444 SUPPLEMENT. 



Eunanus Douglasii, Benth. PI. Hartw. no. 1894 (excl. ripe fruit described, which is of M. 

 tricolor) ; Gray, Pacif. R. Rep. iv. 120, mainly, not Benth. in DC. E. Kelloggii, Curran, in 

 Greene, Bull. Calif. Acad. i. 100. — Common through middle parts of California. Mis- 

 taken by Bentham and myself for a later and caulescent form of M. Douglasii, first and 

 well discriminated by Mrs. Layne-Curran. 



4— -i— Ambiguous species, with corolla of § Eunanus, and little exserted, but with oblique late- 

 dehiscent capsule of § CEnoe. 



M. latifolius, Gray, p. 274. Extra-limital. The capsule in plant raised from Palmer's 

 seeds appears to be only moderately oblique, linear-oblong, obtuse, and not indurated ; but 

 as now received from Mr. Greene, from its native habitat, and fully mature, it is lanceolate, 

 strongly oblique, and as if bent on its broad base ; the upper carpel much larger than the 

 other, very gibbous and sharp-edged dorsally, and there very tardily dehiscent. 



§ 3. Eunanus, Gray, Bot. Calif. Corolla from tubular-funnelform to nearly 

 campanulate, with either obscurely or manifestly bilabiate limb, the proper tube 

 either moderately exserted or included in the campanulate or oblong calyx : style 

 glandular-pubescent above : stigma usually peltate-funnelform, obscurely 2-lobed 

 or entire : capsule symmetrical, from firm-chartaceous to membranaceous, dehis- 

 cent by both sutures into two valves, which bear the separated placenta; : low or 

 occasionally taller annuals, most of them glandular- or viscid-pubescent and 

 heavy -scented. 



* Corolla only a quarter-inch long, slender, only slightly exserted out of the broad and ventricose 

 calyx until elevated on the growing capsule: valves thin-chartaceous. 



M. Rattani, Gray. Viscid-pubescent, a span or two high : leaves oblong ; upper about 

 equalling the sessile flowers : calyx very viscid, when fructiferous little higher than broad, 

 a little oblique at orifice, and with short ovate teeth : corolla rose-purple, its lobes barely a 

 line long, equal except that the upper are united to near the middle : capsule narrowly 

 ovate-lanceolate, nearly half exserted : seeds oblong-oval. — Proc. Am. Acad. xx. 307. 

 Eunanus Rattani, Greene, Bull. Calif. Acad. i. 105. — Lake and Colusa Co., California, 

 Rattan, Layne-Curran. 



* * Corolla a quarter to three-fourths inch long, f unnelform or narrower, well exserted beyond 

 the campanulate or oblong calyx: capsule-valves membranaceous or chartaceous: plants a span 

 or two high and branching when luxuriant, when depauperate dwarf and simple, beginning to 

 blossom from near the root. 



•)— Calyx not manifestly oblique at orifice, but lower teeth usually a little shorter. (Species of 

 difficult discrimination.) 



M. tnephiticus, Greene. Very viscid-pubescent and strong-scented : leaves from ob- 

 ovate-oblong to nearly linear : calyx-teeth short, broadly lanceolate, acutish : corolla half to 

 two-thirds inch long and with somewhat bilabiate limb 4 or 5 lines broad, bright yellow, 

 often purple-dotted in the throat, sometimes whole throat or even the limb turning reddish : 

 seeds oval. — Bull. Calif. Acad. i. 9. Eunanus mephiticus, Greene, Bull. Calif. Acad. i. 102. 

 — Common in the Sierra Nevada from the Yosemite northward. 



M. nanus, Hook. & Arn. Puberulent and somewhat viscid, or low and early-flowering 

 plants almost glabrous : leaves obovate and spatulate-oblong, all with tapering base : calyx- 

 teeth broadly lanceolate or triangular, acutish or when outspread obtuse, but acute when 

 the tips are conduplicate, a quarter or a third the length of the oblong tube : corolla rose- 

 purple with darker or yellow throat, mostly two-thirds or three-fourths inch long ; the limb 

 half-inch or less wide, evidently bilabiate and the lower lip a little shorter than the upper : 

 seeds oval-oblong. — (Supra, p. 274, excl. the yellow-flowered form and the var.) California 

 to interior of Washington Terr, and Wyoming, first coll. by Tolmie. 



M. Bigelovii, Gray, p. 274. Viscid-pubescent, sometimes viscidly villous : leaves nearly of 

 the preceding or more acute, the upper ovate and acuminate : calyx-teeth triangular and 

 acuminate or subulate-acute, about half the length of the tube : corolla crimson, sometimes 

 with a yellow eye, three-fourths inch long when well developed, narrow up to the abruptly
