SCROPHULARIACE^E. (FIGWORT FAMILY.) 281 



1. P. I-udoviciana, 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. Illinois 

 (Mr. E. Hall) and westward. Oct. 



4. APIiYL,L,ON, Mitchell. NAKED BROOM-RAPE. 



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 mi- 

 nutely glandular-pubescent. (Name from a privative and <j)v\\ov, foliage, allud- 

 ing to the naked stalks.) Perhaps rather a section of Phelipaea. 



1. A. uniflorttin, Torr. &Gr. (ONE-FLOWERED CANCER-ROOT.) Stem 

 subterranean 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; 

 rather common. April, May. Corolla 1' long, with 2 yellow bearded folds in 

 the throat, the lobes obovate. 



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

 out of 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, Nutt.) Islands in Lake Huron (Engelmann), and north- 

 ward. May. 



ORDER 74. SCROPHULARIACE^E. (FIGWORT FAMILY.) 



Chiefly herbs, with didynamous or diandrous (or very rarely 5 perfect) sta- 

 mens inserted on the tube of the Z-lipped or more or less irregular corolla, the 

 lobes of which are imbricated in the bud : fruit a ^-celled and usually many- 

 seeded pod with the placenta? in the axis : seeds anatropous with a small em- 

 bryo in copious albumen. Style single : stigma entire or 2-lobed. Leaves 

 and inflorescence various ; but the flowers not terminal in any genuine rep- 

 resentatives of the order. A large order of bitterish, some of them nar- 

 cotic-poisonous plants, represented by two great groups (which are not differ- 

 ent enough to be classed as suborders*) ; to which an anomalous genus 

 (Gelsemium) is appended, since no better place has yet been found for it. 



* The technical distinction between the so-called suborders is principally in the aestivation 

 of the corolla, which is not likely to be entirely constant. Some years ago, my former pupil, 

 Mr. Henry James Clark, showed me that in Mimulus one or both of the lateral lobes of the 

 lower lip are occasionally exterior in the bud, and I have since noticed a similar exception in 

 anomalous Pectstemon. 



The plants of Tribes 8, 9, and 10 (which incline to turn blackish in drying), are most, if not all, 

 of them partial root-parasites. This has been for some time known in Tribe 10 ; and has lately 

 been shown to b the case in Gerardia also, by Mr. Jacob Stauffer, of Mouut Joy, Pennsylvania-
