NEW CALIFORNIAN UREDINES. 249 
about half the length of the spores. Amongst the bicellular 
spores occur unicellular ones (mesospores). The teleutos- 
pores are enveloped by dark chestnut-brown paraphyses. 
On the leaves and stalks of Alliwm serratum. Near Anti- 
och, Cal., May, 1893, leg. Blasdale-—The uredosporic stage 
seems to develop only to a small extent. 
Puccinia procera, D. & H. Uredosori amphigenous; 
principally epiphyllous, oblong or linear, enveloped by the 
ruptured epidermis, ochraceous. Uredospores ovoid to spher- 
ical, finely echinulate, brownish, 32—45x#0—38u. Teleutosori 
hypophyllous, linear, disposed into parallel lines, covered by 
the unbroken epidermis, blackish, surrounded by a dense row 
of brown paraphyses. Teleutospores very different in form 
and size, oblong to linear, slightly constriced at septum, 
usually narrowed below, lower cell often stalk-like elongated, 
vertex mostly truncate and little thickened, smooth, clear 
brown, 45—100 x 18—23 yw. Pedicels short, brownish. 
On Elymus condensatus. Pasadena, Cal., Aug., 1893, leg. 
McClatchie—From Puccinia Rubigo-vera (DC.), Wint., 
which is said to occur on Elymus condensatus; P. procera 
differs by the dimensions of the teleutospores as well as of 
the uredospores. 
Puceinia Cryptanthes, D. & H. Sori scattered on the 
stems and the lower side of the leaves, oblong, minute, (0, 1 
—3 mm.), sometimes confluent. Uredospores broadly oval 
or globose, 24—28 x 20—24 y, rich brown echinulate. Tel- 
eutospore layers black, pulvinate. Spores irregular, mostly 
oblong, commonly rounded at the base, upper cell pointed or 
truncate, often obliquely, sometimes rounded, central con- 
striction little, apical thickening 5—10 y, smooth, brown, 34— 
50 x 19—30 w. Pedicels not firm, surpassing somewhat the 
length of the spores. Single-celled teleutospores rather 
numerous.
