nearCruces; Bigeloio. Gila valley; Sclwtt. Napa county," California ; Thurler. San Luis 

 Obispo ; Parity. The capsule of this species accords with the generic character, as given by 

 Bentham^ (fee, except that the membranaceous valves scarcely, if at all, separate from the undi- 

 vided placenta^ but remain coherent by means of the thin and short partitions. 



MiMULUS GLABRATUS, H. B. K. Nov. Gen. d Spec, 2, p. 370 ; Benth. I. c. Copper Mines and 

 Mimbres, New Mexico; Bigeloio; Wright., (\M2,) &c. Ojo Francisco and Tucson, Sonora ; 

 Parry & Capt. S. K. Smith, Texas ; Wright & Lindheimer. This appears to vary as much 

 in size and aspect, and to have nearly as large a geographical range as M. luteus ; and M. 

 Jamesii is pretty plainly no more than a smaller flowered and almost entire-leaved northern 

 form of it. 



MiMULus BREViPES, Benth. Scroph. Ind. 2, adnoi:^ & in BG. Prodr, 10, p. 369. Near San Diego, 

 California, May; Ihurher^ Parry ^ etc. Chiefly narrow-leaved forms, the same as Coulter's No. 

 640. Bentham indicates it as perennial, but our Douglasian specimens show an annual root ; 

 so do those of Thurber. The capsule of this species is ovoid-lanceolate, rather firm and chartace- 

 ous in texture, loculicidal and splitting through the axis, separating the two placentie, which 

 remain adnate to the valves, just as in Diplacus. Through M, rubellus, etc., there is a regular 

 radation as to the dehiscence between this and the Mimuli with a thin and membranaceous 

 capsule, and a fleshy placenta, which shows no disposition to split. 



MiMULUS CAEDINALIS, Dougl 



Ne 



California; Parry. The valves of the capsule with the partitions in this species tardily separate 

 from the axis, from which the two placentae are pretty widely separated, being projected far 



into the cells. 



MiMULUS RUBELLUS, (sp. nov ) : tenellus, erectus, e radice annua ramosus, viscido-puberulus ; 



foliis anguste oblongis lanceolatisve trinervibus fere integerrimis basi angustatis sessilibus ; 

 pedunculis folium plerisque superantibus ; calycis oblongi dentibus brevibus aequalibus, ore 

 aequali ; coroll^e purpurea© tubo haud exserto. — Wet ravines of the Organ mountains and 

 Copper Mines, April ; Bigeloio^ Wright^ (1483,) and Hueco mountains; Thurher, (135.) Plant 

 2 to 6 inches high. Leaves 3 to 8 lines long, the uppermost acutish. Calyx perfectly equal at 

 the summit, even in fruit, 3 lines long, narrow. , Tube of the corolla yellowish, the limb 1^ 

 line long, pink or purple. The valves of the capsule are pretty thin and delicate; but the 

 jdacenta splits at the summit in dehiscence, or is bipartible, one half remaining adnate to each 



valve. 



MiMVLLS (Diplacus, Nutt.) glutinosus, Wendl. Ohs.^ p. 51. San Francisco, Monterey, and 



San Diego, California. In various forms^ and both with red and yellow flowers. Several 

 annual Mimuli being dehiscent through the placenta in the same way as the present plant, there 

 appears to be no ground for viewing Diplacus as anything more than a marked section of 

 Mimulus, distinguished by its shrubby habit, glutinous foliage, and narrow pods of a firm 



texture. 



Eunaxus Fremonti, Benth. in DG. Prodr. 10, p. 374? Dry gravelly places near Monterey, 



Mav Parry. Only a single and miserable specimen was gathered. It seems likely to be a 

 state of E. Fremonti, or possibly of Douglasii, with a remarkably abbreviated corolla. 



Herpestis cham^drioides, E. B. K. Nov. Gun. d Spec. 2, p. 369. Santa Cruz, and Sierra 

 Yerde Sonera- Wriaht^ (1484,) SchotL Also a variety with simpler and less spreading stems,
