elliptical, entire, nearly smooth above, slightly hirsute below with scattered hairs, 
mucronate, short petioluled, texture firm, bearing a few, well-formed, amphi- 
genous teleutosori. The specimen was compared, under the guidance of Dr. 
J. N. Rose, with specimens in the phanerogamic herbarium of the U. S. National 
Museum, but could not be matched. 
The collection by Mr. Hotway is furthermore noteworthy in possessing 
aecidia, not heretofore known, which are rather pale and inconspicuous. ey 
may be described as follows: Aecidia hypophyllous, or somewhat amphigenous, 
crowded in small groups, pale yellow, without peridium, but sparingly encircled 
by incurved paraphyses; aecidiospores catenulate, globoid or globose-oblong, 
13-17 by 15-19, wall very pale yellow, thin, 1, finely and closely verrucose, 
paraphyses small, cylindrical, 5-7 by 24—30#, more or less contorted, wall usually 
thick, sometimes nearly obliterating the lumen, smooth, colorless: spermogonia 
epiphyllous, few in groups opposite the aecidia, brownish-yellow, punctiform, 
inconspicuous, subcuticular, conical, small, 60-80u broad and half as high, ostiolar 
filaments 20-24» long, free. 
CALLIOSPORA, nov. gen.—Teleutosori arising from beneath 
the epidermis, soon naked; teleutospores 2-celled by transverse 
partition, wall colored, with an external layer which swells in water, 
germ pores 2 in each cell, lateral. Aecidium and uredo wanting. 
Spermogonia arising from beneath the cuticle, conical. 
15. Calliospora Holwayi, n. sp.—Spermogonia epiphyllous, numer- 
ous over areas 2-7™™ across, punctiform, golden yellow, becoming 
brown, subcuticular, conical, 80-125 broad: teleutosori epiphyllous, 
scattered, sometimes confluent, small, round, blackish-brown; teleuto- 
spores elliptical, 26-34 by 40-514, rounded at both ends, slightly 
or not constricted at the septum, inner wall chocolate-brown, thick, 
3-4#, pores two in each cell, outer wall colorless, 2-3 thick in water, 
smooth; pedicel colorless, as long as the spore, swelling in water to 
the diameter of the spore and bursting—On Eysenhardtia amor- 
phoides HBK., Guadalajara, Sept. 28, 1903, no. 5059 (type), Sept- 
29, 1903, no. 5068; Oaxaca, Oct. 25, 1899, no. 3737: E. orthocar pa 
Wats., Etla, State of Oaxaca, Nov. 13, 1903, nos. 5404 and 5495. 
This species resembles Uropyxis Eysenhardtiae (D. & H.) Magn., but differs 
not only in the absence of the uredo,but in the position of the sori, the measure- 
ments of the teleutospores, and their smooth, colorless, outer wall. The collec- 
tions have been examined by Dr. J. N. Rosr, who says that the species of . 
Eysenhardtia have not been sufficiently studied, and some doubt must attach 
to the determination of the several numbers.
