124 PENNELL: STUDIES IN THE AGALINANAE 
D. macrophylla (Nutt.) Raf. (1837). Seymeria macrophylla Nutt. 
was in 1846 made the basis of a section Brachygyne Benth., 
which in 1903 was raised to a genus Brachygyne (Benth.) Small, 
identical with the older Dasistoma Raf. The genus is monotypic. 
In 1834 Nuttall described a new genus Conradia based upon 
a large and showy plant, specimens of which he had seen in the 
herbarium of the Philadelphia Academy of Natural Sciences. 
His name Conradia was antedated by Conradia Raf. (1825), and 
by Conradia Mart. (1829), so in 1835, in the account of the plants 
of Drummond’s collection, the name was changed to Macranthera. 
Though this series of articles in the Companion to the Botanical 
Magazine was mostly the work of the editor, Sir W. J. Hooker, 
Bentham is to be credited for this genus. In the original descrip- 
tion Le Conte’s and Bentham’s names were both cited after the 
genus, but in a later article during the same year Bentham tells 
us Macranthera was a manuscript name used by Dr. Torrey in 
communicating the plant to Dr. Lindley. Doubtless because 
the collector of the plant in Torrey’s herbarium (however described 
two years later as a second species) Le Conte was mentioned, 
so with Bentham’s explanation Torrey’s name may be con- 
nected with the plant in question. Conradia Nutt. was based 
upon C. fuschioides Nutt., the spelling of which was corrected 
to fuchsioides in the combination Macranthera fuchsioides (Nutt.) 
Benth. However, as this plant had been previously described by 
William Bartram in his Travels (1791) as Gerardia flammea, this 
species must become Macranthera flammea (Bartram) Pennell 
comb. nov. 
In 1835 Bentham reviewed this tribe, adding no new generic 
names, but systematizing and coérdinating the whole, and with 
another revision in 1846 giving the outline which has been mostly 
adopted since. f 
In 1837 Rafinesque undertook the special elaboration of this 
group in his New Flora of America, adding several new generic 
names, not giving us a very satisfactory or codrdinated treatment, 
yet showing nevertheless a surprising insight into the group. 
As I have already had to refer to several of his names, as he 
proposed a number of genera which must be adopted, and as since 
his time no new genera have been proposed which he had not 
already defined, it will be well to go carefully over his treatment.
