SUPPLEMENTARY NOTES. 
By F. W. Anderson. 
The foregoing list was kindly sent to me by the Rev. F. D. Kelsey, 
with the request that I add any names and notes at my command. 
Having in 18S7 spent several months collecting in the vicinity of Helena 
in company with Mr. Kelsey, and collected in the same neighborhood 
again in 1888, it is with pleasure I add the following: 
Although the combined list is small, it extends the ranges and hosts 
of some species, besides giving a few new to science. 
iEciDiUM cleomis, Ell. &. Anderson. On Cleome integrifolia. Appearing chiefly on 
young plants, affecting the leaves and petioles, and occasionally the stems. 
iEciDiUM compositarum, Mart. Very abundant on Troximon glaucum, often destroy¬ 
ing leaves of feeble hosts. Same on Solidago rigida. 
iEcimuM lepidii, Tracy & Galloway. On Lepidium intermedium. A beautiful scar¬ 
let species, the broad, white marginal lobes contrasting strongly with the rich 
color below. Not very common. 
iEcimuM monoicum, Pk. On Sisymbrium linifolium. One of the earliest to appear. 
Changes structure of host leaves, causing them to become oval or roundish in 
outline and much thickened and brittle, margin strongly recurved. Preceded 
by the remarkably fragrant spermogonia which exude a sticky fluid with a 
perfume between that of the English Sweet Violet and Hedge Primrose. This 
fluid is very attractive to beetles, flies, bees, and ants. A destructive fungus 
having several known hosts and which may in time, perhaps, attack cultivated 
Crucifer on. 
iEciDiUM urtioe, Schum. On Urtica gracilis , was very abundant in Oro Fino Gulch, 
near Helena, in 1887. It damaged its host considerably. 
Piiragmidium potentillvE, (Pers.) Wint. On Potentilla Pennsylvanica and P. dissecta 
(mountain form). Common and very conspicuous. The rich reddish, orange- 
colored uredospores are frequently present with the large, black, velvety teleu- 
to-sori, forming a marked contrast. 
Puccinia arerrans, Pk. f On Sisymbrium linifolium. Succeeding JEcidium monoicum 
as a rule, but sometimes appearing on the same leaves while the latter is at its 
best. This is said to differ from the type. I have a typical specimen of this 
Puccinia on the first published host. I also have it varying more or less from 
the type form on several hosts in other genera from Colorado, Washington 
Territory, and Utah. No two are alike but all are evidently of one species. 
The form on Sisymbrium linifolium seems to tit in with the rest and if another 
species it is closely related to P. abtrrans. 
Puccinia caricis, (Schum.) Wint. On Carex Jamesii var. Nebraskensis , Carex Jili- 
folia, Carex Douglasii , Carex Pennsylvanica, Carex marcida and Carex utriculata. 
The other Carices of this locality do not seem to be affected by the parasite,
