CALYPTOSPORA J. Kiilm. 



Eetercecious. Teloutospoivs intracellular, occupying the 

 swollen epidermal cells all round the stem of the host for a 

 considerable distance, otherwise as in Pucciniastrum. No 

 uredo. . lv-idi.-i cylindrical, with a thin peridium; aecidiospores 

 verrucose, without germ-pores, and with no smooth spot.

JEcidiospores. iEcidia hypophyl- 

 lous, arranged in two long rows 

 parallel to the mid-rib, cylindrical, 

 white, with torn or slit margin ; 

 spores ellipsoid, uniformly verrucose, 

 orange-red, 21 — 30 x 14 — 18 /n. 



Teleutospores. Caulicolous (the 

 fusiform attacked part of the stem 

 being swollen and at first clear- 

 pink, passing into brown), developed 

 in the epidermal cells, densely 

 crowded, prismatic, mostly divided 

 by crossed longitudinal walls into 

 four cells, up to 42 /u. high ; epispore 

 yellowish-brown, smooth, thickened (up to 3 /a) at the summit, 

 with a germ-pore at the upper and inner corner of each cell.
