sporangium Ellisii Berk, might be found. Also the presence of 

 Sabina barbadense (L.) Small would indicate thab Gymnospo- 

 ranghun be^nnudiamuii Earle might be collected in the state. 



For this reason I made a collecting trip into southern Alabama 

 early in March, 1908, for the purpose of gathering material. 

 In order to become acquainted with Gymnosporangiwn bermu- 

 diamim as it occurs on its host, Sabina barbadense, I went first 

 to Biloxi, Miss., the type locality for this species. 



While on the trip I discovered some new combinations. 



New Hosts 



Gymnosporangium inacropiis Link, on Sabina barbadense (L.) 

 Small (new host). 



Collections were made at Biloxi, Miss., March 3, 1908 ; Coden, 

 Ala., March 6, 1.908; Bayou Labatre, Ala., March 8, 1908. 



At Biloxi, Miss., the Gymnosporangium macropiis and Gym?to- 

 sporangium bermudianum were found growing on the same tree. 



Gymnosporangium globosum Farl., on Sabina barbadense (L.) 

 Small (new host). 



Collections were made at Biloxi, Miss., March 3, 1908, and 

 Bayou Labatre, Ala., March 6, 1908. 



On this trip the gap in the known distribution of Gymnospo- 

 rangium bermudia7tum was partly filled out by collections made 

 at Bayou Labatre, Ala., March 6, 1908, and at Spring Hill, Ala., 

 March 8. The collections of this species are complete enough 

 now to enable us to say that it occurs all along the Gulf Coast 

 from Florida to Louisiana. The species probably extends west 

 to Texas and perhaps farther. 



Perhaps the most important collections, as far as extending the 

 known range of certain species is concerned, were those of the 

 two species of Gymnosporangium found on the white cedar, 

 Chamaccyparis tliy aides (L.) B.S.P. As stated previously, the 

 presence of the white cedar and both Amelanchier canadensis and 

 Aronia arbntifolia gave the requisite conditions for either one or 

 both of the two species to be found. However since neither had 

 been collected in the south my hope of finding them was small 

 indeed.
