GiMA (Navarretia) prostrata. G. leucncephalcE proxima, sed 

 humifusa cai)itiilo primario radical!, ramisque inferne iiiulis apice capi- 

 tulutn foliis iiivolucratum gerentibus quasi prolifera ; calycis tubo 

 parce hirsuto ; ovulis seminibusque in quoque loculo 4. — Near Los 

 Angeles, California, on tbe margin of desiccated ponds, Rev. J. C. 

 Nevin, 1879, 1881, Dr. Parry, 1881.* 



PiiACELiA Pringlei. Euphncclla, p. namatoidei proxima, gra- 

 cilior, glanduloso-pubescens, aperte ramosa ; foliis linearibus basi 

 attenuatis, inferioribus oppositis, omnibus pseudo-racemis gracilibus 

 brevioribus ; sepalis linearibus corolla fere rotata cterulea dimidio bre- 

 vioribus. — Mountains about the head-waters of the Sacramento 

 River, N. California, at 7,500 feet, Pringlc, 1881. This is interest- 

 ing as connecting the anomalous P. nnmatoides with the ordinary 

 Phacelias. Only one or two pairs of leaves are opposite ; the inflo- 

 rescence is as free from circination as in that species. 



PiiACELiA PLATYi.OBA. Euphcicelia inter species pi. m. glandu- 

 losas ncc setosas, gracilis, pube brevi molli subviscosa ; foliis parvulis 

 pinnato-o-partitis, segmentis oblongis crcnato-incisis, terminali majore 

 subpinnatifido ; floribus in spica angusta breviter pedicellatis subcon- 

 feitis ; calycis lobis e basi angusta valde dilatatis foliaceis (1 vel 2

* It has at length become evident that the unequal insertion of the stamens 

 (so characteristic of Phlox] will no longer serve to distinguisli CoHomia from 

 GiUa. Transitions occur in the same species from very unequal to equal inser- 

 tion, or nearer to equality than in some other Gilias besides those of the Navar- 

 retia section. The character of solitary cvules having also failed, nothing 

 remains but to remand Nuttall's genus Cnllomia to the already large and much 

 diversified genus Gilia. Fortunately not many new names will be required: 

 For the 



C. Cavanillcsiana, Don, is GiUa glomeriflora, Benth. 



C. CuvaniUesktna , Gray, as to the United States plant, is G. mnltijlora, Nutt., 

 from which one or two other species or forms are still to be extricated. 



C. Thurbert, Gray, has to be G. Thurberi. 



C. lonrjijlora, Gray, is G. lonrjijlora, Don. 



C. agjrcfjala, T. C. Porter, is G. agrjrefjata, Spreng. 



C. leptulea. Gray, is G. capiUans, Kellogg. 



C. licteropliijlla, Hook., is G. Sessei, Don. 



C- gilioides, Benth., with C. f/lutinosa, is G. divaricata, Nutt. 



C. gracilis, Dough, is G. gracilis, Hook. 



C. tenclla. Gray, may be named G. Icptotes. 



C. linearis, Nutt., can retain the specific name of G. linearis, and 



C grandijlora, Dough, that of G. grandijlora, the homonym of Steudel being 

 G. densijlora.
