120 BOTANY. 
longiori) angusto subito ventricosa campanulata modice bilabiata, lobis 5 consimilibus rotundatis 
pat ntibus; filamento sterili filiformi glabro; antheris (Cepocosmi) glabris. San Francisco 
Mountain, New Mexico, December 16. Imperfect specimens, with fruit only. But they clearly 
belong to a species which we first received from Mr. William A. Wallace, from Cocomungo and 
Los Angeles, California ; and soon after from Mr. George Thurber, who gathered it in the same 
district. Mr. A. B. Gray likewise gathered fragments of the same on the Gila river. It must 
be one of the showiest species known, and it will appropriately bear the name imposed upon it 
by Mr. Thurber. The crowded pianicle of purplish blue flowers is often two feet in length, and 
free from leaves, the lowest bracts not exceeding the peduncles, while the upper are reduced to 
small and inconspicuous perfoliate disks. Peduncles and spreading pedicels each half an inch 
to an inch long. Sepals 3 lines long, obtuse or apiculate. Corolla an inch or more in length ; 
the proper tube about twice the length of the calyx, then abruptly expanded into à campanulate 
. throat, glabrous inside; the two lips of equal length, and the lobes very similar. Leaves ap- 
parently somewhat glaucous, 3 or 4 inches long ; only the radical petioled ; all the upper 
cauline connate into a disk, which is an inch or two in width where it is perforated by the stem. 
DIPLACUS GLUTINOSUS, Nutt. Hill-sides, Sonoma, Punta de los Reyes, etc., California; May. 
The species also includes D. leptanthus and D. longiflorus of Nuttall.

Valley, etc., California, and Williams’ River ; February—May.

May. A small form. : 
MIMULUS INCONSPICUUS (sp. nov.): annuus, glaber; caule gracili 1-2-pollicari adscendente 
paucifoliato ; foliis ovalibus seu ovatis subintegerrimis obsolete 3-5-nerviis subsessilibus; pedun- 
culis solitariis foliis et flore parvo brevioribus ; calyce prismatico, dentibus brevissimis sube- 
qualibus; tubo corolle paullo exserto. Damp hill-sides, Los Angeles, California, May. 
Leaves 5 or 6 lines long, the cauline only a single pair in the specimens, Peduncle 2 or 3 lines 
long. Flower 4-5 lines long; the corolla yellow tinged with rose-color in the dried plant, its 
lobes very small. Fructiferous calyx not seen. 
Euxanus Dovarasm, Benth. in DC. Prodr. 10, p. 374. Gravelly hills, Sonora, and Moke- 
lumne Hill, California; May. The former specimens, like those of Douglas, etc., are very dwarf 
and simple ; the stem, of only 2 or 3 internodes above the cotyledons, barely half an inch long, 
while the flower it is terminated with is fully an inch long. Those from the latter locality, 
like Hartweg's No. 1894, are developed into many-flowered branches 4 inches high, the lower 
part fructiferous. To Bentham's description of the capsule, from Hartweg's specimens, we have 
only to add that it is often. nearly linear, 4 or 5 lines long, not much compressed, of a crusta- 
ceous texture, but at length dehiscent ; the valves bearing the many-seeded placentae. The ovoid 
seeds are apiculate at each end. The calyx, as in the next species, is very oblique at the orifice; 
in this it is narrow and prismatic, and its teeth are very short and obtuse. The marked 
difference between this species and E. Frémonti, and perhaps E. Tolmei, (which we have not 
seen,) led us to propose its generic separation, as Mr. Bentham has stated ; but his judgment in 
the combination is fully sustained by the characters of the following intermediate species.
