THE FLORA OF LOUISIANA 187 



ridges rising sometimes several hundred feet, separated by very 

 precipitous ravines or narrow valleys. In the southern portion 

 of the parish the ridges are not so elevated and the level areas are 

 more extensive. The parish affords a particularly inviting field 

 for botanical investigation as unlike the similarly formed adjoining 

 parish of East Baton Rouge, which is almost completely cleared 

 and under cultivation, this parish still contains large tracts of 

 undisturbed woodlands, explained by the fact that the large 

 estates of the original owners who settled there in the latter part 

 of the eighteenth century have never been broken up and sub- 

 divided into small farms. The forests of this region are unsur- 

 passed anywhere. Perhaps their most striking feature is the mag- 

 nificent growth of magnolia trees (M. foetida) which is in some 

 places almost the exclusive tree, some of them attaining to a 

 height of a hundred feet before branching. It is perhaps also 

 worth recording that the jujube tree, Zysiphus vulgaris, is well 

 naturalized in this region, occasionally forming extensive thickets. 

 Other trees characteristic of the region are the following : 



Ilex opaca, which here attains a size Liquidambar styraciflua. 



not approached elsewhere. Fraxinus americana. 



Celtis mississippiensis. Ostrya virginica. 

 Carya cordiformis. Here conspicuous Carpinus caroliniensis . 



by its white bark. Platanus occidentalis 



Carya alba. Tilia leptophylla. 



Carya porcinaf Prunus caroliniensis. 



Quercus alba. Prunus sp. 



Quercus texana. Symplocos tinctoria. 



Quercus stellata. Oxydendron arboreum. 



Quercus Michauxii. Vaccinium arboreum. 



Quercus nigra. Bumelia lanuginosa. 



Quercus phellos. Bumelia lycioides. 



Quercus falcata. Pinus glabra. 



Quercus pagodaefolia. Cornus florida. 



Quercus acuminata. Not common. Cercis Canadensis. 



In this paper I wish especially to record first the number of 

 plants which are found here but no where else in Louisiana, second 

 the large number of apparently mountainous species which occur 

 here and have never been recorded in the intervening territory 

 a distance of about five hundred miles.
