A uteupuccinia. 161 
Puccinia vinex. (D. C.) 
Spermogonia—Scattered over the whole leaf-surface and stems, 
yellow, sweet-scented. 
A cidiospores—Sori pulvinate, not cup-shaped, but discoidal, solid, 
2-3mm. in diameter, dark brown, with a greyish lustre. Spores 
globose, finely echinulate, colourless, ro-12u in diameter. 
Uredospores—Primary : Sori irregular, elongate, crowded, soon 
naked and often confluent, brown, occurring with the spermo- 
gonia and ecidiospores. Secondary: Sori on roundish brown 
spots, brown, long covered by the epidermis. Spores sub- 
globose, or obovate, brown, echinulate, 20-38 x 18-25, 
Teleutospores—Sori small, on discoloured spots, roundish, scattered, 
surrounded by the ruptured epidermis, blackish. Spores 
elliptical or oval, slightly constricted, lower cell sometimes 
attenuated, sometimes rounded, upper cell thickened above, 
often surmounted with a pale papilla, chestnut-brown, verru- 
cose, 38-56 X 17-28. Pedicels rather long, deciduous.

BIoLoGY.—The life-history of this species is peculiar. The mycelium 
of the ecidiospores is perennial, and causes the affected plant to pro- 
duce shorter and thickerleaves. The zcidia are not cups, but convex 
or flat sori, more resembling a Coryneum than an ecidium. The
