 the lower ones more or less pedicelled, longer calyx-lobes, aud very woolly anthers. It may also 

 reach California.

 spreading lobes : anthers glabrous or nearly so : stems from a thick and jinn iuh r-

A. PINETORUM, Gray (Pheliptea pinelorum , Gray, 1. c, and Orobanche jiiiirtiirini), Gcyerin Hook. 

 Kew lour. Bot. iii. 2!*7), of the Columbia River region, another species of this section, has more 

 tapering stems and a looser panicle, often a foot high, and equal calyx-lobes rather shorter than 

 its tube. 



2. BOSCHNIAKIA, C. A. Meyer. 



Calyx short and cupshaped, oblique, or tho upper side truncate, the lower side 

 with about 3 distant teeth : no bractlets at its base. Corolla ventricose ; the upper 

 lip erect or somewhat arched and entire ; the lower 3-parted, sometimes very short. 

 Stamens somewhat protruded : anthers blunt at base. Seeds with a thin and retic- 

 ulated coat. — Short and stout simple sbins from a tuberous has.', thickly beset 

 with scales, glabrous throughout; the flowers in a dense scaly spike, yellowish or 

 brownish. — Bongard, Veg. Sitcha, 1">S.

 inhabit and the high northern parts of this continent. It is remarkable for the ex- 



tre ly short lower lip to the corolla. 



B. II i 1:1, Walp. (figured by Hooker as Orobanche tuberosa), known only by a specimen 



collected by Menzieaon the X. W. Coast, must be near the following, but has short and blunt 

 calyx-teeth and narrow bracts to the spike. 



1. B. strobilacea, Gray. A span high, thick and stout, with broad and 

 rounded dark-brown scales overlying one another, so as to resemble a spruce-cone, 

 Boriferous from uear the base: calyx truncate-entire on the posterior side, on the 

 anterior with ."> linear-subulate teeth longer than the tube ; lower li|> of the corolla 

 as long as the upper, of 3 oblong spreading lobes: filaments strongly bearded at 

 base: placentae I, equidistant. — Pacif. I.'. Rep. iv. 118.
