This very distinct brachy-form was originally described from Porto Rico 
and St. Croix on V. albicaulis (l.c.) and on V. longifolia from Porto Rico. The 
above collections, excepting the last, were obtained from an examination of 
phanerogamic specimens in the herbarium of the New York Botanical Garden 
and, besides adding a new host for the species, extends the range to include 
Jamaica, Antigua, and Guatemala. 
8. Puccinia fraterna, sp. nov. 
O. Pycnia epiphyllous, few, gregarious, noticeable, subepidermal, 
blackish, globose, 110-120 p in diameter, ostiolar filaments not 
protruding. 
I. Aecia hypophyllous, few, crowded in small groups, opposite 
the pycnia, bullate, o. 2—o.5 mm. across; peridium short cylindrical, 
white, lacerate; peridial cells rectangular, abutted or slightly 
overlapping, 10-12 by 26-35 yw, wall colorless, outer wall smooth, 
1.5m thick, inner very closely verrucose, 4 u thick; aeciospores 
globoid or broadly ellipsoid, 18-23 by 23-32; wall colorless, 
I-1.5 w thick, closely and finely verrucose. 
II. Uredinia hypophyllous, few, scattered, small, 0.2-0.5 mm.

he specimens on which this species is based were obtained from phanero- 
gamic specimens in the herbarium of the New York Botanical Garden. The 
first collection mentioned bears all stages of the rust; the other, found on the 
type specimen of the host species, bears pycnia and aecia only. The material
