another species of RavcncUa, R. papillifcra Syd. on Cassia biflora

9. RAVENELELIA HUMPHREYANA P. Henn. — On 

 Poijiciana pulchcrrima L. (Caesalpinia pulcherrima Lev.), (host 

 det. by R. F. Griggs), Gualan, Depart. Zacapa, alt. 122 m., Dec. 

 27, 1906, no. 5427. 



A common species in the North American tropics wherever 

 this host occurs. The type of R. Huniphrcyana was said to be 

 on Cassia sp., but a careful examination shows that it is undoubt- 

 edly Poinciana pulcherrima. As pointed out by W. H. Long 

 (Jour. Myc. 12:236 1906), Ravenelia pulcherrima Arth. is a 

 synonym of R. Humphreyana.

 hiis poliophyllus Focke (host no. 4775), Autigua, Depart. Sacate-
