“ Caeoma (Uredo) interstitiale 11. sp. Folia, quae infestat 
hoc Caeoma, caeteris, liaud affectis, remanent multo minora et 
minus evoluta. Maculas in superiori foliorum pagina in planta 
sicca conspicere liequeo. Acervi, in pagina inferiore in nervorum 
mterstitiis positi, oblongi, lineares, confluentes, fere totum inter- 
stitium occupantes, prius parum elevati, convexiusculi, epidermide 
tecti, quae postea, rima longitudinali irregulariter rumpens, pul- 
verem, in siccatis luteum, liberum reddit ; epidermidis vero frag- 
menta ad latera undulatim resistunt. Sporidia irregularia, rotund- 
ata, efToeta pellucida, saepius lineis obscuris varieintricatisimpleta,
