442 SUPPLEMENT. 



P. leetus, Gray, p. 272. Sepals oblong to ovate-lanceolate, and from hardly acute to 

 acuminate. 



Var. leptosepalus, Greene, in herb. Sepals long-acuminate from u 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. OEesius, Gray. Next to P. Eoezli. Low, a span to a foot high from a cespitose lignes- 

 cent base, glabrous up to the peduncles, glaucescent or glaucous : leaves coriaceous, vein- 

 less; radical and lower cauline orbicular or subcordato or spatulate-obovate (half or two- 

 thirds inch 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 the short pedicels and occasionally the longer peduncles : corolla violet or 

 purple, barely three-fourths inch long, tubular with slight enlargement upward, and with 

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

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



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

 high, many-stemmed from a barely lignescent caudex, strict, palo 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 wide), or some of the lower broader and spatu- 

 late : peduncles 1-2-flowered : sepals ovate, acuminate, glabrous, not glandular : corolla 

 barely three-fourths inch long, bright blue with a purple tube, a moderately enlarged throat, 

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

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



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

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

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

 uncertain, but surely not "yellow." 



P. canosckbarbatttm, Kellogg, has been identified by Mrs. Curran (in Bull. Calif.Acad. i. 

 145) with P. breviflorus, Liudl., and P. rostriflorum with P. Bridgesii: but in the description 

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



P. tenellus, Kellogg, Proc. Calif. Acad. i. 56, is by the same authority said to be P. azu- 

 reus, Benth., probably depauperate. 



13. MlMULUS, L. P. 273. 



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

 [Mimulus, Eunanus, 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, sym- 

 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, Wendl. Corolla from orange or salmon-color to pale buff. Var. linearis 

 is the most narrow-leaved form; in arid exposures, as Diplacus latifolius is the broader- 

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

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

 M. punioeus, Steud. [D. glutinosus, var. punieeus, and part of var. linearis, p. 275), com- 

 monly 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.
