ARTHUR AND JoHNsTON: UREDINALES OF CUBA 135 
ON FABACEAE: | 
Dalbergia Amerimnum Benth., Baracoa (Prov. Oriente), 
April 14, 1916, II, Johnston 639. 
The collection shows an abundance of uredinia, but no telia. 
The characters agree well with the description of the species as 
given in Sydow, Monog. Ured. 3: 186, but no original specimen 
has been seen. Although heretofore recognized only from Natal 
in southern Africa, yet upon comparing the Cuban collection with 
the one distributed in Sydow, Uredineen 2150, which was collected 
by E. J. Butler at Pusa, India, and issued as Uredo Sissoo, the 
agreement seems perfect, and the wide tropical distribution be- 
comes apparent. The description by Dietel in Hedwigia states 
that the paraphyses are septate, having a cross wall at the middle. 
That appears to be the case both in the West and East Indian 
material, but a more critical examination shows that the appear- 
ance is due to the arrangement of the cell contents, and not to a 
cellulose wall. The spores are inclined to be bent to one side, 
almost kidneyform at times. The two pores of the urediniospores 
are easily seen. 
The Uredo Dalbergiae P. Henn., on some species of Dalbergia 
from Brazil, has much smaller, paler and thinner-walled spores. 
The gross appearance of the sorus is also quite distinct, being 
smaller and more nearly round. 
The reference of this species to the genus Sphaerophragmium 
is based upon the statement by Dietel that he found a single sorus 
with some half dozen teliospores. The character of the life cycle 
is problematical.
