, PLANTH FENDLERIANZ. 9 
_ 33, Erysimum asperum, DC.; Hook. Fl. Bor.-Am. 1. p, 64. t. 22. In ripe fruit. 
— San Miguel to the east of Rock Creek, in patches of fertile and loose soil, on high 
prairies; August. — Cotyledons incumbent. Siliques spreading. 
34. E.asperum, DC. With rather small flowers and narrow leaves: yet scarcely 
agreeing in the length of the petals with E. parviflorum, Nutt. — Valley of Santa Fé 
Creek ; May to July. | 
35, E. asperum, DC., var. A less hoary form, with larger flowers; the young si- 
liques erect. — High on a ledge of rocks overlooking the Rio del Norte; May. — Mr. 
Nuttall has apparently multiplied the species unduly. 
736. Sranteya pinnatiriva, Nutt.! Gen. 2. p.71; Gray, Gen. Ill. t. 65.— A single 
specimen was gathered in September, 1846, fifteen miles northeast of Rio de los 
Animos, between Bent’s Fort and New Mexico. It bears nearly full-grown pods, as 
well as flowers, although all the lower part of the dense racemes have been unfruitful. 
The upper leaves are linear, and many of them, and even of the lower, are entire or 
nearly so. Hence it may be S. heterophylla, Nutt. ; but the lamina of the petals is 
much shorter than the claws. — Although not mentioned in Hooker’s Enumeration of 
Geyer’s collection, I possess a specimen, distributed as No. 97, of what appears to be 
S. viridiflora, Nutt. The thick and smooth leaves are all perfectly entire. 
737. Sinaris nigra, Linn. Near irrigating ditches, Santa Fé; June, July. Doubt- 
less introduced. 
38. -Vastexnira-anerva, Nutt. in Torr Grat, 1. 1. p. 102; Hook.! Lond. Jour. 
Bot. 6. p. 70. On the lesser hills west of Santa Fé, in pebbly and dry soil, on 
gently sloping declivities ; April to May, and, in fruit, June 7th. — Abundant and fine 
specimens of this rare species are distributed. The dense, silvery tufts are completely 
covered with the showy, golden-yellow blossoms. It would be a charming plant for 
rockwork. In some specimens the style is considerably shorter than the silicle. 
+39. V. arctica, Richards., var. a. Hook. Fl. Bor.-Am. 1. p. 48 ? Dry, gravelly 
hills, Santa Fé; May. In flower only. 
+40. V. Fenpueri (sp. nov.): suffruticosa, nana; caulibus ramosissimis dense foliosis 
paucifloris ; foliis spathulato-linearibus brevibus (4-4 unc. longis) integerrimis argenteo- 
incanis, infimis rosulatis ; siliculis globosis glaberrimis stylo tenuissimo paulo brevioribus. 
— On the smaller hills around Santa Fé; with No. 38. The single, but very perfect 
specimen, gathered on the 21 of May, is almost entirely in fruit. The numerous stems 
are two or three inches high, branched from the base, and the shoots of the year are 
thickly clothed with the silvery leaves, which are much smaller than in any other species. 
The flowers are apparently less than half the size of those of V. Ludoviciana, and only _
