292, TEUCRIUM. /,. JAtit. Gen. 495. 

 [Named from Teucer, a Trojan Prince,— who, it is said, first used the plant.] 



Calyx tubular-campanulate, near equally 5-toothcd. Corolla with 

 the tube short; the 4 upper lobes of the limb nearly equal, oblong and 

 declined, or vory short and rather erect ; the lowest lobe largest, oblong, 

 or rounded, mostly concave, Stamens exserted from the cleft between 

 the upper lobes of the corolla ; cells of the anthers confluent. Akenes 

 rugose. 



1. T. caxadexsk, L. Leaves ovate-lanceolate, serrate, hoary-pubes- 

 cent beneath, petiolate ; verticils crowded in a simple terminal spike ; 

 bracts linear-lanceolate ; calyx campanulatc, declined, upper teeth 

 broader. Beck, Bot. p. 274.

Canadian Teuchium. Vulgo — Wood Sage. Germander. 



Root perennial. Stem 1 to 2 or 3 feet high, simple, or sparingly branched, square, 

 with the sides concave, striatc-grooved, and the angles rounded, clothed with a 

 retrorse cinereous pubescence, often rather villose. Leaves 3 to 5 inches long, 

 and i to 2 inches wide, acute, or subacuminate, mostly obtuse or rounded at base, 

 and often a little unequal, green and sparingly pilose above, subvillose and can- 

 cscent beneath ; petioles 1 fourth to 3 fourths of an inch long, retrorsely pubescent. 

 Verticils 4 to 6-flowcred, mostly crowded, sometimes a little distant, in a simple 

 terminal sub-canescent or greenish-grey spike 2 to 5 or 6 inches In length (often 

 an opposite pair from the first axils beneath) ; flowers on short pedicels, with nar- 

 row lanceolate acuminate bracts at base about as long as the calyx. Calyx cam- 

 panulas, finally somewhat ventricose or gibbous, pubescent; the 2 lower teeth 

 lanceolate, the 3 upper ones ovate, broader and rather shorter. Corolla pale pur- 

 ple, minutely pubescent; the limb declined, with a fissure on the upper side, the 

 upper or lateral lobes erect, acute, the middle or lowest lobe oblong, or elllptic- 

 obovate, concave. Stamens ascending, exserted from the base of the fissure in the 

 corolla. Style longer than the stamens, curved, equally bifid at apex. Akenes 

 triquetrous-obevoid, rounded externally, reticulately rugose, greyish brown. 



Hob. Fence-rows, and low shaded grounds : frequent. Fl. July. FY. Aug— Sept. 



O65. This is usually about 12 or 15 inches high ; but is frequently found of a 

 larger growth, in the rich low grounds along the Brandy wine. I am satisfied, 

 however, that the T. xirginicum, of Authors, is identical with our plant,— and not 

 even a constant variety. One other species has been found in the U. States, on 

 the Rocky Mountains. 



Order 2. Aiigiospermia. 



A. Flowers usually Diandrous, by abortion. 



293. CATALPA, Juss. Nutt. Gen. 16. 

 [A name said to have been derived from our Southern Indians] 



Calyx 2-partcd. Corolla campanulatc ; limb unequally 5-lobed ; tube 

 ventricose. Stamens 2 fertile, and 2 to 3 abortive (rarely didynam- 

 ©us). Capsule long, cylindric, pod-like, 2-celled, 2-valved. Seeds 

 flat, membranaceously margined, and tufted at the ends.
