SOME WESTERN POLEMONIACEA. 303 
Nevada; very distinct from the far northern species by its 
larger wholly red corolla with emarginate, or somewhat 
obcordate lobes. 
..6. M. uicRANTHA. Collomia micrantha, Kell. Proc. Calif. 
Acad. iii. 18 (1863). Dwarf, usually only 2 or 3 inches high 
and with but 2 or 3 pairs of properly cauline leaves, these 
from round-ovate to oblong, obtuse, hispid-ciliolate on the 
margin, and with similar hairs scattered over the surface of 
the leaves and clothing the stem, this and the inflorescence 
bearing also the usual finer gland-tipped hairs: inflorescence 
compact (the plant in fruit as broad as high): flowers all 
geminate, and the pedicels not very unequal: calyx-teeth 
pungently acute, searcely half the length of the tube: tlie 
minute corolla well exserted, the limb pale purplish, the tube 
white: capsule elongated-oval. 
Of the desert regions of eastern California and western 
Nevada, extending southward to northern Arizona; perhaps 
also including the still more dwarf white-flowered plant of 
Wyoming, Colorado and New Mexico; though this, for 
geographical reasons may be expected to prove distinct. 
7. M. ANDICOLA. Collomia gracilis, var. andicola, Benth. 
in DC. Prodr. ix. 308. Described as perfectly glabrous 
throughout, and with subspathulate calyx-segments; by 
which characters alone one must accept it as altogether dis- 
tinct from all the North American species. It is attributed 
to the Andes of Chile, and Cuming’s n. 157 and Bridges’ n. 
587 are cited by Bentham as types. 
GYMNOSTERIS. 
Diminutive annuals devoid of proper foliage, the base of 
the stem showing even in maturity a turbinate or campan- 
. ulate sheath composed of the united and persistent cotyle- 
E dons; the capitate-congested inflorescence subtended by an
