HARPER: DISTRIBUTION OF PLANTS OF THE COASTAL PLAIN 601 
still farther north (36°), and Pursh and several subsequent authors 
have assigned it a place in the flora of the northern United States. 
ORONTIUM AQUATICUM L. 
Seen just east of Hamlet and Laurinburg, North Carolina, 
and Tom’s River, New Jersey. At the first- and last-named 
localities it was accompanied by Chamaecyparis. 
Ry? A INEXPANSA (Michx.) Vahl. 
Common along the railroad between New Bern and Norfolk, 
often with Senecio tomentosus and equally weed-like. In 1906 T 
saw it in similar places in Gates County, North Carolina, and in 
1908 at various places between Norfolk and Emporia, Virginia. 
This species has perhaps never been openly charged with ‘‘weedi- 
ness’’ before, though I have known for years that it is usually a 
weed in Georgia. More information about its natural habitats 
(if it has any) would be welcome. 
RYNCHOSPORA ALBA (L.) Vahl (or its var. macra Clarke?). 
Very few stations for this in the South are known, so it may 
be worth mentioning that I found it in a sand-hill bog near Hamlet, 
NG. 
DICHROMENA LATIFOLIA Baldw. 
Last seen at about the same place as Lilium Catesbaei (see 
above), which corresponds pretty closely with the northern limit 
assigned to it by Kearney. It was doubtfully reported from 
Virginia in the fifth edition of Gray’s Manual, 1867, and has been 
generally regarded as a member of the northern flora ever since. 
More evidence on this point is desirable. 
CAMPULOSUS AROMATICUS (Walt.) Trin. 
Noted twice in Chatham County, Georgia, once near Hamlet, 
and once between Elkton and Rosindale, North Carolina. I saw 
it oftener in 1906, from about Chadbourn to Burgaw, in the last- 
named state, but not in South Carolina on either trip. It has 
been credited to Virginia by Pursh and many of his successors, 
but Kearney found it only near New Bern. 
ARISTIDA STRICTA Michx. es 
After leaving Georgia I saw this very characteristic grass of 
dry pine-barrens (from which the ‘‘wire-grass country” of Georgia, 
Alabama, etc., takes its name) only between Hamlet and Ply-
