A shrub or small tree 3-5 m tall, sometimes with a short trunk 

 i.5 dm in diameter, clothed with ashy-gray or brownish rough or 

 rimose bark, the slender pendulous branches frequently armed 

 with chestnut-brown or gray spines 5. mm -i.5 cm long: leaves cu- 

 neate or spatulate, or on leading shoots obovate-cuneiform, the 

 blades i.5-3 cm long, 5-1 5 mm wide, or broader on the shoots, 

 wedge-shaped or more abruptly contracted at the base, pointed or 

 rounded at the apex, the margins glandular, dentate or lobed ; 

 they are glabrous or glabrate at maturity, and when young are 

 more or less pubescent on both surfaces, firm to subcoriaceous in 

 texture, bright green, fading with tones of yellow, orange and 

 brown: petioles 5-1 5 mm long, margined, glandular, pubescent, at 

 least when young : flowers i2-i5 mm wide, opening about the 20th 

 of March and when the leaves are about half grown ; they are 

 solitary or in simple, 2-4-flowered corymbs which terminate short 

 leafy branchlets or fascicles of leaves : pedicels and hypanthium 

 tomentose : sepals 4-5 mm long, glandular-serrate, reflexed after 

 anthesis : stamens about 20, the anthers light yellow : fruit, which 

 ripens in August, pyriform or short-pyriform, j-g mm thick, red at 

 maturity, the flesh soft : nutlets 3-5, 6-y mm long, the lateral sur-
