was on these specimens of P. lanceifolia, at least in part, that Kunze 
based his P. Æfliottü.* It is so indicated on the label. His de- 
scription agrees, except to the pubescence of the calyx, which 
must have been taken from the specimens of P. Virginiana. The 
name P. viscosa spathulacfolia has therefore to give away to P. 
Elliott, which is the older. Kunze thinks that it may be P. 
lanceolata Ell. It might possibly be so (I have not seen Elliott's 
specimens); but from the original description, and according to 
Dr. Gray, who had seen Elliott’s herbarium, this is a form of P. 
viscosa. 
Gray included in his P. viscosa spathulefolia,t also narrow-leaved 
forms of P. viscosa L. They are, so far as I can judge, what 
Nees and Dunal regarded as P. Pennsylvanica L. but this is, as 
stated before, only a small-leaved form of P. viscosa proper. The 
only available name is P. maritima Curtis. In the original de- 
scription, Curtis gives only one synonym, viz.: P, pubescens Engel. 
& Gray, PI. Lindh. and Lindheimer's specimens belong to this va- 
riety of P. viscosa. It will be known as P. viscosa maritima (Curtis). 
In 1874, Dr. Gray published his revision of the genus in the 
Proc. American Academy. Here three species and several va- 
rieties are described. The species are P. Wrightit, P. hedreacfolia 
and P. Fendleri. A few remarks on P. Wrightiü were made under 
P. lobata. P. hederaefohat and P. Fendleri are also good species 
The name of the former has been changed in the * New Check 
List" to P. digitalifolia (Torr.) Britton.$ The change, however, 
was unwarranted. It is true that it is the same as P. Alkekengi? 
var. digitalifolia Torr.|| but this was simply a wrong identifica- 
tion. Dr. Torrey believed that it was P. Alkekengi digitalifolia 
Dunal* Dr. Gray also held that the identification was erroneous 
as he gives asa synonym under P. hederacfolia, P. Alkekengt ?
