8 PLANTEZ FENDLERIANE.

28. CaRDAMINE CORDIFOLIA (sp. nov.): caule erecto simplici e rhizomate fibrilloso 
repente basi piloso usque ad apicem folioso; foliis omnibus petiolatis cordatis parce 
repando-dentatis angulatisve ciliatis, infimis rotundatis, superioribus triangulato-cordatis 
subacuminatis ; floribus majusculis albis ; siliquis immaturis erectis pedicello duplo longi- 
oribus. — Margin of Santa Fé Creek, in the mountains ; May, June. — A species nearly 
allied to C. rhomboidea, C. rotundifolia, and C. asarifolia ; distinguished from the first 
by having numerous cauline leaves which are all cordate and petioled, and by its shorter 
fructiferous pedicels ; and from the second by the stouter stems, the cordate, acute, and 
ciliate upper leaves, thickish pedicels, larger flowers, &c. It appears to be stoloniferous 
from the base. ‘The foliage is more like that of C. asarifolia; but the leaves are not 
reniform, or rounded except. the lowest, and are 14 to 23 inches long. 
29-31, Sisymprium icisum (Lngelm. Mss.): “annuum vel bienne ; caule glabri- 
usculo seu puberulo seu glanduloso-piloso ; foliis pinnatisectis, segmentis lanceolatis vel 
lineari-lanceolatis inciso-serratis ; petalis flavis lanceolato-spathulatis calycem superanti- 
bus; pedicellis calyce ter-quaterve longioribus, fructiferis (racemo fructifero elongato) 
patentibus capillaribus siliquas lineari-filiformes erecto-patentes subeequantibus ; valvis in- 
distincte uninerviis.” — Banks of streams in New Mexico; Santa Fé Creek and Mora 
River; June to August. Plant 1 to 2 feet high, branching, at length almost glabrous. 
Silique about 5 lines long; the valves with one indistinct middle nerve. Seeds linear- 
oblong, yellow, almost smooth, in one row. — Distinguished from S. Sophia by the 
longer petals, shorter silique on proportionally longer pedicels, and coarser, much less 
divided leayes. No. 29 and No. 31 are forms with large leaves, their lanceolate seg- 
ments coarsely serrate or incised. No. 30 is a very imperfect and dubious specimen. - 
— From Clear Water, Oregon, by Mr. Spalding, I have another form (f. FILIPES) of 
the same species, with the divisions of the cauline leaves narrowly linear, sparingly 
incised or incisely pinnatifid, or some of them quite entire, and with fructiferous pedicels 
three fourths of an inch long and longer than the pods. The species would appear to 
stand between S. Sophia and S. tanacetifolium, L. (Hugueninia, heap? with 
which, like its allies, it accords in the barely one-nerved valves of the silique. 
32. S. canescens, Nutt. Gen. 2. p. 68. Dry hills around Santa Fé. Valves of 
the silique only one-nerved, as in Hugueninia ; but the seeds more or less 2-seriate. 
high, mostly simple. . Leaves from 3 to 7 inches long, and with petioles of about half their length ; the lower 
with a hastate-lanceolate or triangular outline ; the upper broadly lanceolate with a truncate, rounded, or often 
a tapering base. Flowers two or three lines long. Petals narrowly spatulate, gradually narrowed into a 
canaliculate barely concave claw.  Siliques numerous, in a virgate raceme, three inches long, two lines wide : 
valves membranaceous ; the midnerve distinct at the base, but evanescent below the middle. Septum 
nerveless; the areole oblong, bounded by even lines.
