lines thick), pale brown. — Cultivated in the Botanic Garden, Cam- 

 bridge, from roots collected iu 1888 near Wilmington, N. C, by 

 Mr. VV. A. Manda. Resembling in some respects /. versicolor of the 

 Northern States, as it has been generally understood, which doubtless 

 also includes the /. Vlrginica of Liunajus as represented by the origi- 

 nal Gronoviau specimen preserved in the herbarium of the British 

 Museum. That species differs most notably in its erect glaucous and 

 often much sliorter leaves, and its very much smaller seeds in two 

 rows iu each cell. There are also less obvious differences in the col- 

 oring and shape of the smaller flowers. It varies to a considerable 

 degree, especially in size, but in its main characters it appears to be 

 constiint and well defined. 



SiSYRiNCHiUM ANGcsTiFOLiuM, Mill., and S. ANCEPS, Cav. Upon 

 comparison of plants of these species growing side by side near Cam- 

 bridge on the 1st of June, 1890, the differences in the inflorescence 

 were found to be constant. The glaucous hue was much more de- 

 cided iu the latter, while the flowers wei-e indistinguishable, except 

 that in S. anceps they were somewhat darker and the yellow spot at 

 the base of each petal broad and truncate or emarginate at the top, 

 but in S. anffiistifolium somewhat narrowed and irregularly rounded 

 above. This latter species was already nearly past bloom, with the 

 older capsules and seeds of full size ; the other was just coming into 

 bloom. 



Camassia Howellii. Bulb rather small, bearing few leaves 

 about a foot long by 2 to 5 lines broad : flowering stem and elongated 

 many-flowered raceme nearly 2 feet high ; pedicels spreading, be- 

 coming 9 to 12 lines long, at least twice longer than the linear bracts : 

 petals pale purple, ^ inch long, 3- (rarely 4- or 5-) nerved : capsule 

 broadly triangular-ovate, very obtuse, 3 lines long ; cells 2-3-seeded. 

 — At Grant's Pass, Oregon; Thomas Howell, 1889. P'lowering in 

 May ; flowers opening at about 2 p. m., remaining open till sunset. 

 Distinguished from other western species especially by the small 

 capsules on slender widely spreading pedicels. 



Sabal Mexicana, Mart. A palm which in the present imperfect 

 knowledge of the species cannot be distinguished from S. Mexicana 

 was collected by Berlandier (n. Sll , '■^ Corypha edidis") near Glata- 

 moras, and has more recently been found on the Texan side of the 

 Rio Grande near Brownsville by Dr. Gorgas and by Prof. C. S. 

 Sargent. This is the same also as 314 Ervendburg, collected on the 

 savannas near Tantoyuca in the Department of Vera Cruz. It is 

 said to be frequently 20 or 25 feet high, with a well defined trunk
