32O. DlPHOLIS SALICIFOLIA BuSTIC CASSADA. 35 



grained with fine medullary rays and of a rich brownish red color with 

 lighter sap-wood. It is susceptible of a beautiful polish. The odor of 

 the fresh wood is strongly suggestive of that of vinegar, and hence, 

 perhaps, its Bahaman name, Sour-wood, but in flavor it is very bitter.

USES. The wood is occasionally used for knees and timbers in 

 boat-building, though not abundant enough to have a recognized place 

 in commerce. Its handsome color and other desirable qualities strongly 

 commend it for use in furniture, interior finishing, etc. 



ORDER BORRAGINACE^: BORAGE FAMILY. 



Leaves simple, persistent, both alternate and opposite or sub-verticillate 

 without stipules. Flowers regular, perfect, in terminal or axillary compound 

 cymes; calyx usually 5-lobed, persistent; corolla with usually 5 spreading lobes, 

 hypogenous; stamens, 5, alternate with the lobes of the corolla and inserted on 

 its tube, with filiform filaments and introrse 2-celled anthers longitudinally 

 dehiscent; pistil with usually 2- or 4- celled ovary and single style dividing into 

 2 branches with capitate stigmas ; ovules solitary in each cell. Fruit drupaceous, 

 tipped with the remnants of the style and subtended by the persistent calyx, and 

 the pit containing 2-4 ascending seeds. 



A family of about 85 genera of mostly herbaceous plants of tem- 

 perate regions. It is represented in warm climates also by a few trees, 

 three genera of which are native to extreme southern United States. 

 The above description applies mainly to the arborescent species. 



GENUS BOURRERIA P. BROWNE. 



Leaves both alternate and opposite, persistent, obovate-oblong. Flowers 

 white, with slender bracteolate pedicels in terminal compound cymes ; calyx bell- 

 shaped, persistent, with 5 valvate lobes ; corolla with 5 broadly spreading rounded 

 lobes ; stamens with thread-like filaments and oblong slightly wrinkled anthers ; 

 pistil with sessile incompletely 4-celled ovary, tapering to a 2-parted style with 

 capitate stigmas ; ovules anatropous and solitary. Fruit a subglobose drupe with 

 thin flesh and a stone separable into 4 thick-walled bony nutlets, each with a 

 spongy many-ridged appendage on the back and with flattened inner faces. 



A genus of about 18 species of trees and shrubs of the American 

 tropics, two being found on the Keys of Southern Florida. It is named 

 after J. A. Bourrer, an apothecary of Nuremberg.
