GiLiA DiCHOTOMV, Bentli. I. c. Var. par\^flora : floribus multo minorihus ; coroUis inexpansis. 

 Cook's spring, and near Frontera^ Texas, March — April ; Bigehw^ Wright. About 6 iaclies 

 high. Leaves palmately 3-parted to the base; segments subulate and somewhat rigid. Corolla 

 much smaller than in the Californian plant, and it does not seem to expand. In other respects 

 I can find nothing to distinguish it. There are from 20 to 25 ovules in each cell of the ovary.

PoLEMOXiUM CCERULEUM, Linn.; Hook. Fl. Bor.'Amer. 2,^. 71. Banks of the Mimbres, New 

 Mexico, October, (in fruit); Bigehw. Stem 3 feet high, and, as well as the leaves glabrous. 

 Segments of the leaves 17-21, lanceolate^ acute, about an inch long. We find among our 

 numerous specimens of this polymorphous species^ some that accord very well with our New 

 Mexican plant.

•ward throughout the Mexican States to Sonora and California. (No. 495, 1585 and 1586, 

 Wright.) Very much branched, spreading or assurgent. Flowers pale purple, yellowish in 

 the throat. Our plant resembles a Chilian specimen of N. dichotoma received from Dr. Arnott 

 (which is part flowering), but differs from the description of Choisy in the corolla beii 



long again as the calyx. 



Yar. PAEViFOLiA : caule tenui laxiuscule ramoso ; foliis (semiuncialibus) obovatis obtusis basi 

 in petiolum brevem attenuatis ; floribus solitariis geminisque, pedicellis calyce dimidio longiori-

 Major Eaton, Annual. Stem very slender, dichotomously branching, purplish. Lower leaves 

 about half an inch long, abruptly narrowed at the base into a petiole which is less than half 

 the lamina ; upper leaves 3-5 lines long. Flowers nearly as in the larger variety.
