ARTHUR AND JOHNSTON: UREDINALES OF CUBA 141 
aecia, as listed above, have been examined in a collection in the 
herbarium of Dr. W. G. Farlow at Cambridge, Mass., and are 
characteristic of the species in both gross and microscopic char- 
acters. They are accompanied by pycnia. The packet is marked 
1857-8, but the year is undoubtedly 1858, as Wright was in Cuba 
December, 1858, but not there in December, 1857 (cf. Underwood, 
Wright's explorations in Cuba, Bull. Torrey Club 32:293. 1905). 
This is the only collection on this host genus yet made in America. 
70. PUCCINIA SMILACIS Schw. Nat. Ges. Leipzig 1:72. 1822. 
ON SMILACEAE: 
Smilax havanensis Jacq., San Antonio de los Bafios (Prov. 
Habana), June 11, 1916, II, Johnston 783. 
A seemingly rare rust in the West Indies, having been col- 
lected only once before, in Porto Rico. 
71. PuccINIA CANNAE (Wint.) P. Henn. Hedwigia 41:105. 1902. 
ON CANNACEAE: 
Canna indica L., Santiago de las Vegas, July 2, 1906, Baker 
(Barth. Fungi Columb. 2387, Sydow Ured. 2114), July

Oriente), April 18, 1916, II, Johnston 662. 
Canna sp., Soledad, Cienfuegos (Prov. Santa Clara), Nov: 
4, 1915, Johnston 220. 
Only uredinia and telia are known for the species, and the 
character of the remaining part of the life cycle can not be pre- 
dicted. It is also reported from Jamaica and Porto Rico. 
72. PUCCINIA PoLvGONI-AMPHIBII Pers. Syn. Fung. 227. 1801. 
ON POLYGONACEAE: 
Persicaria punctata (Ell. Small (Polygonum punctatum

Мау 2, 1916, II, Johnston 517; San Antonio de los Вайоз 
(Prov. Habana), June 11, 1916, II, Johnston 777. 
These collections show an abundance of uredinia, but no telia, 
being the usual condition on this host. The first record for the 
West Indies was from Haiti in 1910, and it was lately taken in 
Porto Rico. It isa common rust in temperate regions both north 
and south, as well as in the Old World. Cultures have been con-
