National Herbarium, No. 322,005, 
and No. 1875 of the Geological Survey of California collected 
July 15, 1863 near Walker River. 
Tovara virginiana (Linn.) Raf., var. Kachina Nwd., nov. var. 
Planta tota praesertim ochreae, pedunculi, et folia hispido- 
hirsuta pilis fulvis: folia 5.5-17 cm. longa, 2—6.5 cm. lata, elliptica 
vel (excepto apice acuminato) perfecte ovalia; ochreae mem- 
branaceae pilis fulvis crassis cooperta, et majoribus rectis appressis 
ciliatae; bracteae inflorescentiae hirtellae et ciliatae: | Flores 
rosei, plus minusve conferti, inferiores 3-8 mm. distant ab allis 
et florescentes superiores perpropinqua: spicae 2.4—3.9 dm. longae: 
pedunculus 4.5-12 cm. longus: semina lentis formae, nigra 
vel fusca binis stylis apice praedita. 
Whole plant and especially the ochreae, peduncle and leaves 
particularly, and the lower surface of the latter rather densely 
hispid-hirsute with rough tawny appressed hairs: leaves 5.5-17 
‘em. long, 2-6.5 cm. broad, elliptic or (but for the acuminate 
apex) perfectly oval in shape. Ochreae membranous beset with 
long tawny rough hairs and their margin ciliate with longer straight 
ones. Stem,..peduncle,. and. rachis also hirsute: flower .bracts - 
ciliate and .their surface hirtellous: flowers. rose colored. rather 
closely aggregated on the rachis, the lower 3-8 mm. apart and when 
beginning to flower almost contiguous; spikes 2.4-3.9 dm. long: 
peduncle 4.5-12 cm. long: seeds lenticular in shape, black or brown 
with the two persistent hooked styles at the apex. 
The plant differs from T. virginiana (Linn.) Raf. in the re- 
markably coarse pubescence of the whole plant, the shape of 
the leaves, and the closer aggregation of the flowers. Our American 
plant is seldom more than minutely strigose, and has ovate leaves. 
The flowers are smaller and the whole inflorescence much longer
