﻿FIVE UNDESCRIBED SPECIES OF RAVENELIA 



W. H. Long 



The five species described in this article were collected during 

 1914 and 1915. Three of them are from Texas, one is from Florida, 

 and one from Arizona. 



There are known now to occur in Texas n species of Ravenelia, 

 including 3 of the new species described in this paper, namely, 

 (1) Ravenelia arizonica Ellis and Ev. on Prosopis juliflora, (2) R. 

 versatilis (Peck) Dietel on Acacia greggii, (3) R. igualica Arthur on 

 Acacia filiculoides, (4) R. texensis Ellis and Gall, on Acuan jamesii 

 and A. acuminata, (5) R. fragrans Long on Mimosa fragrans, 

 (6) R. cassiaecola Atk. on Chamaecrista multipinnata (?), (7) R. 

 longiana Syd. on Cassia roemeriana, (8) R. papillifera Syd. on 

 Cassia lindheimeriana, and the 3 species here described: (9) R. 

 roemerianae on Acacia roemeriana, (10) R. morongiae on Morongia 

 uncinata, and (11) R. thornberiana on Acacia constricta paucispina. 

 The types of 7 of these species (R. texensis, R. roemerianae, R. 

 thornberiana, R. fragrans, R. longiana, R. papillifera, and R. moron- 

 giae) were collected in Texas, while the type locality of the last 

 4 named is Austin, Texas. 



Many Mexican species of this genus undoubtedly will be found 

 in southwestern Texas, especially in the territory lying between 

 El Paso and Brownsville along the Rio Grande. R. cassiaecola is 

 reported for the first time west of the Mississippi River, the writer 

 having collected it at Denton, Texas. 



Two closely related genera, Neoravenelia and Pleoravenelia, are 

 also represented in this state, the former by N. Holwayi (Dietel) 

 Long on Prosopis juliflora, and the latter by P. Hieronymi (Speg.) 

 Long on Vachellia farnesiana. P. epiphylla (Schw.) Long should 

 be found also in the northeastern part of the state, since the writer 

 has recently collected this species in southern Arkansas near the 

 Texas border.
