 flesh, inclosing 4 bony nutlets ridged on the back. [Commemorates J. A. 

 Beurer, a Nuremberg apothecary.] About 25 species of tropical America. Type

1. Bourreria ovata Mi'ers, Ann. Mag. Nat. Hist. IV. 3: 203. 1869. 



A shrub or small tree up to 10 m. high or perhaps higher, with a trunk 

 sometimes 1.5 dm. in diameter, the bark reddish-brown, the twigs and leaves 

 glabrous or very slightly pubescent, or shoots from stumps sometimes with 

 pubescent foliage. Petioles rather stout, 4 cm. long or less; leaves oblanceolate, 

 oval or nearly orbicular, 412 cm. long, sub coriaceous, rounded or emarginate 

 at the apex, mostly narrowed at the base; cymes commonly many -flowered, 

 5-10 cm. broad; pedicels short; calyx 5-6 mm. long, irregularly 5-lobed; 

 corolla about 10 mm. long, its lobes nearly orbicular; styles connate; filaments 

 glabrous; drupe ,orange-red, 10-15 mm. in diameter, subglobose. 



Scrub-lands and coppices, throughout the archipelago from Abaco and the Berry 

 Islands to Grand Turk, Inagua, the Anguilla Isles and Cay Sal : Florida ; Cuba. 



The species is composed of a number of races with the leaves varying from 

 oblanceolate to suborbicular ; the leaves are usually quite glabrous but those on 

 shoots from cut stumps are pubescent. The species is distinct from B. tomentosa 

 (Lam.) Griseb. to which it has been referred by Grisebach and by Dolley ; it was 

 referred to B. havanensis Miers, by Hitchcock and by Mrs. Northrop, and recorded by 

 Schoepf as Ehretia tinifolia and E. Beureria. Catesby, 2 : pi. 79. Closely related to 

 B. succulenta Jacq. STRONG-BACK.
