16 ORCHIDACEM 



This species was first described by H. G. Reichenbach in 1865, 

 as an Aeranthus. The genus Aeranthus as now understood com- 

 prises several species confined to Madagascar and the Mascarene 

 Islands. The American species which it formerly included, but 

 which are quite distinct, have been removed to the genus Cam- 

 pylocentrum. The known species of Campylocentrum, about 

 twenty, are distributed through the American tropics and sub- 

 tropics, the most northern habitat being peninsular Florida. The 

 species may be divided into two sections, one with leafy, the other 

 with leafless, plants ; or, as in Campylocentrum Poeppigii, species 

 of the second section may possess minute fleshy terete leaves. 

 In the latter section there are about seven species, including C. 

 porrectum. 



Campylocentrum porrectum was discovered by Charles Wright 

 in Cuba between 1860 and 1865. That it is a native of Florida 

 was first made known to me by Mr. T. L. Mead, who found plants 

 near the nursery of Reasoner Brothers at Oneco, Manatee County. 

 Later, plants were collected in the same locality, and in Lee 

 County, about 125 miles farther southward. The plants are 

 epiphytic on Juniperus harhadensis, Acer ruhrum, and Cephalan- 

 thus sp. near Oneco, and on Fraxinus caroliniana near Everglade. 

 The glands on the ovary are often few, and in dried specimens 

 obscure. The bulbous swelling of the pedicel where it is articu- 

 lated with the stalk of the ovary, the vesiculous spur seemingly 

 composed of two coalescent bladders, and the erect tubercle on 

 the lip, are peculiar characters which should render this species 

 distinguishable from its congeners.
