very spiny fruits, 1 cm. or more in diameter, these at first red but purplish at maturity, 
borne singly. They have a pleasant acid flavor when ripe, but are hard to eat on 
account of the spines, and partly ripe berries are very astringent. The flowers are 
orange-colored.

A very spiny shrub, from 1 to 1.5 meters high, occurring in the mountains almost 
throughout the State, at middle elevations. It is distinguished by the very spiny 
young branches which are light brown, by the long, curved, nodular spines, and the 
small, crowded, more or less glandular leaves whose petioles are usually shorter than 
the blades. The fruit is edible. 
The type of Ribes leptanthum veganum was collected by Cockerell along the Gallinas 
River below Las Vegas.

This gooseberry occurs in the mountains of the northern part of the State. It may 
be recognized by its rather slender young branches with few, small nodular spines, 
and the slender-petioled leaves which are commonly very numerous. The berries 
are wine-colored, about 8 mm. in diameter, smooth, and of good flavor.

The sycamore is usually found along the streams and in the mouths of rocky canyons 
near the bases of the mountains. It would probably grow in cultivation, but, so far as 
known to us, it has not been tried in the State,
