North American Flora the senior author observed the peculiarity 
of appendaged pedicels described by Montagne, and thought the 
species might be a member of the newly erected genus Prospodium. 
An appeal was made to M. Hariot in March, 1909, for a fragment 
of the original Cuban collection, which was most kindly sent, and 
which confirmed the suggestion. Some months previous to this 
the Pflanzenfamilien of Engler & Prantl had been searched for 
some illustration which would give the kind of leaf or leaflet 
figured by Montagne, without much success, although similar 
hairs were illustrated under Bignoniaceae. In January, 1909, the 
herbarium of the N. Y. Bot. Garden was searched for a similar 
purpose, and again with no better success. Going from New 
York to Washington, the National Museum yielded two sheets, 
possibly two collections, from Cuba by Charles Wright, made in 
1865, locality not given, labelled Tecoma lepidota DC., which 
showed compound leaves with leaflets that quite well answered to 
the requirements in Montagne’s record. With this aid the assis- 
tance of Prof. F. S. Earle, a sometime student of the rusts, was 
sought. Prof. Earle was at that time stationed at Jovellanos, 
about 80 or 100 miles west of San Marcos, the type locality. A 
statement of the situation, with a drawing of the leaf as given by 
Montagne, was sent in February, 1909. A hasty visit to the 
locality made by Prof. Earle in April, 1909, yielded no results, but 
in September, 1910, he transmitted two leaflets from “а Catalpa- 
like shrub with 5-parted leaves," and the statement that "at last 
I am able to send you what I take to be your long desired rust 
from the type locality; I chanced to stop with friends at San 
Marcos today [Sept. 26] and found one shrub with a few infected 
leaves." This collection gave uredinia only, but there was little 
doubt about its being the Montagne species. The host was still 
unnamed. In only a few weeks, however, an ample collection 
with telia and uredinia was received from Dr. N. L. Britton, col- 
lected in another part of the island, which supplied details for 
both host and rust, and the long search for definite knowledge of 
this curious rust and its obscure host was successfully ended. The 
result shows that the rust is curious, as stated by Montagne, that 
it is worthy of being placed in a separate genus related to Puccinia, 
Phragmidium, and Uropyxis, as believed by M. Hariot. Е inally,
