our lowest tier of States and throughout Mexico this sp. seems 
generally to take the place of V. flexilis. 
65. NV. Wrightit, A. Br. Several spec., C. Wright's Cuban 
coll. 3716. Two forms of this, both in the Herb., and both 
under the same number; the one chosen by Braun as the type, 
’ dense and bushy, leaves about 1% mm. wide, and marginal teeth 
stout, many-celled at base; and about one half as long as the 
breadth of the leaf; the other called by Braun var. /axa, which 
has a lax, open form, with broader leaves, and often rather smaller 
teeth. a 
66. JV. arguta, H. B. K. Two spec. of Wright’s Cuban coll. 
3715 under this name, not the type, as one of them is marked, but 
NV. arguta. var. conferta, A. Br. (Seeman’s Jour. of Bot. ii, 
274) afterwards changed by Braun, in a paper read before the 
Berlin Nat. Hist. Soc., June 16, 1868 to WV. conferta, Braun. 
67. NV. Indica, Cham. For. sp. (JV. minor, var. Indica 
_ A. Br.; Caulinia Indica, Willd.) 
There is a spec. of this in the Herb. without locality or name 
of collector, but as it is mounted on a sheet with a spec. of JV. 
graminea, Del., from the East Indies, I suppose we may assume 
that it came from India. There are several forms both in Herb. 
Torrey and Herb. Gray that are labelled V. /ndica, but this is the 
only one which I feel sure is that species, and this unfortunately 
is a mere fruitless fragment. 
Var. gracillima, A. Br. (See Gray’s Man., fifth Ed. Supp.) 
Spec. from Albany, coll. C. H. Peck, are in the Herb. under the 
name of “ VV. minor, var. tenuissima, A. Br.,” with which -it has 
been sometimes confounded; and also spec. from N. J. It is not 
an uncommon form in our country... 
68. NV. marina, L., (NV. major, All.) Spec. 8; four of 
them marked WV. monosperma, Willd., a syn.; one from Cuba,. 
Wright's coll. 3718, one from Central N. Y., and one from Utah. 
Var. gracilis, Morong. One spec., Florida, Curtiss coll., 
2705. 
69. LV. muricata, Del. One spec. from Egypt. This sp. is 
distinguished from WV. marina by having the internodes and leaf- 
blades densely crowded with large teeth, which are longer than 
the breadth of the leaf.
