UREDINALES OF GUATEMALA 
487 
171. PucciNiA DE^LLENS Arth. & Holw. (on Bignoniaceae). 
Pithecoctenium muricatum DC. (?), Guatemala City, Feb.* 15, 1916, 
O, III, 492. 
A short-cycle rust occurring on the same host in Costa Rica. 
172. PucciNiA RuELLiAE (B. & Br.) Lagcrh. (on Acanthaceae). 
Justicia sp., San Felipe, Dept. Retalhuleu, Jan. 12, 1917, II, 6qi. 
The assignment of the collection on Justicia to this species is made 
without complete certainty, as no telia are present and no previous 
collection on this host is known. The species is a long-cycle one with 
all spore forms, and has usually been listed as P. lateripes Berk. & Rav. 
The same species was collected on Blechum Brownei (Swartz) 
Juss., by Kellerman, at Laguna, Lake Amatitlan, Jan. 17, 1906, II, 
5400, and reported by Kern in Journ. Mycol. /. c. and issued in 
Kellerm. Fungi Sel. Guat. j/, in both places under the name P. 
Tetramerii Seym. The rust on this host is often called P. Blechi La- 
gerh. 
173. Puccinia varia (Diet.) Arth. comb. nov. (on Acanthaceae). 
Acanthaceae (Ruellia or Jacobina?), Panajachel, Dept. Solola, Jan. 
30, 1915, II, iii, 160. 
The uredinia of the collection agree well with those of the type 
collection for Uredo varia Diet. (Hedwigia 36: 35. 1897), obtained at 
Rio de Janeiro, Brazil, in December, 1891, E. Ule 18 ly. The uredinio- 
spores have two equatorial pores. In addition to the uredinia the 
Guatemalan collection shows a few telia, which are epiphyllous, 
chestnut-brown, round, 0.3 mm. across, with the ruptured epidermis 
noticeable. The teliospores are broadly ellipsoid, 24-29 by 39-45 m> 
the wall chestnut-brown, 2-3 /x thick, slightly thicker above, 5-6 /x, 
smooth, with the pedicel tinted and up to 55 /jl long. As in the type 
collection the host remains uncertain, except as to the family. 
174. PuCciNiA Elytrariae P. Hcnn. (on Acanthaceae). 
Elytraria (Tubiflora) sp., Palin, Dept. Amatitlan, Dec. 24, 1916, 
A short-cycle rust, of which few collections have previously been 
known, and a,ll from Mexico or Costa Rica. 
175. Puccinia lateritia Berk. & Curt, (on Rubiaceae). 
Crucea calocephala DC, Guatem.ala City, Jan. 8, 1917, 684. 
Spermacoce podocephala DC, Solola, 5100 feet alt., Jan. 27, 1915, 
jjp; Panajachel, Dept. Solola, Jan. 3, 1917, 662.
