merly land connections or at least scattered islands between Brazil and 

 Africa. 



The supposition that the plants may at some former time have migrated 

 by way of northeast Asia and northwest America, Engler considers un- 

 tenable because most of the plants occurring both in Africa and America 

 are not found in Asia. 



In recent years the cowhage has been collected in many parts of the 

 West Indian region. Specimens have been examined as follows: 



Jamaica, Constant Spring, Churchill, March 21, 1897; 



Cuba orientale, C. Wright No. 140; 



Porto Rico, Sintenis 2575, Heller 4403; 



Colombia, Santa Marta, Smith 638; 



Granada, St. Georges, Broadway, December, 1904; 



Venezuela, Tovar, Fendler 2200; 



Costa Rica, San Jose, Hoffman 47 ; 



Surinam, Hostmann 55; 



Brazil, Riedel ; 



Santo Domingo, Turpin ; 



Martinique, L. Hahn 446. 



From the Old World six different lots have been cultivated under their 

 introduction numbers as follows : 



21,954 From the Department of Agriculture, Buitenzorg, Java, through 



Dr. M. Treub. 

 24,422 From the same source as the preceding. 

 25,753 From Calcutta, India, through Consul-General W. H. Michael, 



the seed purchased from a seedsman. 

 From Coimbatore, India, through Rev. Geo. N. Thomssen. 



Most of the herbarium material from India and Africa seems referable 

 to this subspecies, but some specimens are aberrant, especially in pubes- 

 cence. Very few specimens possess mature pods and without these there 

 must remain doubt as to their precise identity. 



Stizolobium pruritum maculatum n. subsp. 



Very similar to S. pruritum officinale but pods larger, 8 to 9 cm. long; 

 young pubescence on the pod at first whitish, later turning pinkish and 

 finally tawny, all of the hairs changing color simultaneously; seeds 

 larger, distinctly compressed, gray, very densely speckled with black and 

 having few or no black marblings. 



The type specimen is in the Economic Herbarium of the Bureau of 

 Plant Industry, grown at Gainesville, Florida, in 1912, from S. P. I. No. 

 25,725 secured from the State Gardens, Baroda, India, presented by 

 B. F. Cavanaugh, Esq.
