442 SUPPLEMENT. 



P. l^tus, Gray, p. 272. Sepals oblong to ovate-lauceolate, and from hardly acute to 

 acuminate. 



Var. leptosepalus, Greene, in herb. Sepals long-acuminate from a broadish base, 

 or linear-attenuate (4 or 5 lines long), loose : occurs both with narrow linear-lanceolate and 

 with broader lanceolate leaves. — Butte Co., California, Mrs. Austin. 



P. ceesius, Gray. Next to P. Roezli. Low, a span to a foot high from a cespitose lignes- 

 ceut base, glabrou.s up to the peduncles, glaucesceut or glaucous : leaves coriaceous, vein- 

 less; radical and lower caulinc orbicular or subcordate or spatulate-obovate (half or two- 

 thirds iuch long), abruptly contracted into an equal or longer petiole ; upper cauline one or 

 two pairs, narrow and sessile ; thyrsus loose and few-flowered : sepals oblong, pruinose- 

 glandular, as also tlie short pedicels and occasionally the longer peduncles : corolla violet or 

 purple, barely three-fourths iuch long, tubular v.ith slight enlargement upward, and with 

 very short lobes. — Proc. Am. Acad. xix. 92 — Rocks in the San Bernardiuo Mountains, 

 S. E. California, Parry & Lemmon, W. G. Wright, Parish. 



P. Cusickii, Gray. Of the Saccanthera section, before P. Kiwjii, p. 272. A foot or less 

 high, many -stemmed from a barely lignescent caudex, strict, pale and very minutely prui- 

 nose-puberulent, equably leafy up to the racemiform loose thyrsus : leaves very narrowly 

 linear (an inch or two long, little over a line widS), or some of the lower broader and spatu- 

 late : peduncles 1-2-flowered : sej)als ovate, acuminate, glabrous, not glandular: corolla 

 barely three-fourths inch loug, briglit blue with a purple tube, a moderately enlarged throat, 

 and short lobes: sterile filameut spatulate-dilated at tip, very glabrous. — Proc. Am. Acad, 

 xvi. 106. — N. E. Oregon, on the slopes of Powder River or Eagle Creek, Cusick. 



P. Cerrosexsis (which should have been Ceilrosensis), Kellogg, Proc. Calif. Acad. ii. 19, & 

 Bull. i. 145, with plate (see p. 273), from Cedros Island, off Lower California, proves to be a 

 good species, and P. brevilabris, Gray, Proc. Am. Acad. xvii. 229, is a synonym. Color of corolla 

 uncertain, but purely not "yellow." 



P. CANOSO-BARBATUM, KcUogg, has beeu identified by Mrs. Curran (in Bull. Calif. Acad. i. 

 145) with P. hrti-iflorus, Lindl., and P. rostrifeokum with P. Brid(jesii: but in the description 

 the color of the flowers of the two has been exchanged. 



P. TENELLUS, Kcllogg, Proc. Calif. Acad. i. 56, is by the same authority said to be P. azur 

 reus, Beuth., probably depauperate. 



13. MiMULUS, L. P. 273. 



Revised in the light of E. L. Greene's new arrangement in Bull. Calif. Acad. i. 94-123 

 (Mimuliis, Eununus, Diplacus), of recent personal observations, and of the original types of 

 Bentham, Hooker, &c., in the Kew Herbarium. Polymorphous, but better retained entire under 

 five subgenera than divided into as many genera. Diplacus is placed first, as having the best 

 claims to generic distinction, being shrubby. 



§ 1. Diplacus, p. 275. Add char. : Capsule firm-coriaceous, narrow, syiu- 

 metrical, tardily dehiscent down the upper suture, only after seed-shedding, also 

 later by the lower suture into the two placentiferous valves : yet in some plants 

 simultaneously dehiscent into the two valves. Seeds elongated-oblong. Pubes- 

 cence when developed partly of branching or somewhat aspergilliform downy 

 hairs. 



M. glutinosus, Wenbl. Corolla from orange or salmon-color to pale buff. Var. linearis 

 is the most narrow-leaved form, in arid exposures, as Diplnms latifvlivs is the broader- 

 leaved and luxuriant extreme. Var. hrachi/pns is the best-marked form, on account of the 

 villous (but deciduous) hairs of the calyx and generally pale corolla. 

 M. puniceus, Stkud. {D. qlutinosus, var. pnniceiis, and part of var linearis, p. 275), com- 

 monlv tall and narrow-leaved, with brick-red or blood-red rather than scarlet corolla, and 

 only in Southern California, may be regarded as a species until intermediate colors are 

 met with.
