﻿8 PLANTJE FENDLERIANiE. 



^ 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 rotuudatis, superioribus triangulato-cordatis 

 subacuminatis ; floribus majusculis albis ; siliquis immaturis erectis pedicello duplo longi- 

 oribus. — Margin of Santa Fe 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 1J to 1h inches long. 

 •^29-31. Sisymbrium incisum (Engelm. 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 Iongioribus, fructiferis (racemo fructifero elongato) 

 patentibus capillaribus siliquas lincari-filiformes erecto-patentes subsequantibus ; valvis in- 

 distincte uninerviis." — Banks of streams in New Mexico ; Santa Fe Creek and Mora 

 River ; June to August. Plant 1 to 2 feet high, blanching, 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 leaves. 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 (/3. 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, Reichcnbach), 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 Fe. 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 areolae oblong, bounded by even lines.
