nated as a new species, P. seorsus. On further reflection it seems better, 

 however, to consider them as representing merely a variety.

Pentstemon erianthera Whitedii, n. comb. — P. Whitedii 



Piper, Box. Gaz. 22:490. 1901. 



Mr. Piper, in Contrib. Nat. Herb. 1 1 : 500, reduces his species to a synonym 

 of P. erianthera Pursh, but this was hardly justified. P. erianthera Whitedii is 

 of different habit, producing several stems (instead of only 1 or 2) from a wood 

 taproot; the stems are more slender; the leaves narrower and more numerous; 

 the glandular-pubescence throughout is less pronounced ; the sepals are lanceo- 

 late, acute (not acuminate) ; the corolla is light blue without any of the peculiar 

 red found in typical P. erianthera. While the pubescence in the throat and on 

 the sterile filament is of the same character, it is far less copious. For these 

 reasons it seems that the northwest forms may well be carried as a variety of 

 the typical Rocky Mountain P. erianthera. 



Nelson and Macbride's no. 142 1, secured at Mackay, on gravelly sage- 

 brush slopes, July 30, 191 1, is typical of the variety.

Castilleja viscia Rydb. 



The range of this excellent species is greatly extended by Macbride's no. 

 990 from Silver City, Owyhee County. While Macbride's plants are not quite 

 typical, yet they help to a better understanding of the species. These are more 

 densely glandular and lack the crimson or scarlet tips in bracts and corolla. 

 The corolla is of the right proportions, but smaller. 



Castilleja multisecta, n. sp. — Freely branched from a woody 

 caudex, the ascending stems sparingly branched, 2-4 dm. high, 



including 



more 



third of the plant: pubescence inconspicuous, very softly lanate 



cm. loner, numerous 



5 



sometimes 



the undivided base obcuneate and strongly 3-nerved: bracts 

 resembling the leaves but the segments tipped with red, as are also 

 the margins of the galea: calyx more deeply parted above than 

 below, the primary lobes deeply toothed, the thin triangular teeth 

 acute: corolla slender, about 3 cm. long; the galea being about 

 one- third of this; the lower lip very short, saccate, its short broad 

 truncate teeth with a central cusp: seeds beautifully honey- 

 combed on the surface with shallow scarious cell walls.
