__ Mr. Thomas Howell has this year found Carex cinnamomea, 
Olney, at Grave Creek, Southwestern Oregon. This is the sec- 
ond known locality for the species. It was first found by Bo- 
lander (No. 6477) on the Red Mountains, Mendocino county, 
Cal. In some of the specimens the perfgynium is minutely pub- 
escent above the middle. The pubescence is evidently deciduous 
with age. 
CARICES UNKNOWN TO AMERICA. 
Inthe Preliminary Catalogue of the Plants of Lieut. Wheeler’s 
Expedition (1874), Mr. Olney introduced the following exotic 
Species upon specimens collected by the survey : 
C. levirostris, Blytt and Fries, upon a specimen of C. utricu- 
lata, Boott. (No. 1068. 
C. turfosa, Fries, upon ©. vulgaris, Fries. (No. 1039.) 
“CO. personata, Fries,” upon C. aquatilis,Wahl., var. sphag- 
nophila, Fries. (Nos. 1037 and 1038 ) Mr. Olney probably 
referred to C. acuta, L., var. personata, Fries. 
_ C. alpina, Swartz, var. nigrescens, Anderss., upon C. alpina, 
(No. 1044.) ‘The form referred to Andersson’s variety will not 
fall under the character “spicis omnibus sessilibus, atrofuscis ; 
pumila, rigidula,”—Anderss. Cyp. Scand 
C. sempervirens, Vill.? Carex Cat., is C. frigida, All. 
_ C. obesa, All., is represented in this country only by its var. 
minor, Boott. 
On a New Mimulus of a Peeuliar Section of the Genus. 
: BY J. G. LEMMON. 
Mimulus: Mohavensis is the name under which I sent speci- 
mens of this interesting little plant to Prof. Gray. It is so pecu- 
liar that he was at first disposed to regard it as a new genus, But 
48a related species afterwards received from another source ap- 
peared to invalidate the characters relied on, he accepted the view 
which I had taken of it, and drew up the following character of 
4 new section of the genus, which was needed for its reception : 
. . § MIMULASTRUM. Corolla with cylindrical tube and throat 
included in the turgid 5-angled unequally toothed calyx, gibbous 
nteriorly near the base; the orifice contracted ; limb rotate, re- 
«ected, almost regularly 5 cleft; lobes flabelliform-dilated, sim- 
a" Pea dg that the two posterior are slightly smaller. Character 
. abit of section Eunanus, except in the capsule, the submem- 
ranaceous valves of which are placentiferous.”
