als characteristisch fur die Art die: Hyphae primaria simplex 
und den habitus cupressiformi hervor.” I will venture to include 
Maire’s name in the list of synonyms, since if our species is 
that described by this author, it must also be a synonym of 
Corda’s species. 
I may also add that Mjons. le Prof. C. A. J. A. Oudemans,, 
of Brussels, took our species for a republication of his, but in 
a subsequent letter notified me that he regarded ours (and 
his) as Corda’s species, a judgment approved, so he stated, by 
the eminent mycologist Mons. P. A. Saccardo. 
I am indebted to Professor Morgan and others for most of 
the items in the following which is perhaps the complete 
synonomy to the present time: 
1. Botryosporium pulchrum Corda, Prachtflora, 1839. 
2. Botryosporium elegans Corda, Anleitung. 1842. 
3. Cephalosporium elegans Bonorden, Handb. 1851. 
4. Phymatotrichum pyramidale Bonorden, Handb. 1851. 
5. Botryosporium pyramidale Costantin, Mus. 1888. 
6. Botrytis longibrachiata Oudemans, Microm. 1890. 
7. Botrytis (Polyactis) doryphora Pound & Clements, Bot. 
Surv. Nebr. III. Rep. 1893. 1894. [Phymatotrichum dory¬ 
phora Pound & Clements in herb.]

PUCCINIA LATERIPES B. & RAV. AN AUT-EU-PUCCINIA., 
W. A. KELLERMAN. 
It has been assumed hitherto that the pycnidial and aecidial 
stages as well as the uredo and teleutospores, occurring on Ruel- 
lia strepens, were the polymorphic forms of one and the same 
species of Puccinia. Cultures were instituted to determine the 
correctness of this view. 
In late winter at an opportune time roots of Ruellia strepens 
were removed to the greenhouse. Old stems and leaves infected 
with the Rust were at the same time afforded like opportunity to 
absorb heat which presumably would render the spores viable 
when wanted for inoculations. The experiments were carried 
on as related below. 
After the plants had resumed their vegetative activity and 
shoots a few inches long had developed (March 5th), some soil 
together with the partially decayed leaves adjacent to the stems, 
exposed in the natural habitat all winter, was placed around and
