later found in Hope Gardens, Jamaica, by Eug. Mayor, and 

 verified by him (Mem. Soc. Neuch. Sc. Nat. 5: 577. 1913). 

 Material representing this species of Uredo does not yet occur in 

 any American collection. Greatly to my surprise the two 

 West Indian collections detected by Mrs. Chase, one being from 

 Jamaica where Mayor made his collection, are wholly unlike 

 the species described by Sydow, and in fact appear to represent 

 one that is undescribed and very distinctive. We take pleasure 

 in naming this new species in honor of Mrs. Chase as a slight 

 recognition of her devotion to botanical investigations, her 

 eminent services to agrostology, and her disinterested assistance 

 freely given to workers in other lines of research. The species 

 appears to be most closely related to Puccinia polysora Underw., 

 on Tripsacum, which has larger urediniospores, however, with 

 five instead of four pores, and has not yet been found in the 

 West Indies. The description of Uredo Anthephorae given by 

 Sydow and Mayor, if one may venture a guess, indicates that 

 the form may belong to Puccinia Cenchri Diet. & Holw., which 

 occurs in the West Indies on Cenchrus, but is not reported on 

 Anthephora. 



Uredo quinqueporula sp. nov. 



II. Uredinia amphigenous, scattered, few, elliptical to oblong- 

 linear, 0.5-2.5 mm. long, early naked, chestnut-brown; paraphy- 

 ses none; urediniospores ellipsoid or oblong-ellipsoid, 19-24 

 by 25-33 )Li; wall moderately thick, 1.5-2.5 /u, golden- to cinna- 

 mon-brown, echinulate, the pores 5, sometimes 4, equatorial. 



On Torresia macrophylla (Thurb.) Hitchc. {Savastana macro- 

 phylla Beal, Hierochloa macrophylla Thurb.), Glendale, Oregon, 

 July 17, 1 914, H. S. Jackson 141 1. This non-paraphysate grass 

 rust is especially noteworthy in having the larger part of its 

 urediniospores equatorially five-pored.
