gus than true roots, and the conclusion reached was, that at that period of 

 its life, at least, the plant drew its nourishment from the decaying vegeta- 

 ble matter among which it grew. Whether during a previous period the 

 roots were connected with those of trees could not be ascertained, but all 

 appearances were against such connection. (See Vick's Monthly Maga- 

 zine, vol. v., p. 330-332.) 



BIGNONIACE^. 



430a. Catalpa speciosa, Engelm. — First brought into notice by the 

 late Dr. J. A. Warder, and by him considered a valuable tree for building 

 and other purposes. The following is the description from Botanical Ga- 

 zette, vol. v., p. 1 : 



"A middle-sized tree, with grayish brown, much cracked or furrowed, 

 at last slightly flaky bark, and light yellowish gray wood ; leaves large, 

 truncated or more or less cordate at base, slightly acuminate, soft, downy 

 on the under side, inodorous; flowers in large and loose panicles; tube of 

 the corolla conical, longer than wide, its lower part scarcely protracted ; 

 upper lip before its expansion longer than the other lobes and enveloping 

 them; lower lobe bi-lobed; inside of the corolla slightly marked at the 

 throat with red-brown lines, and with two yellow bands at the commissures 

 of the lowest with the lateral lobes ; stamens and style as long as the tube, 

 pod terete, strongly furrowed ; wings of the seed about as long as the seed 

 itself, rounded at the ends and split into a broad coma." 



LABIATES. 



471a. Trichostema dichotomum, L. — Found during 1883 on the Ohio 

 River bank. A very much branched herb, with small flowers, and similar 

 in habit of growth to Isanthus caeruletis, Michx. 



CONVOLVULACE^. 



533. Convolvulus arvensis, L. — Found by Mr. Spurlock and Mr. 

 Going. 



535a. Jacquemontia tamnifolia, Griseb. — A few specimens of this 

 species, native much further south, were found by Mr. C. B. Going at the 

 Stock Yards on the C. W. & B. R. B. The description is appended. The 

 plant can be considered as only a waif, and may or may not be found again. 



"Jacquemontia, Choisey. — A rather small genus, tropical or sub- 

 tropical, mostly with the aspect of Convolvulus. 



"J. tamnifolia, Griesb. — Erect or at length twining, fulvous-hirsute; 

 root annual; leaves cordate and ovate, long petioled, pinnately veiny;
