4 PLANTS BAKERIAN^E. 



CALTHA CHIONOPHILA, Greene, Pitt. iv. 80. Two repre- 

 sentations of this; n. 227, from the Grand Mesa, shows con- 

 stricted but not dentate foliage, while n. 408, from Carson, 

 has the leaves smaller, more rounded, and notably dentate. 



TROLLIES ALBIFLORUS, Rydb. Fl. Mont. 152. Under n. 

 221 we have excellent flowering specimens of this fine plant 

 which Mr. Rydberg has well separated altogether, in name 

 and rank, from T. laxus. 



DELPHINIUM NELSONII, Greene. On open hillsides at 

 Cerro, n. 52, the usual form; n. 216, the largest and most 

 showy specimens yet seen, said to be abundant in open 

 parks at Van Boxle's, above Cimarron. 



DELPHINIUM DUMETORUM. Near the last, but more 

 slender and commonly 2 feet high or more; leaves remote 

 and with fewer and broader segments; herbage glabrous; 

 ramifications of the root more slender and disconnected: 

 flowers smaller and less widely expanding, though with 

 spur longer and more slender, acutish and strongly curved 

 downward at the end, the color of the whole flower a pale 

 lavender-blue: follicles puberulent, shorter and more widely 

 spreading than in D. Nelsonii. 



On dry hills, among shrubbery above Cimarron, 6 June, 

 n. 35; growing quite apart from D. Nelsonii, which occupies 

 open grassy ground at higher elevations. 



DELPHINIUM QUERCETORUM. Resembling D. glaucum, 

 perhaps as tall, with equally leafy stem and narrow con- 

 densed raceme; herbage pale and glaucescent, but only the 

 stem and petioles truly glabrous, the leaves villous-puber- 

 ulent, their 3 to 5 segments broad -cuneiform and 3-lobed, not 

 toothed ; rachis of the spike strongly hirtellous, the pedicels
