FRAXINUS ANOMALA Torr. In this queer ash the leaves are

alternate divisions that are either crenate or bluntly lobed and | 
oblique at base, nearly glabrous, but glandular on the rhachis; 
scorpioid cyme with a long naked peduncle; flowers on short 
pedicels; calyx white-hirsute, and slightly glandular, divisions 
linear-lanceolate, 1 mm. wide, 4 to 6 mm. long, veiny in age, 
with longitudinal nerves, slightly surpassing the ripe capsule; 
corolla bright blue, rarely white, about 1 cm. in diameter, 
divisions obtuse; stamens and style conspicuously exserted,

glandulosa and P. Neo-Mexicana. It grows on the adobe desert 
soil, and while not along the edges of irrigating ditches or 
washes, it was comparatively near by.

along the petioles which equal or surpass the blade in length; 
lower cauline leaves spatulate with long, broad petioles which 
are connate-clasping; upper, ovate-lanceolate, closely sessile by
