whether or no these are really distinct. At the same time cultures 
should be made with the spores of Puccinia tanaceti , DO., # to which they 
seem to be too closely related, to see again whether they are distinct 
from that species, for, af;er a careful study of a large and varied sup¬ 
ply of material and the accurate sketching of spores of each form, their 
validity is left much in doubt. Properly conducted cultures alone can 
positively decide the question. 
Puccinia Ellisiana, Thiim., in Bulletin of the Torrey Botanical 
Club, Yol. YI, p. 215, is now regarded by Mr. Ellis, Professor Earlow, 
and others to be the same as Puccinia andropogonis , Schweinitz, which 
has the right of priority. 
Puccinia Windsorle, Schw., var Australis, n. var. ( Puccinia 
Dochmia B. and C ., North Pacific Expl. Exped., No. 131, and Puccinia 
Palmeri , Scribner in herb.) On grass leaves, apparently Muhlenbergia , 
Nicaragua, Central America 5 C. Wright coll. No. 131, N. P. Expedition ; 
also on Muhlenbergia sp., Mexico; collected by Dr. Ed. Palmer, 1886. 
Hypogenous or sparingly amphigenous. Sori small, rather more pul- 
vinate than in the species, owing to the long spore pedicels, irregularly 
disposed, linear or oblong, more or less confluent, but rarely so in 
straight lines, the ruptured epidermis scarcely or not at all evident. 
Uredospores subglobose, obovate to oblong-ovate, brown, tegument 
somewhat thickened; epispore more or less distinctly echinulate, 16- 
25 by 20-26 ; teleutospores obovate, broadly elliptical to subglobose, 
the two last forms predominating; from pale to deep chestnut brown, 
usually darkest at the thickened vertex; little or not at all constricted 
at the septum, obtusely rounded or occasionally bluntly apiculate, 16- 
30 by 23-36 //; pedicel pale brown to subhyaline, 75-125 p long, by 
3 to 6 p thick at the base of the spore. Differs from the species in the 
very marked preponderance of the subglobose form of teleutospores 
and in the very long slender pedicels. A form almost the same as this 
occurs in the District of Columbia and in Florida. This form again is 
linked to the various forms of the species as they occur in different 
northern States. The description of the species itself should be a little 
more modified in order to embrace the usual, but not the glaring varia¬ 
tions. It is also to be noted that in the variety as well as in the species 
the spores are often more or less obliquely to vertiseptate and the ped¬ 
icels often to all appearances come from the side instead of from the 
base of the teleutospore. 
In Saccardo’s Sylloge, Yol. YII p. 770, are given brief descriptions 
of Triphragmium clavellosum, Berk., and Triphragmium Thwaitesii , B. 
& Br. The former occurs in America on Aralia nudicaulis , and is said 
(1. c.) to occur also in Ceylon on Paratropa terebinthinacea , Hedera and 
Amygdalew species. The latter is given for Ceylon as occurring on 
Hedera Vahlii , and the question is asked whether it is not the same as 
*A careful study should also be made of Puccinia tanaceti DC. var. ActineUcc Web¬ 
ber on Actinella acaulis. If this is a good variety, then perhaps some others now in¬ 
cluded in the species, should be regarded in the same light. Anders.
