28 Arthur : New species of Uredineae 



paler than the urediniospores, and both are unlike the usual legu- 

 minous species of Uromyces. 



Puccinia Dolichi sp. no v. 



II. Uredinia hypophyllous, irregularly scattered, round, small, 

 0.25 mm. across, soon naked, chestnut-brown, pulverulent, ruptured 

 epidermis inconspicuous ; urediniospores globose, small, 19-23 fi in 

 diameter; wall chestnut-brown, rather thin, 1.5-2//, minutely 

 echinulate, pores 3, or rarely 4, equatorial. 



III. Telia not seen ; teliospores in the uredinia, oblong, very 

 large, 30-40 by 50-70 /i, acute or acuminate at the apex, rounded 

 or obtuse at base, slightly or not constricted at septum ; wall semi- 

 opaque, chocolate-brown, thick, 3 u, thickened and prolonged into 

 a prominent, lighter-colored rostrum at apex, 10-15 /i, surface 

 coarsely verrucose, with very low tubercles, smoother or smooth 

 on the rostrum; pedicel colored next the spore, 6-12 fi thick, 

 once length of spore.

Puccinia Fimbristylidis sp. nov. 



II. Uredinia chiefly hypophyllous and caulicolous, oblong, 

 0.5—1 mm. long, soon naked, yellow, pulverulent, ruptured epider- 

 mis noticeable ; urediniospores broadly elliptical or globoid, 1 5-20 

 by 18-23 /i, wa U brownish-yellow, medium thick, 1.5/1, sparsely 

 and evenly echinulate with low points, pores 2, equatorial and 

 opposite. 



III. Telia chiefly hypophyllous and caulicolous, subepidermal, 

 covered with the brown epidermis, irregularly oblong, 0.1-0.5 mm. 

 long, or punctiform, compound, each component sorus round, sur- 

 rounded by abundant, dark -brown, hyphal stroma ; teliospores 

 oblong, 16-19 by 34-50 /i, slightly constricted at septum, acute 

 or obtuse at apex, somewhat narrowed at base, wall smooth, 

 golden-brown, medium thick, 1-1.5/i, thicker at apex, 4-9 fx ; 

 pedicel very short, colored.

 of Morel os, Mexico, Sept. 27, 1898, E. W. D. Holway ^227 ; F. 

 Hokvayana Fernald, Chapala, State of Jalisco, Mexico, Sept. 9, 1899,

 1904, G. P. Clinton 48 ; the last with uredinia only. 



This species diners materially from Puccinia Eleocharidis Arth. 

 in the telial characters, although the urediniospores have a close
