nearly so, although more commonly it is horizontal as in the 

 case of the plants growing further north. On the dunes back of 

 the beach opposite Miami, plants with erect stems ten to twelve 

 feet tall are quite common. There is a small grove in the pine- 

 lands north of Arch Creek on the mainland seven or eight miles 

 north of Miami, consisting of taller plants, the stems of some 

 measuring twenty-six feet in height. The upright plants have 

 no floral characters to separate them from the horizontal-stemmed 

 ones, but the foliage is usually more glaucous. I have not yet 

 been able to discover the reason for the plants assuming the two 

 distinct habits, for both the erect and horizontal-stemmed forms 

 occur in close proximity, growing both in deep sand or on almost 

 bare coral rock. 



Chrvsobalanus pellocarpus Mey. This species as it occurs 

 in Florida is strongly contrasted with Chrysobalamis Icaco L. 

 The plants of the latter species are mainly confined to the sand 

 dunes near the beach and the contiguous regions. In the ever- 

 glades it is apparently^ replaced by Clirysobalanns pellocarpus 

 Mey. This species differs from C. Icaco in its smaller, narrower, 

 usually abruptly pointed or rounded leaf-blades, the smaller 

 flowers with typically spatulate petals, and the obovoid or oblong- 

 obovoid drupes with narrow sharp-ridged stones. 



Alvaradoa amorphoides Liebm. The discovery of this 

 tropical plant in Florida has already been recorded * but hitherto 

 it was known within our limits only as a shrub. In the ham- 

 mocks near the trail that crosses Long Prairie a few miles north- 

 east of Camp Longview small trees varying between twenty and 

 thirty feet in height are not uncommon. It attains about the 

 same development as 1 ctrazygia bicolor, with which it grows. 



Suriaxa maritima L. The greatest height to which this sea- 

 shore plant was formerly known to attain seems to have been 

 about six feet. I have seen it growing at many places on the 

 coast of South Florida and with the exception of the instance to 

 be mentioned the specimens were invariably less than six feet 

 tall. However, in the fall of 1904, I discovered it growing as a 

 tree on the western shore of Elliott's Key at a point about twenty-
