 conspicuous, short-pedicelled : petals oblong, 6-8 mm. long, those of both series nearly 

 similar, obtuse, leathery : carpels pubescent when young.

4. As-nvna obovata ( Willd. ) Nash. A shrub or small tree, 1-3 m. tall. Stems 

 much branched, clothed with a grayish brown bark ; branchlets, petioles and the lower sur-

 hairs : leaf-blades obovate, or the smaller ones often oval, 4-10 cm. long, glabrous above ; 

 petioles 3-5 mm. long : flowers sessile or nearly so, terminating the branchlets : sepals 

 ovate to oval, 10-12 mm. long, tomentose when young, glabrate: petals yellowish white, 

 glabrous, the outer obovate, 5-6 cm. long at maturity, the inner smaller : fruit not seen. 



In pine lands, peninsular Florida. Spring. Fruit ripening in summer. 



5 Asimina spec<6a Nash. A shrub, 6-12 dm. tall. Stems clothed with a smooth 

 gray bark ; branchlets, as well as the peduncles and both surfaces of the young leaves 

 densely tomentose with yellowish or tawny hairs : leaf-blades oblong, narrowly obovate or 

 obovate, 7-14 cm. long, leathery, reticulated, tomentose on both sides, sparingly so above 

 at maturity ; petioles 3-7 mm. long, densely tomentose : flowers sometimes accompanied 

 by branchlets from the axils of the deciduous leaves of the preceding year : pedicels 7-18 

 mm. long: sepals ovate, 6-8 mm. long, tomentose : outer petals oval or obovate, 4 5 cm.
