26 PITTONIA. 
I have, in the interval, given such attention as I was able 
to give, to history of the genus in times subsequent to Lin- 
nius; and this line of research has proven no less interest- 
ing than was that of the field study of the plants in question. 
Some results of this bibliographie work I desire here to place 
upon record, for the use of any who may in the future take 
up and carry forward to completion a classification of the 
CHAMJECRISTA species. 
The genus, proposed as such, and duly published under 
this name, is ante-Linnzean, as I said formerly; but its real 
founder is not Commelin (1697) but Breyne (1678). And 
since 1753, when Linnzus suppressed it, I find four differ- 
ent authors reinstating it anteriorly to my own paper of 
1897. And it so far seems to hold perfectly true, as I inti- 
mated in the earlier paper, that none of these earlier sup- 
porters of the genus studied the corolla to the extent of 
understanding it and making out its peculiarities. Besides 
Meench (1794 [misprinted 1694 in Pitt. iii, p. 241]), the 
other and later botanists maintaining the distinctness of 
these plants from Cassia are, Schrank (1805), who gives it a 
new name, Grimaldia ; Ernest Meyer (1825), who maintains 
the prior and rightful name, and Rafinesque (1838); this 
author also retaining the rightful name, but following his 
own whim of making the English X stand for a Greek Chi, 
the name with him reading Xamacrisia, which he neverthe- 
less must have pronounced Kamacrista. 
Again: all authors from Linnzus down to our time who 
have monographed the Cassias—Linnsus (1753 & 1762), 
Colladon (1816), De Candolle (1825), Vogel (1837) and Ben- 
tham (1871)—have admitted Chamzerista as a subgenus, and 
have placed it last in the series, as made up of plants the 
most remote of ail from the true type of Cassia. 
In so far as my examination of these authors has pro- 
ceeded, I observe that while with all of them the members of 
the Chamzcerista section are veritable Chameecristas, yet 
other excellent species of the same group are found to be
