Supplement to Dr. Chapman s Southern Flora, University Press. 
Cambridge: John Wilson & Son. 1883. 
Since the publication of Dr. Chapman's Southern Flora, in i860, a 
large number of species has been discovered by various collectors 
withm the region it embraces, and botanists have long felt the need 
of a work describing these additions. This Supplement is intended 
to mclude these, as well as certain species which were omitted in 
the Flora, and forms a most valuable contribution to North Ameri- 
can botany. It contains 96 pages, with index, is printed in the 
same form and type as the Flora, and is paged in continuation with 
the latter, making a total of 6g8 pages. Seventy-eight genera are 
added to the Flora, and about 450 species and varieties are de- 
scribed. Some of these, however, must count as corrections to the 
first edition. Scutia ferrea is Reynosia latifolia, Griseb., in the 
Supplement; Gallactia spiciforniis, var., is G, fiUformis, Benth.; 
'^cfioenolirion Michauxii is S, Elliottii, Feay ; Panicum sanguinale, 
var.^ is p^ serotinum^ Mx., and Andropogon tetrastachys, var., is 
raised to the rank of a species under the name of Andropogon 
arctatus. Chapman. 
The following are proposed as new species : Polygala ReynoldsiZ^ 
Chapm.; PeialostemonFeayi, Chapm.; Pinguicula Floridensis^ Chapm.; 
Euphorbia Garheri and deltoidea^ Engel., ined.: Croton Alabamensis, 
E.^ A. Smith, ined.; Tillandsia Houzeavi, Morren, ined.; Xyris 
and Andropogon 
setacea^ Chapm.; Pasp 
maritimus, Chapm. 
a r.^^^^^ genera and fifty-five species of grasses are described. 
L, (?V'* from the description, must be P. glaber, 
Pharus latifolius 
■"^th, (P, latifolius, Trin., non L.) ; '' Sporobolus Dotningensis, Sw.," 
was distributed in Mr. Curtiss' sets as S, purpurascens, Hamilt. 
Although synonyms are very generally cited, adding much to the 
value of the work, they are omitted in the case of Thurderia Arkan- 
^^na, Benth., a grass long known under the names Greenia, Nutt., 
a»d Sclerachne, Torr. '' Paspahim monostacliyum, Vasey, ined.," 
was referred by General Munro to P. rectum.^tts., *' spicislongiore." 
Paspalum obtusifolium, Raddi," No. 3,565 of A. H. Curtiss, is P. 
P^^itycaule, Poir. No. %ii of E. Hall's Texan collection is the same. 
A very satisfactory attempt is made to separate the various forms 
oj Panicum that have been lumped together under P, dichotomum by 
^J^- Gray and others, and the following are recognised as species :
