ARTHUR AND JOHNSTON: UREDINALES ОЕ CUBA 117 
18. RAVENELIA SILIQUAE Long, Bot. Gaz. 35: 118. 1903. 
On MIMOSACEAE: 
Vachellia Farnesiana (L.) W. & A. (Acacia Farnesiana 
Willd.), Santiago de Cuba, April 30, 1916, II, Johnston 
664. 
This collection, the first one seen from the West Indies, shows 
the usual abundance of uredinia on the pods. The species also 
occurs in Central Mexico. No pycnia or telia are known for it, 
and it has until recently been taken only on the fruit of the host. 
Long (Bot. Gaz. 64:64. 1917) reports it on branches and leaves. 
19. RAvENELIA PrrHECOLOBII Arth. Bot. Gaz. 39: 394. 1905. 
Ох MIMOSACEAE: : 
Pithecolobium tortum Mart., Sierra de los Ceballos, Isle of 
Pines, March 2, 1916, III, Britton & Wilson 15358. 
This is the first record of the species for the West Indies, being 
previously known from southern Florida and Mexico, and is also 
the first record for this species of host. The pycnia of the species 
are yet unknown. 
20. RAVENELIA LysILOMAE Arth. Bot. Gaz. 39: 392. 1905. 
Dendroecia Lysilomae Arth. Résult. Sci. Congr. Bot. Vienne 
340. 1906. 
ON MIMOSACEAE: 
Lysiloma bahamensis Benth., Punta Sabanilla, Cienfuegos 
Bay (Prov. Santa Clara), Feb. 24, 1910, III, Britton, 
Earle & Wilson 4586. 
This collection shows telia but no uredinia, although a few 
urediniospores are present. The species was originally placed in 
the genus Dendroecia on evidence similar to this. Dietel states 
(Beih. Bot. Centr. 20: 375. 1906) that well-developed uredinia 
were found by him upon the type collection, made by E. W. D. 
Holway at Iguala, Mexico, on L. tergemina. A more ample por- 
tion of this collection than was originally available has enabled the 
senior author to confirm the statement made by Dietel. On this 
evidence, which completes the life history, the species is returned 
to the genus Ravenelia, where it evidently belongs. The above col- 
lection gives the first station known outside of Mexico, and adds 
another species of host.
