Mimulus Scouleri, Hook. FI. Bor. Am,., vol. II, p. 100. Might be referred to M. luteus, of 
which it seems to be but a small form. Pose 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. Internodia 1-1^" longa. 
Folia opposita sessilia elliptico-lanceolata, §" longa. Calyx inflato-campanulatus subangulatus (?) 
obliqtfe quinquefidus, segmentis acutis, inferioribus majoribus latioribusque, demum magis 
inflatus. Corolla 4'" longa, flava, limbo parvo, fauce pilosa maculata. Stamina inclusa. Cap- 
sula membranacea ovato-lanceolata subacuminata, calycem demum sequans. Semina parva 
ovata, testa granulata. Herba habitu a reliquo gen ere 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 the leaves. Calyx oblique, subangular (?) 
deeply fivecleft, at first campanulate, and finally inflated. Corolla 4 W 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. Pose 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 ; cietera profunde tripartita, 
trinervia, segmentis linearibus ; floralia latiora, apicibus acuminato-lacinulatis. Calyx 
subinflatus bifidus, lobis lanceolato-bidentatis. Corolla fere bipollicaris striata, labio superiori 
ssepe 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 lacinulate at their apex; the upper, as well 
as the calyx, entirely red and darkly veined, dusky at the base, scarlet at the top. Calyx 1£- to 
long, subinflated, bifid, each lobe lanceolately bidentate. Corolla 2" long, smooth, of light 
fuscous yellow, with black veins ; the lower lip rudimentary, the upper often 1" long. In 
river bottoms, Pose creek ; August.
