480 GENTIANACE.E. Erythrcca. 



3. E. floribunda, Benth. More slender and inflorescence more open : lobes 

 of the light ro.se-culored corolla oblong, becoming lanceolate in age, hardly 2 lines 

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

 lobes more subulate and less carinate than in the preceding. — PI. Hartw. 322. 



Valley of the Sacramento, Hartwcg. Also, in a dwarf and fewer-flowered fonu, Sierra Valley, 

 Lemmon. 



* * * Corolla-lobes (1| to 3 lines long) much shorter than the tube: seeds globular: 

 anthers oblong : flowers sparsely paniculate or solitary, peduncled. 



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

 from the base : leaves mostly oblong, obtuse, and about half an inch long : peduncles 

 mostly shorter (sometimes much shorter) than the flowers : lobes of the rose-red 

 corolla oval, very obtuse, becoming oblong (often 3 lines in length). — E. Muh.len- 

 ba-gii, Grisebach, 1. c. as to Californian plant only ; Benth. PL Hartw. 322. 



Hills, Monterey to San Francisco Bay, not uncommon. The Pennsylvanian plant, on which 

 Grisebach mainly founded his E. Muhlenbergii, is E. ramosissivia, introduced from Eui'ope ; but 

 the name may be kept up for the Californian species, although meaningless, as Muhlenberg had 

 nothing to do with it. 



5. E. Douglasii, Gray. Mostly 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 fihform, commonly strict and the earlier or central ones an inch long or 

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

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

 bach in Hook. PL ii. C9, t. 157, A. Erythraea Nuttallii, Watson, Bot. King Exp. 

 276, in part. 



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

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 Neither of Nuttall's unpublished names 

 {E. tenella for a dwarf state, and E. elata for a taller one) seems appropriate : so we have imposed 

 the name of the first collector, Douglas. 



E. Nuttallii, Watson (Bot. King Exp. 276, t. 29 mainly), is distinguished from E. Douglasii 

 by the acutish lobes of the 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, Nuttall, H. Engelmann. Although two of the three of Nuttall's un- 

 published names, cited by Watson under E. NuttaUii, belong to the plant now distinguished as 

 E. Do2iglasu, yet Mr. Watson's figure and description relate mostly to the species for which the 

 name is here retained. 



2. MICROCALA, Link. 

 Calyx 4-toothed, 4-8-ribbed. Corolla short-salverform, withering persistent on 

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

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

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

 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-flowered, or branched at base, with one to three pairs of minute oval or oblong 

 leaves below : peduncle strict and naked, quadrangular : calyx short, strongly quad- 

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

 teeth distant and very short : corolla salfron-yellow, barely twice the length of the 

 calyx, open only in bright sunshine, closing in the afternoon. — DC. Prodr. ix. C3 ; 

 Progel in Fl. Bras. vi. 213, t. 58, f. 3. Exacicm quadrangular e, Willd. E. infla- 

 tum. Hook. & Arn. Cicendia quadrangularis, Grisebach, Gent. 157. 



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

 have been introduced ; but also on the coast near Mendocino {Bolander), under Piims contorta ; 

 so that it may be indigenous.
