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 cercocarpoid.es 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 18 13. 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 1 81 7. The first publication of Purshia Sprengel was neither 

 in his Systema (1825), nor in Steudel's Nomenclator, but in 



* Pittonia 2: 298. 1892.
