teleutospores does not accord with the present species. It is there 

 stated: "III. Soris pallidis, compactis, hemisphericis. Teleutosporis 

 lanceolatis, pallidis, lajvibus (.05 X -02 mm.). Episporia supra in- 

 crassato." I add a description of the Florida fungus. 



Ukojiyces Martixii Farlow. Sori round, naked, scattered ir- 

 regularly over both sides of the leaves. Uredo spores pale brown, 

 oval, and occasionally triangular in outline, echinulate, 18-22/a in 

 diam., average HOix. Teleutospores dark brown, short- stalked, globose 

 or broadly elliptic, 26-3o/x by 22-26/i,, cell wall thick, smooth or 

 slightly roughened, apex with a prominent hyaline, broadly couical 

 papilla. 



On Melanthera hastata. Florida. Dr. Martin. 



The species, it will be seen, is characterized by its broad, globose, 

 thick-walled teleutospores, with very marked hyaline papilla at the 

 apex. The uredo spores not unfrequently are more or less triangu- 

 lar in outline, but whether this is the result of drying I cannot 

 say. At any rate, potash fails to restore the original form, if it were 

 oval. A comparison with the description of U. Melantherce shows 

 that the description of the uredo spores corresponds more closely to 

 the teleutospores of our plant than to the uredo spores, and were it 

 not that the expression "teleutosporis lanceolatis" occurs, one would 

 say that our fungus and that from Natal were the same, and that 

 there was an inversion in the description of the uredo and teleuto- 

 spores. 



No. 1072. Uromyces LiUacearum Unger. In Rabenhorst's Kryp- 

 togamen Flora this species is placed by Winter in the subgenus 

 Uromycopsis, in which aecidia and teleutospores are known, but the 

 uredo is wanting. I found the uredo and teleutospores of the species 

 growing together at Shelburne, N. II. The uredo sori are small and 

 long covered by the epidermis, and the spores are oval, bright yellow, 

 and measure 23-26/x in diameter, the surface being slightly echinulate. 

 In this connection it may be remarked that, in his Twenty-seventh 

 Report, Peck mentions the occurrence of a iiredo on Lilium Ganadense, 

 which he refers to U. Smilacis Schw. The present species is also 

 found in Massachusetts, where the oscidium accompanies or immedi- 

 ately precedes the Uromyces. 



No. 1073. Calyptospora Gceppertiana Kuhn. Although known 

 for some time in the Western States on Vaccinium ovalifoUum, the 

 species has not frequently been found in the East. I have already 

 called attention to its occurrence on Vaccinium corymhosnm near 

 Boston, where it is rare, but it is common in the White Mountain
