4. NEOCASTELA Small. 



Castela Turpin, Ann. Mus. Paris 7 : 78. 1806. Not Caslelia Cav. 1801. 



Shrubs with irregular, often thorn-like branches and branchlets. Leaves alternate, 

 relatively small ; blades broad, usually thick, entire, cordate or subcordate at the base. 

 Flowers polygamo-monoecious, solitary or few together in the leaf-axils. Sepals 4, short 

 and broad, well-united, rather persistent. Petals 4, much longer than the calyx, rather 

 broad, deciduous. Stamens S, usually about as long as the petals ; filaments short and 

 relatively slender; anthers rather short, often oval, notched at the apex. Ovary promi- 

 nentlv 4-lobed, the carpel-bodies distinct, sessile. Styles united, slender, elongate. Stigma 

 terminal, capitate. Ovules solitan' in each carpel. Drupes stout, relatively small, solitary 

 or Z-\ together, slightly oblique, scarcely flattened. 



Type species, Castela depressa Turpin. 



1. Neocastela depressa (Turpin) Small. 



Castela depressa Turpin, Ann. Mus. Paris 7: 79. 1806. 



A shrub with numerous branches and thorn-like branchlets mostly less than 1 cm. 

 long. Leaves spreading or reflexed, the blades ovate to ovate-lanceolate, 1-1.5 cm. long, 

 acute or abruptly sharp-tipped, revolute, bright-green and shining above, silvery-white 

 beneath, smooth, sessile ; calyx about 1 mm. long, the lobes acute, shorter than the tube; 

 petals purple, oval or obovate 2-2.5 mm. long; anthers mostly shorter than the filaments; 

 drupes obovoid, 1 cm. long or more, rounded at the apex.

5. CASTELARIA Small, gen. nov. 



Shrubs or small trees, with diffuse or irregular branches and thorn-like or spur-like 

 branchlets. Leaves alternate, relatively small ; blades thick, rather narrow or broad, entire, 

 or obscurely toothed, narrowed at the base and often short-petioled. Flowers dioecious, 

 solitary or few together in the axils. Sepals 4, broad, distinct or nearly so. Petals 4, 

 much larger than the sepals, broad, deciduous. Stamens 8, as long as the petals or nearly 

 so in the staminate flowers ; filaments subulate or sometimes very stout ; anthers ovoid to 

 oblong, not notched, sometimes apiculate at the apex. Ovary slightly 4-lobed, the carpel- 

 bodies distinct or nearly so, sessile. Styles wanting or very short. Stigma elongate, 

 introrse. Ovules solitary in each carpel. Drupes stout, solitary or 2-4 together, slightly 

 oblique, much flattened.
