54 AMERICAN MIDLAND NATURALIST 



cm. lata, in ramis et ramulis minora, lanceolata, vel anguste 

 elliptico-lanceolata, vel etiam oblonga, glabra, viridia superiore 

 facie, pallida vel glaucescentia inferiore. Folia cum venis divar- 

 icatis, apice acuminato aristato, (arista saepe 5 mm. longa, vel 

 longior) basi cuneato vel etiam anguste cuneato. Petioli circa 

 5 mm. longi; internodi 2.5-6 cm. longi. Pedunculi circa 1.5 cm. 

 longi, et pedicelli 2-4 mm. longi cum bracteis scariosis linearibus 

 ad basim ornati. Flores pauci tubulati 3 mm. longi et i mm. 

 lati in caulis summitate tantum aggregati. (Quando vero flores 

 in prima inflorescentia vel defloruerunt vel jam lobos fecerunt 

 adhuc submaturos, deinde alii quidam (2 vel 3) cymi in ramis 

 apparent^) CoroUae segmenta i mm. longa, margine involuti, 

 triangularia, incurvata etiam arescentibus post floribus. Sepala 

 anguste lanceolata vel aristiformia supra mediam partem. Lobi 

 circa 13 cm. long (adhuc quidem immaturi) et verisimiliter per- 

 pauci. 



Plant probably and apparently a meter high rather leafy, 

 glabrous, with greenish stems and rather numerous long red or 

 reddish branches. Branches and twigs much exceeding the ter- 

 minal inflorescence (about 3.5 dm.) Leaves of the stem 9-10 cm 

 long and 2-2.5 cm. wide, smaller and suberect on the branches, 

 lanceolate or narrowly elliptic-lanceolate or oblong, green above 

 pale or glaucescent beneath with veins diverging from the mid- 

 rib. Apex acuminate, plainly aristate, bristle sometimes 5 mm. 

 long or more. Base cuneate or sharply and narrowly so. Petioles 

 about 5 mm. long; internodes 2.5—6 cm. long. Peduncle about 

 1.5 cm. long at flowering and much longer in fruit. Pedicels 2-4 

 mm. long arising from a number of scarious bracts at the base. 

 Flowers few (about 12 or 13) tubular 3 mm. long, i mm. wide. 

 Inflorescence strictly terminal to the main stem and 2 or 3 others 

 produced only later when the terminal has run to fruit or failed to 

 produce fruit. Corolla segments triangular involute on the margins, 

 scarcely opening, never spreading in the slightest manner, nearly 

 I mm. long. Sepals narrowly lanceolate or apparently aristate 

 beyond the upper half. 



Pods few, 13 cm. long (in the specimen still immature.) 



This plant belongs to the Cannahinum group, but is not closely 



related to A. cannahinum itself. The type of the species consists 



of two sheets, No. 10563 of my herbarium, sent me from somewhere 



near Detroit, Mich., by Mr. R. Carolin. This enthusiastic collector
