564 SCROPHULARIACE^E. Mimulus. 



Valley of the Sacramento to Plumas and Mendocino counties. The slender var. in Long Valley, 

 Plumas Co., JBolander. Much like the preceding, except in the points noted. Tube of the 

 corolla from 1 to 2 inches long ; the limb oblique, but the roundish lobes of the two lips nearly 

 equal, " pink with a deep crimson spot upon the base of each lobe, and a bright yellow stain along 

 the lower lip" (Lindley ; hence the name). Stigma of two broad and rounded"and mostly equal 

 lips, which are united so as to form when expanded a saucer : shaped disk. Capsule almost bony, 

 only 2 or 3 lines long, and about 2 lines wide, furnished with a groove at the septiferous suture 

 on the sides. Seeds double the size of those of M. Douglasii. It is well that Lindley's appro- 

 priate name is the earlier ; as there was a mistake in supposing this species to have been in Coul- 

 ter's collection. 



2. Corolla from tubular-funnelform to nearly campanulate ; its lobes about equal 

 in length : calyx campanulate or barely oblong, angled in the manner of 

 Mimulus proper : style gland^dar-pubescent above : stigma a peltate-funnelform 

 and entire or obscurely 2-lobed dilated disk : capsule between membranaceous 

 and coriaceous ; the valves in dehiscence bearing the placentue : dwarf or 

 low annuals, viscid-pubescent or glandular. EUNANUS, Gray. (Eunanus, 

 Benth. in part.) Closely connects the preceding section with true 

 Mimulus. 



* Small- and slender-flowered : corolla 3 to 6 lines long : calyx-teeth nearly equal. 



3. M. leptaleus, Gray. At length much branched, 1 to 3 inches high : leaves 

 from spatulate-oblong to lanceolate-linear (half an inch or less long) : teeth of the 

 campanulate calyx ovate or triangular, a quarter or one third the length of the tube, 

 a little shorter than the oblong-ovate obtuse capsule : corolla crimson-red, slender, 

 with filiform tube, little enlarged throat, and oblique limb (1| to 3 lines wide). 

 Proc. Am. Acad. xi. 96. 



Sierra Nevada, in gravelly soil, above the Yosemite, at about 6,000 feet (Miss Dix, Gray), 

 and Sierra Co., Lemmon. Capsule 2 lines long. 



* * Large-flowered for the size of tJie plant (an inch to a span high) : corolla 1 to 11 

 lines long, funnelform, with widely spreading limb ; the proper tube not much if at 

 all longer than the calyx : calyx hardly at all oblique, the teeth almost equal. 

 (Species seemingly too nearly related.) 



4. M. Bigelovii, Gray. An inch to a span high : leaves oblong and the upper 

 ovate, acute or acuminate : teeth of the calyx subulate (about 2 lines long when 

 well developed), half the length of the broadly campanulate tube ; the lower ones 

 shorter : corolla with cylindraceous or narrow throat and ample rotate-spreading 

 limb : capsule oblong-lanceolate, acute or acutish, a little exceeding the calyx, the 

 valves' membranaceous. Eunanus Bigelovii, Gray in Pacif. R. Rep. iv. 121. 



Gravelly hills and ravines, on the Mohave and Colorado (Bicjelow, Cooper), and Tejon (Xantus), 

 to Western Nevada (Bloomer, Torrey), and Southern Utah, Parry. Corolla crimson or purple, 

 with yellow centre. 



5. M. iianus, Hook. & Arn. From an inch to at length a span in height : 

 leaves from oblong or the lowest obovate to lanceolate : teeth of the calyx broadly 

 lanceolate or triangular, acute (a line long, fully one fourth the length of the tube) : 

 corolla (either deep crimson-purple or yellow) with narrow tube rather longer 

 than the calyx, and a gradually dilated funnelform throat : capsule with tapering 

 apex rather exceeding the calyx; valves chartaceous. Bot. Beechey, 378 (var. plu- 

 riflorus). Eunanus Tolmiati, Benth. 1. c. E.Fremonti, Watson, Bot. King Exp. 226. 



Var. (1) bicolor, Gray : a doubtful form, with throat of the corolla abruptly much 

 dilated and " dark purple, the limb yellow." Eunanus bicolor, Gray, Proc. Am. 

 Acad. vii. 381. 



Hillsides and banks, throughout the Sierra Nevada, extending more or less into the western 

 part of the State, and into Nevada, the eastern borders of Oregon, and to Wyoming. The greater 

 part of Hooker and Arnott's description of M. nanns relates to var. subuniflorus, i. e. to M. 

 Douglasii. The var. bicolor, from the higher parts of the Sierra Nevada in Fresno Co. (Brewer), 

 is known only from scanty young specimens, and may be quite distinct.
