CORRECTIONS IN NOMENCLATURE. 207 
As given by Dr. Gray in the Synoptical Flora, the genus 
Keerlia stands for an altogether different group of plants 
from those to which De Candolle assigned that collective 
name; and I offer as a needed substitute for this second 
Keerlia the name 
BOURDONTA. 
Keerlia, A. Gray, Pl. PS anti i. 92 (1852) not of De 
Candolle, Prodr. v. 309 (1836). 
J. Bourdon, a Parisian botanist of some reputation in an 
earlier part of this century. Of this genus only two species 
are known. 
1. B. bellidifolia, (Gray & Engelm. Proc. Am. Acad. 
i. 47 (1846) sub Keerlia). 
2. B. effusa (Gray, Pl. Lindh. ii. 222 (1850) sub Keerlia. 
Lotus Davidsonii. LZ. sulphureus, Greene, Pitt. ii. 293 
(1892), not of Boissier, Diagn. Ser. I, ii. 35 (1843). This 
recently detected Californian Lotus may take the name of its 
discoverer, Dr. Anstruther Davidson, since the adjective name 
at first assigned it was long since applied to an oriental 
species. 
Lotus eriophorus. ZL. tomentosus (H. & A.), Greene, 
Pitt. ii. 150 (1890), not of Schrader, Neue Journ. 42 (1809). 
Butneria occidentalis. Calycanthus occidentalis, Hook. 
& Arn. Bot. Beech. 340 (1840). There seems no room for 
doubt that Duhamel’s Butneria is the oldest of the several 
names that were proposed for this genus between 1755 and 
1759, 
Astragalus convallarius. A. campestris, Gray, Pro 
Am. Acad, vi. 229 (1864), not of Linnsus (1753). Tahabits 
valleys among the Rocky Mountains. 
Astragalus elegantulus. A. pectinatus, Boiss. Diagn. 
Ser. I, ii, 54 (1843), not of Douglas in Hook. Fl. Bor-Am., 
(1833). A Syrian species, to which Boissier inadvertently 
gave a homonymous adjective name.
