The material shows good development of this rather inconspicu- 
ous rust. No closely related form is known. The host genus is 
American ; the species extends from Mexico and the West Indies 
to Patagonia. 
155 - PucciNiA FARiNACEA Long, on Salvia coccinea B. Juss. 
(Lamiaceae) , El Gigante, July i6, 1915, 8jjo. The sec- 
ond time the host has been reported for this rust, the first 
collection of it being made in Texas in 1898.

gregated on yellowish, indefinite spots, punctiform, slightly ele- 
vated, dark or even blackish brown, 0.1-0.25 mm. across, subepi- 
dermal, lenticular, firm ; teliospores imperfectly catenulate in 
chains of 2-4, closely compacted, oblong, 10-16 by 23-27 /x; wall 
light cinnamon-brown, thin, 1-1.5/x, outer wall of terminal spores

It is most fortunate that Professor Stevens was able this season 
to find more complete material of this interesting rust. The telia 
on the present collection, which consists of about twenty leaves, 
are abundant and well matured. They bear out the prediction, 
made in the introduction (p. 170), as to the genetic position. 
Additional Hosts for Porto Rican Species
