2. CONOPHOLIS, Wallroth. Squaw-root. Cancek-root. 



Flowers in a thick scaly spike, perfect, with 2 bractlets at the base of the irreg- 

 ularly 4 - 5-toothed calyx ; its tube split down on the lower side. Corolla tubu- 

 lar, swollen at the base, strongly 2-lipped ; the upper lip arched, notched at the 

 summit ; the lower shorter, 3-parted, spreading. Stamens protruded. Stigma 

 depressed. Pod with 4 placentae, a pair on the middle of each valve. — Upper 

 scales forming bracts to the flowers ; the lower covering each other in regular 

 order, not unlike those of a fir-cone (whence the name, from k&vos, a cone, and 

 <j)6Kis, a scale.) 



1. C. Americana, Wallroth. ( Orobanche American a, i.) — Oak woods: 

 not rare, growing in clusters among fallen leaves. May, June. — A singular 

 plant, chestnut-colored or yellowish throughout, as thick as a man's thumb, 3' - 

 6' long, covered with scales, which are at first fleshy, then dry and hard. 



3. PHELIPiEA, Toum. Broom-kape. 



Flowers perfect, crowded in a spike, raceme, or clustered panicle, with a pair 

 of bractlets at the base of the regular 4 - 5-cleft calyx. Corolla 2-lipped ; the 

 upper lip 2-lobed or notched ; the lower 3-parted. Stamens included. Ovary 

 with a gland at the base on the upper side. Pod with 4 placentae, two on the 

 middle of each valve. — Stems rather thick, scaly. (Named for L. ^ J. Phdi- 

 peaux, patrons of science in the time of Tournefort. ) 



1. P. Ludovici&na, Don. Glandular-pubescent, branched (3'- 12' high); 

 the flowers spiked in close clusters ; corolla somewhat curved, twice the length 

 of the narrow lanceolate calyx-lobes ; the lips equal in length. — Ilhnois {E. 

 Hall) and westward. Oct. 



4. APH'i'LLON, Mitchell. Naked Broom-kape. 



Flowers perfect, solitary on long naked scapes or peduncles, without bractlets. 

 Calyx 5-cleft, regular. Corolla with a long curved tube and a spreading bor- 

 der, somewhat 2-lipped ; the upper lip deeply 2-cleft, its lobes similar to the 3 

 of the lower lip. Stamens included. Stigma broadly 2-lipped. Capsule with 

 4 equidistant placentae, 2 borne on each valve half-way between the midrib and 

 the margin. Plants brownish or yellowish. Flowers (purplish) and scapes 

 minutely glandular-pubescent. (Name from a privative and cj>v\Xov, foliage, 

 alluding to the naked stalks.)— Perhaps rather a section of Phelipa;a. 



1. A. uni&6rum, Torr. & Gr. (One-flowered Cancer-root.) Stem 

 subterraman or nearly so, very short, scaly, often branched, each branch sending 

 up 1-3 slender one-flowered scapes (3' -5' high); divisions of the calyx lance- 

 awl-shaped, half the length of the corolla. (Orobanche uniflora, L.) — Woods : 

 not rare. April, May. — Corolla 1' long, with 2 yellow bearded folds in the 

 throat, the lobes obovate. 



2. A. fascieul&,tuin, Torr. & Gr. Scaly stem erect and rising 3' -4' out 

 of the ground, mostly longer than the crowded peduncles ; divisions of the calyx 

 triangular, very much shorter than the corolla, which has rounded short lobes. 

 (Orobanche fasciculata, iVuft.) — Islands in Lake Michigan (Engdmann), N. 

 Illinois ( Vasey), and northwestward. May.
