Not less important than the natural advantages of the Station in climate 
and vegetation is its accessibility, and the fact that it is located in an English- 
speaking country with a stable government and reliable sanitary control. For 
the past ten years it has been a station of the New York Botanical Garden, but 
it is now to be maintained under the auspices of the British Association for the 
Advancement of Science with the cooperation of the Jamaican government.—

Cultures of the Uredineae.—In the review covering the cultural work with 
the Uredineae for 1912,4 the following results of TREBOUx and of Lone should 
have been included. TreBouxs in two papers from Nowotscherkask, reports 
the following cultures. Teleutospores of Uromyces Festucae Syd. from Festuca 
ovina L. produced aecidia on Ranunculus illyricus L. (The reverse culture 
has previously been reported.)® Aecidiospores from Allium decipiens Fisch.., 
A. moschatum L., A. rotundum L., and A. sphaerocephalum L. produced uredo- 
spores and teleutospores (Puccinia permixta Syd.) on Diplachne serotina Lk. 
The reverse infection on 3 of these and 13 other species of Alliwm was success- 
ful also. Teleutospores of Puccinia stipina Tranzsch. from Stipa capillata L. 
infected 5 native species of Salvia and 15 others grown from seed, and also 
Origanum vulgare L., Lamium amplexicaule L., Glechoma hederacea L., Lal- 
lemantia iberica F. et M., Leonurus cardiaca L., and Stachys recta L. This rust 
shows very little selection among the Labiatae. Puccinia littoralis Rostr. 
from Juncus Gerardi Lois. produced aecidia on Cichorium Intybus L. (the reverse 
culture has been previously reported). Aecidiospores of Puccinia Polygoni- 
amphibii Pers. from Geranium collinum aici Infected renee amphibium 
L. but not P. lapathifoliumL. Th n Geranium 
collinum L., G. pratense L., G. divaricatum Ehbrh., G. columbinum L., and G. 
rotundifolium L. Aecidiospores of the autoecious form P. ambigua Alb. et 
Schw. on Galium aparine L. produced successive generations of aecidia when 
sown on that host. Aecidiospores of Puccinia Agropyri Ell. et Ev. from 
Clematis pseudo-lammula Schmalh. infected Agropyrum repens P.B. The 
uredospores from this culture infected Agropyrum cristatum Bess. and A. 
prostratum Eichw. Aecidiospores of Puccinia bromina Erikss. from Litho- 
spermum arvense L. infected Bromus tectorum L. and B. squarrosus L. Similarly 
_aecidiospores from Myosotis silvatica Hoftm, infected B. tectorum. The two 
aecidia belong to the same rust. Aec idiospores and uredospores of Uromyces 
Limonii (DC.) from Statice latifolia Sm. infected Statice Gmelini Willd. also. 
Aecidiospores of an unnamed species of Puccinia from Centaurea trichocephala
