3. E. floribunda, Deiitli. More slouJur and inllorescence more open : lobes 

 of tho liyliL rDsu-culorcil corullii oblong, becoming lanceolate in age, liartlly 2 lines 

 long, only a third or one Iburtli tho length of the tube : anthers oblong : calyx- 

 lobes more subidato and less carinate than in the preceding. — PI. llartw. 322.

 Lciiiinoii. 



* * * Corolla-lobes (\h to 3 lines long) much shorten' than the tube: seeds ylobvlar: 

 anthers oblony : Jloivers sparsely paniculate or solitary, peduncled. 



4. E. Muhlenbergii, (Jrisebach. Two inches to a span high, simple or branched 

 from the base: leaves mostly oblung, obtuse, and about half an inch lung: peiluncles 

 mostly shorter (sometimes much shorter) than the llowers : lobes of the ruse-red 

 corolla oval, very obtuse, becoming oblong (often 3 lines in length). — A\ Muhlen- 

 beryii, Grisebach, 1. c. as to Caliiuruiau plant unly ; Eenth. PI. Hartw. 322. 



Hills, Monterey to Sau Francisco Hay, not uncommon. The Pennsylvanian plant, on which 

 Grisebach mainly loumled liis E. M aklcnbcnjii, is E. rainosissima, introduced horn Europe ; hut 

 the name may be kept uji for the L'alifornian species, although meaningless, as Muhlenberg had 

 nothing to do with it. 



5. E. Douglasii, Gray. IMostly slender, from 2 to 12 inches high, loosely 

 paniculate : leaves lanceolate or linear-lanceolate and acute, or the lower ones nar- 

 rowly oblong (from half an inch to nearly an inch in length) : peduncles long 

 and lilil'orm, commonly strict and tlie earlier or central ones an inch long or 

 more: lobes of the pink corolla oblong (l)arely 2 lines in length): seeds globular, 

 hardly a cpiarter of a line long. — Cicendia exaltata (wrongly characterized), Grise- 

 bach in Hook. Fl. ii. CD, t. 157, A. Erythrcea NuttaUii, Watson, Bot. King Exp. 

 276, in part. 



Along the eastern borders of tho State from Fort Mohave northward, and sparingly on the 

 western : also in Oregon, Idaho, and Noithern Utah. Neither of Nuttall's unpublished names 

 {E. tenella for a dwarf state, and E. elala for a taller one) seems aj)propriate : so we have imposed 

 the name of tho first collector, DoikjIus. 



E. NiiTTAi.i.il, "Watson (Hot. King Kxp. 276, t. 29 mainly), is distinguished from E. Douiihisii 

 by the acutish lobiis of tho commonly larger corolla, and the oblong seeds, which are fewer and 

 much larger, a third of a line long. It occurs in Nevada, as near as Ruby Valley, and in adjacent 

 parts of Idaho and Utah, Nuttidl, H. Eiii/clmann. Although two of the three of Nuttall's un- 

 published names, cited liy AVatson under E. NutUdlii, belong to the plant now distinguished as 

 E. Douglasii, yet Mr. Watson's figure and description relate mostly to tho species for whicii the 

 name is here retained. 



2. MICROCALA, Link. 

 Calyx l-toothcd, 4-8ribbed. Corolla shortsalverform, withering persistent on 

 tlio ovoid capsule, Stamens short, inserted in the throat : anthers round-cordate. 

 Style liliform, in ours persistent or tardily deciduous : stigma peltate-dilated, at 

 length separating or separable into 2 broad plates. Seeds, &c., as Erythrcea. — 

 Little annuals, one in the Old World, and one or two in South America, whence 

 the following may have reached California. 



1. M. quadrangulariS, Grisebach. An inch or two high, filiform, simple and 

 one-llowercd, or briinclicd at basi;, with one to three ]);iirs of minute oval or oblung 

 leaves i)clow : peduncle strict and naked, tjuadraiigular : calyx short, strongly qmid- 

 rangular, and as it were truncate at bottom and tup, at least when in fruit ; the 

 teeth distant and very short : corolla sall'ron-yellow, barely twice the length of the 

 calyx, open only in briglit sunshine, closing in the afternoon. — DC. Prudr. ix. 03 ; 

 Prugel in Fl. Bras. vi. 213, t. 58, f. 3. Exacum quadranyulare, Willd. E. injla- 

 ium, Hook. &, Am. Cicendia quadranyularis, (-Jrisebach, (ieut. 157. 



Hillsides and moist meadows about 8an Francisco, Martinez, and Vallejo, where it may readily 

 have been introduced ; but also on the coast near Mendocino {Bolaiider), under Finus coiUorla ; 

 so that it may be imligfuous.
