492 TRANS. OF THE ACAD. OP SCIENCE. 



Pag. 448. J. stygius also on the north shore of Lake Su- 

 perior, 0. B. Wheeler ; it seems rare everywhere, so that I 

 have not yet been able to obtain it in sufficient quantity for 

 the Herb. norm. 



J. Vaseyi ; while I was deploring the destruction of Dr. 

 Vasey's original locality, Rev. Mr Holzer and Dr. Bigelow 

 discovered this species in abundance in damp open woods on 

 both sides of the river near Detroit, growing together with 

 J. Greenii. Dr. Bigelow's fine specimens are distributed in 

 Herb. norm. 17. Many of them are "l\ teet high. 



Pag. 449. J. Greenii; Dr. Bigelow's Detroit specimens, 

 Hb. n. 19, are 2-2£ feet high, taller and stouter than those 

 found on the coast, Massachusetts, II Mann, Hb. n. 18, 

 Maine, E. Tuckerman. — Both species hold their own per- 

 fectly well, and can always be readily distinguished by the 

 characters given above ; J. Vaseyi is also a much more slen- 

 der plant and flowers earlier, maturing its fruit, near Detroit, 

 in the beginning of July, when the other is just in flower. 



Pag. 450. J. tenuis ; a form with long spathes, most spe- 

 cimens tall, is Hb. n. 20 from Pennsylvania, Porter ; another, 

 even taller, with the flowers often one-sided, is 21, from Illi- 

 nois, Hall; 22 is the var. congestus, from California, Kellogg, 

 unfortunately in too few specimens; 23 is var. secundus, from 

 Pennsylyania, Porter. 



J. dichotomies has been found as far north as Delaware and 

 New Jersey, Leidy, Commons, Parker, Hb. n. 24, and others. 

 Mr. Ravenel sends from South Carolina a taller form, lib. n. 

 25, and a smaller, few-flowered one, 26. 



Pag. 451. J. Gerardi, Massachusetts, Mann, Hb. n. 27. 



J. bufonnis, Hb. n. '2.8, is an erect form from the coast re- 

 gion of California, JSolander. — Prof. E. Hilgard found on the 

 sandy beach of Ship Island in the Mississippi Sound the var. 

 fasciexdiflorus with perfectly smooth seeds; specimens of 

 the same sent by Lindheimer from Galveston show extremely 

 slight marks. 



26. b. J. triformis, n. sp. : caule annuo brevissimo foli- 

 oso ramuloso ; pedunculis capillaribus scapiformibus numero- 

 sis (|-4 pollicaribus) folia brevia fiiiformia supra canaliculata 

 apicem versus plana longe excedentibus ; floribus paucis capi- 

 tellat.is vel singulis; sepalis lanceolato-subulatis fflquilongis 

 capsulam ovatam obtusam mucronatam 2-3 locularem fere 

 aequantibus; seminibus ovatis obtusis breviter apiculatis te- 

 nuiter pauci-costatis et transverse lineolatis. 



Var. a. stylosus : planta major (2-4-pollicaris) ; capitulis 

 3-5-floiis ; sepalis stamina et capsulam longius mucronatam 

 paulo excedentibus; antheris longe-linearibus filamento plus 

 quam duplo longioribus ; stylo ovario ovato pluries longiore 

 exserto, sii<fmatibus elongatis. 



Var. 8. orachystylus : planta minor (1-2-pollicaris) ; flori-
