72 CATALOGUE OF 



H. palustris, Linn. p. Au. 2/ 2 — 5 ft. River swamps. Undoubtedly 



synonymous with the preceding, as the position of the peduncle 



and the form of the leaf is not constant, even in the same specimen. 



H. trionum, Linn. Flower of an hour. y-w. and p. Ju. (?) 1 — 2 ft. 



Cultivated fields. Naturalized. 

 HiERACiUM ^rojio^ju, Linn. y. Ju. j^ 1 — 2 ft. Dry woods. 

 H. venosum, Linn. y. Ju. 2/ 1 — 2 ft. Dry woods. Having never 

 been able to find this plant with a glabrous or even smooth^^calyx, 

 and a uniformly leafless scape, which are considered as the dis- 

 tinguishing characteristics, I am more confirmed in the opinion, 

 published many years since, that it is a mere stemless variety of 

 the preceding extremely variable species.

 Hyssopus «e;?etoides, Linn. g-y. Sf g-p. Ju. 2/. 3 — 6 ft. Woods. 

 H. scrophularifoUus, Willd. p. Ju. ^l 3—5 ft. ^ With the last, 

 closely resembling it, and very probably a mere variety, as the form 

 of the leaf cannot be relied upon, neither can the length of the style 

 as this increases in length as the flower approaches maturity.
