which it seems to be but a small form. Posé creek; August. 
MIMULUS EXILIS, nova species. —Herba circa pedalis erecta gracillima, ad apicem vix paulum 
ramosa, exsucca, sparse villosa. Caulis teres, jam prope basim et abinde flores singulos vel 
oppositos pedunculis setiformibus foliaque superantibus prodens. impiam 1-14” longa. 
Folia opposita sessilia elliptico-lanceolata, 2" longa. Calyx inflato t b latus (?) 
oblique quinquefidus, segmentis acutis, inferioribus majoribus latioribuan tn, demi magis 
inflatus. Corolla 4" longa, flava, limbo parvo, fauce pilosa maculata. Stamina inclusa. Cap- 
sula membranacea ovato-lanceolata subacuminata, calycem demum equans. Semina parva 
ovata, testa granulata. Herba habitu a reliquo genere Mimulo satis diversa. Forsan subgenus 
vel genus novum (Cerastodium?) instituendum. 
. A slender erect herb, sparsely villous, a foot or more high, not succulent. Stem terete, fili- 
form, a little branched near the top. Internodes one to nearly two inches long. Leaves sessile, 
elliptico-lanceolate. Peduncles setiform, longer than theleaves. Calyx oblique, subangular (?) 
deeply fivecleft, at first campanulate, and finally inflated. Corolla 4" long, yellow, limb 
small, fauces pilose, spotted. Stamens included. Capsules membranaceous, ovate-lanceolate 
pointed, finally equalling the calyx, #’ long; seeds small, ovate, testa granulate. Habitus 
rather different from that of the genus Mimulus. Posé creek, August. 
CASTILLEJA CANDENS, nova species.—Herba circa pedalis erecta, nonnunquam ramosa, basi 
glabra, supra cinereo-pubescens, bracteis calycibusque omnino rubentibus, basibus obscuris, api- 
cibus fulgentibus ; corollis glaberrimis, maxime exsertis, pallide atroflavis cunctisque nigricante 
venosis. Folia circa pollicaria, inferiora integra, linearia, acuta; csetera profunde tripartita, 
trinervia, segmentis linearibus ; floralia latiora, apicibus acuminato-lacinulatis. Calyx 14-13”, 
subinflatus bifidus, lobis lanceolato-bidentatis. Corolla fere bipollicaris striata, labio superiori 
seepe pollicari, inferiori rudimentario. 
Herbaceous, erect, about a foot high, and, except towards the base, grayish puberulent ; 
less so on the lower surface of the leaves. Leaves 1” or more long, and, as well as 
their segments, linear, the lower ones entire, acute; all others tripartite, trinerved ; those 
of the inflorescence broader and acuminately adi Rate at their apex ; the upper, as well 
as the calyx, entirely red and darkly veined, dusky at the base, scarlet at the top. Calyx 14 to 
13" long, subinflated, bifid, each lobe lanceolately bidentate. Corolla 2" long, smooth, of light 
fuscous yellow, with black veins ; the lower lip ET, the upper often 1” long. In 
river bottoms, Pose creek ; August. y
