496 RYDBERG: NOTES ON ROSACEAE 
identical, but no other specimens. The species must be very 
local. 
FALLUGIA 
Three species have been proposed in this genus, viz. F. paradoxa 
(D. Don) Endl., F. acuminata Cockerell and F. micrantha Cock- 
erell. Besides, the first has had two additional specific names, viz. 
Geum cercocarpoides DC. and Fallugia mexicana Walp. It has 
been impossible for the writer to distinguish more than one 
species, for the lobing or not lobing of the sepals is very in- 
constant, the same individual having both lobed and unlobed 
sepals, and the size of the petals is so variable, that no line can 
be drawn between F. acuminata and F. micrantha. In the essen- 
tially staminate plant the petals are usually larger. 
KUNTZIA vs. PURSHIA 
Dr. Greene,* when adopting the name Kuntzia instead of 
Purshia, made the following remarks: ‘‘A well-known rosaceous 
type of Rocky Mountain and Californian shrub, at first referred 
to the South American genus Tigarea, was taken up by the elder 
De Candolle in 1818, as a new genus, under the name Purshia. 
Sprengel, who about a year earlier, had himself published a genus 
Purshia, soon after proposed Kuntzia for the name of the Candol- 
lean Purshia; and this will apparently be the proper name for 
the western genus now called Purshia, which latter name is more 
than once revertible; for Rafinesque had a Purshia in print as 
early as 1813. I find no record of any earlier Kuntzia than this 
of Sprengel, which most writers who have mentioned it, say was 
substituted for the Candollean Purshia in Sprengel’s Systema, 
1825; but I find it four years earlier than that, in the first edition 
of Steudel’s Nomenclator (1821).” 
There is more than one correction to be made in the above 
statement. Purshia DC. was not published in 1818. The 
publication is usually cited as Purshia DC., Trans. Linn. Soc. Bot. 
12:157. 1818. The title page of that volume bears the year 1818, 
but the first part of it, in which Purshia appears, was published 
in 1817. The first publication of Purshia Sprengel was neither 
in his Systema (1825), nor in Steudel’s Nomenclator, but in 
* Pittonia 2: 298. 1892.
