NEW OR NOTEWORTHY SPECIES. 87 
Collected by the writer at the summit of Mt. Diablo, Calif., 
20 June, 1892, and very erroneously referred, at the time, 
to T. lacinatus; from which it is distinguished not so defi- 
nitely by its pubesence as by the remarkable character of 
the pods. In the structure of the wing of the fruit this 
species is equally removed from the group of the original 
species and from T. radians; but it has an ally in T. Palmer? 
of the far-distant Cedros Island. 
THYSANOCARPUS AMPLECTENS. Stem stoutish, simple and 
leafy below, with a few racemose branches at the middle, 12 
to 20 inches high, glabrous throughout and very glaucous : 
lowest leaves unknown ; cauline linear-lanceolate, remotely 
and retrorsely dentate, with very conspicuous sagittate lobes 
at base which clasp the stem : white petals shorter than the 
purple (white-margined) sepals; stamens scarcely exserted : 
pod nearly orbicular, glabrous, the body reticulate-venulose, 
the wing of 14 to 16 short rays and a regularly crenate hya- 
line margin, but no perforations. 
Type collected by the writer in southwestern New Mexico, 
16 April, 1880; referred by Asa Gray at the time to T. ele- 
gans, from which species its perfectly glabrous and strongly 
glaucous herbage effectually excludes it. It is really of the 
group to which T. lacinatus belongs, though its very con- 
spicuously sagittate-clasping and merely dentate leaves, as 
well as its mode of growth, prevent its being confused with 
that species. I do not know how much of the Thysanocar- 
pus materials from Arizona now extant in herbaria may be 
referable to this very distinct extra-Californian member of 
e genus. i 
^ Viora Lawerorsu. Acaulescent and low, the subterra- 
nean caudex usually simple and erect: leaves of rather firm 
texture and somewhat conspicuously veiny, from reniform- 
cordate (in the earliest) to somewhat hastately deltoid, del- 
toid-ovate and ovate-cordate (in the later and larger), acute
