Uromyces Limonii (DC.) Lev. 
I. On Limonium limhatum Small: Roswell, June, 1899, J. D. 
Tinsley; south of Tularosa [Cockerell). In the North America'n 
Flora this is not reported from the region between California and 
Mississippi. 
Uromyces IMedicaginis Pass. 
On leaves of Medicago sativa L. : Chamberino, Oct. 16, 1907, 
/. H. Bruce. The species should be found in New Mexico on 
Medicago lupulina, since it occurs elsewhere on that host. 
Uromyces mysticus Arthur 
On leaves of Hordeum jubatum L. : Farmington, July 22, 1911, 
Standley 7172 (II); Shiprock, Aug. 12, 1911, Standley 7884. 
Reported in the North American Flora only from Colorado and 
Utah. 
Uromyces occidentalis Dietel 
On leaves of Lupinus ammophilus Greene: Duke, Aug. 20, 
1911, Standley 82^4; a new host. On leaves of Lupinus Kingii 
S. Wats.: G O S Ranch, 1911, J. M. Holzinger. 
Uromyces plumbarius Peck 
On all chlorophyll-bearing parts of Gaura induta Woot. & 
Standi. : Pecos, Aug. 22, 1908, Standley 5176; Duke, Aug. 19, 
1911, Standley 8102; Farmington, July 22, 1911, Standley 7173. 
This species is reported from Colorado upon Gaura glabra Lehm., 
but the host is probably rather Gaura induta. Uromyces plum- 
barius occurs in other states upon Gaura coccinea, G. parvifiora, 
G. villosa, Pachylophus hirsutus, and P. inacroglottis, and should 
be sought in New Mexico upon the same hosts. It may be ex- 
pected to occur also upon some of our Oenotheras, for it is found 
elsewhere on O. biennis. 
Uromyces proeminens (DC.) Pass. 
On leaves of Chamaesyce serpyllifolia (Pers.) Small: Farm- 
ington, July 22, 1911, Standley 7160; Cedar Hill, Aug. 16, 1911,
