Vittaria lineata, take possession of the trunks of the young palmet- 
tos, thrusting their roots down between the sheaths and the trunk. 
A palmetto thus adorned is certainly a beautiful object. 
The blue palmetto, Sadal Adansonit, also occurs in the “ ham- 
mocks.” It never attains a height of more than three or four feet. 
Among the other plants restricted to the hammock lands are: Zra- 
descantia pilosa, Coreopsis Leavenworth, Solidago Leavenworthii, 
Flelenium nudiflorum, Teucrium Nashii, Berchemia scandens, Cardio- 
Spermum microcarpum, Eryngium Baldwinii, Ulmus Floridana and 
U. alata, Celtis Mississippiensis and Capsicum baccatum. 
Owing to this exceeding variation in the physical conditions 
of the country explored, I was enabled to secure a large number of 
species, some 800, several of them being new to science and 
others additions to the flora of the United States. The range of sev- 
eral plants was extended much further south. I also secured a 
number of rare things hitherto poorly represented in herbaria. 
The following are some of those of peculiar interest : 
1153, 1180. CASTALIA RENIFORMIS (Walt). [Mymphaea rentformis 
Walt.) 
This was found growing commonly in Lake Ella. There 
seem to be two forms of it, one growing along the shore, the 
other in water 10 to 20 feet deep. The two merged into each 
other, and a careful comparison showed them to be the same. 
The rootstocks of the shore form were secured and there was no 
indication of any tubers. The leaves varied from 6 to 8 inches in 
diameter in the shore form, to nearly 2 feet in the one growing in 
deep water. The edges of the latter were distinctly turned up, 
much as in the Victoria Amazonica and occurred in large masses, 
making it difficult to propel a boat through them. The flowers 
were long and entirely without odor, with the exception of a faint 
Suggestion of that given off by apples. 
815. Eler1anrHemum Nasui Britton, n. sp. 
Diffusely branched from a thick woody, horizontal root, the 
branches decumbent or ascending, slender, terete, densely stellate- 
tomentose even when old, leafy, 2-4 dm. long. Leaves oblong or 
linear-oblong, densely stellate-canescent on both sides, ste at 
both ends or the lower obtuse at the apex, I1.5-3 cm. long, 
3-6 mm. wide, short-petioled, the margins somewhat revolute ; 
flowers all alike in terminal leafy-bracted thyrsi; pedicels 2-5 mm.
