394 ADDITIONS AND CORRECTIONS. 



G. flavidulus, Chapm. Corolla sordid yellow, ovate in bud; lobes broadly oblong, 

 reticulated, 3 or 4 lines long : crown thinnish, equalling the stigma, 15-dentate ; teeth of 

 about equal length ; 5 broad, obtuse or retuse, alternate with 5 pairs of narrower subulate 

 ones; the sinuses deeper between those of each pair, which are accordingly rather distant.

 "C. aggregata, T. C. Porter, in Wiieeler Rep. ined. The character which appeared 



well to distinguish Cotloiiiia from Gilia, namely the unequal insertion of the stamens, 

 unfortunately fails in GUia aggrer/ata, Spreng. (Cantua agijreyata, Pursh), which on p. 145 

 is associated with G. coronopifolia, the type of the section Ipomopsis, and is in other respects 

 also a most polymorphous species. In many specimens, and we believe in the original, 

 the anthers are all of the same height and the insertion of the filaments equal, or not 

 obviously unequal: in others from all localities (but especially in the southern ranges of 

 the species), tlie insertion varies from obviously to excessively unequal, as much so as in 

 any Phlox. It seems impossible to divide the specimens into two or more species. As the 

 inequality prevails, and as the nearest relatives of the species have been already placed in 

 Collomia, it seems necessary to transfer GUia aggregata also to that genus, as has been 

 done by Professor Porter in the still unpublished Eeport of the Botany of Wheeler's 

 Surveys. 



Page 138, GILIA. After G. aurea, add : 

 ~G. Lemmoni. Of § DactglophjUum, with foliage of G.pus'dla, var. Californica,s.ni corolla 

 of the same, but more f unnelform and tube rather longer : stem erect, simple, 2 or 3 inches 

 high : leaves very much shorter than the internodes : flowers sessile in the manner of 

 Leptosiphoii, but few : calyx turbinate-prismatic, strongly 5-costate ; lobes aeerose-subulate, 

 rigid, equalling the yellow throat of the corolla : anthers oval . capsule narrowly cylindri- 

 cal, many -seeded. — S. E. California, in San Bernardino Co., Parry & Lemmon. Proper 

 tube of corolla, the yellowish throat, and the (apparently white) rounded-obovate lobes 

 each a line long. 



Page 160. PHACELIA. After P. orenulata, add : 



»P. Arizonica. Much smaller than P. crenulata, (with depauperate forms of which it has 

 been confounded), depressed instead of erect, lighter green; leaves oblong-linear or nar- 

 rowly oblong in outline, all but the lower sessile, deeply pinnatifid (6 to 15 lines long), 

 appressed-pubescent ; lobes oval or short^oblong, entire or crenulate : corolla only 2 lines 

 long, white, with some purple lines, rotate-campanulate ; the lobes quite entire : stamens 

 and style much exserted : capsule globular ; seeds oval. — S. Arizona, Thurber, Greene, &c. 



- P. Menziesii, p. 166, add : appendages of the corolla connivent in pairs over the base 

 of the midnerve of each petal, forming 5 nectariferous grooves alternate with the stamens. 



Page 193-196. ERITRICHIUM. 

 To the character of the subsection Eulcrynitzia, on p. 193, E. pusiltum forms an exception, 

 having acute-angled nutlets, as rightly described under the species. 



E. Texdnum, p. 195, has been collected in Colorado, at the base of the Eocky Mountains, 



by J. D. Hooker & A. Gray, 1877. 

 E. hol6pterum, p. 196. The wing of the nutlets appears to be sometimes reduced to a 



narrow border : but mature fruit is still unknown. The root is annual. 

 Var. SubmoUe, Gray. Low : inflorescence and obtuse calyx more canescently 



pubescent, nearly destitute of hispid hairs : immature nutlets merely wing-margined. 



Proc. Am. Acad. xiii. 374. — St. George, S. Utah, Palmer, 1877. 



B. setosissimum. Nutlets flattish or barely convex and not carinate on the back. 

 Those of E. glomeratum are distinctly carinate. 



Page 210. CONVOLVULUS : add : 



C. Havanensis, Jacq. Suffruticose, prostrate, canescent and glabrate : leaves oblong 

 or elliptical, obtuse or retuse and mucronate, entire (6 to 12 lines long), abruptly contracted 

 or sometimes tapering into a short petiole : peduncle few-several-flowered : pedicels longer
