recognizing such genera as Atragene, Conoclinium, Diplopap- 
pus, Leptopoda, Quamoclit, Batatas and Pharbits. He has now 
adopted a more conservative view, uniting all the above mentioned 
genera and many others, with their nearest allies; in this, how- 
ever, he is by no means consistent, for we find Hepatica included 
in Anemone, while Actinomeris is distinguished from Verbesina and 
if Otophylla and Dasystoma are both to be separated from Ger- 
ardia, Monniera, in the same family, should most certainly be re- 
moved from /erpestis, and Sophronanthe from Gratiola. 
About a dozen new species and innumerable varieties are de- 
scribed in the course of the work, several of them being unpub- 
lished names of Dr. Engelmann and other writers. The author 
has adhered to a rigid rule of exclusion in connection with the 
numerous new forms proposed during the last few years by other 
students of southern botany, remarking in the preface, “Ina region 
so vast * * * * there still must remain much to reward the labors 
of future explorers, and many new species have been proposed by 
recent collectors as occurring within my limits. These, which are 
unknown to me, when duly confirmed, * * * * will have place 
in future issues.” 
As a future issue embracing any extended revision is a matter 
of some uncertainty, it is to be deplored that Dr. Chapman did 
not make some effort to obtain material for examination at least 
in those genera in which he himself contemplated the establish- 
ment of new species. The omission of these well-marked forms — 
is less of an injustice to the botanists who have devoted time and 
careful study to the plants than it is to the field student who con- 
stantly discovers specimens which he cannot match with any of 
those described. It would be difficult for the chance collector of 
Clematis Addisoni to reconcile it with the diagnosis of C. Viorna, 
or Nolina Brittoniana with that of N. Georgiana; and yet there is : 
no other recourse for one who is dependent upon this flora alone. 
We are glad to note, however, that many excellent species of 3 
Buckley, Curtis and Shuttleworth, long suppressed by other a 
writers, have been properly reinstated by Dr. Chapman. The 
chief annoyance to botanists resultant from the omission of re- 3 
cently described species will be the addition to an already over- 
burdened synonymy which some of the wy numerous new varie- ; 
ties must make.
