NOVITATES OCCIDENTALES. 45 
long and slender peduncles, these few and terminal or sub- 
terminal: petals white: stamens yellow, rather few: carpels 
puberulent, rounded, neither compressed nor margined, 
tipped with a long and slender straight or nearly straight 
beak, and arranged in an ovoid or more elongated head. 
Crevices of lava rock east of Willow Creek Valley in 
northern California, Mrs. R. M. Austin, 1894. Species evi- 
dently allied to R. glaberrimus, though very distinct by its 
slender habit, snow-white petals, and elongated head of 
achenes. 
Ranunculus caltheflorus. Stem solitary, stoutish, erect, 
6 to 15 inches high, dichotomous at about the middle, each 
fork ending in several subequal peduncles, and the whole 
inflorescence thus rather distinctly corymbose; herbage 
altogether glabrous except a few short hairs on the peduncles: 
radical leaves very few, ovate- and oblong-lanceolate, 1 to 3 
inches long, on petioles as long or longer, entire or irregu- 
larly somewhat toothed, the cauline narrower and mostly 
sessile: petals about 10, narrowly obovate-oblong, or almost 
spatulate-oblong: achenes in a depressed- globose small head. 
Plant of the Colorado Rocky Mountains chiefly, at eleva- 
tions a little below the limit of trees; the R. alismefolius, 
var. montanus of 8. Watson partly; also type of the unpub- 
lished R. alismeefolius, of Geyer. 
Ranunculus Hartwegi. RR. alismefolius, var. caule 
petiolisque basi hirsutis, Benth. Pl. Hartw. 295. R. alisme- 
folius, Gray, excl. var; also of Greene, Fl. Fr., not of Geyer. 
Geyer’s R. alismeefolius, never duly published, has been 
so variously misapplied in recent times that, asa name, it 
must be abandoned. Geyer’s specimens, on the labels of 
which he wrote this as a new name, were of the Rocky 
Mountain species which I now name R. caltheflorus. 
Bentham, who was the first to print the name, gave no des- 
cription at all of Geyer’s plant, but entirely perverted 
Geyer’s intended use of the name by applying it to that type 
which Torrey & Gray had called R. Flammula, namely, the
