WOOTON AND STANDLEY—FLORA OF NEW MEXICO, 175 
1. Celtis reticulata Torr. Ann. Lyc. N. Y. 2: 247. 1824. 
Type Locauty: ‘‘ Base of the Rocky Mountains,’’ Colorado or New Mexico. 
RanGeE: Colorado to Arizona and Texas and southward. 
New Mexico: Sierra Grande; Santa Rita; Burro Mountains; Black Range; Florida 
Mountains; Guadalupe Canyon; Organ Mountains; Guadalupe Mountains; White 
Mountains. Dry hills and canyons, in the Upper Sonoran Zone, 
The berries of this tree are edible and were often eaten by the Indians, 
35. MORACEAE. Mulberry Family. 
1. MORUS L. Mutperry. 
Ours a small scraggy tree with alternate ovate small (3 to 6 cm. long) serrate leaves, 
these usually 3 to 5-lobed, acute; flowers dicecious, small and inconspicuous, green; 
fruit technically a ‘‘multiple fruit,’’ consisting of a cylindrical or oblong cluster of 
separate 1-seeded berries, the whole appearing to be a single fruit. 
Morus alba L, is extensively cultivated in New Mexico as a shade tree and for its 
fruit. The trees are of two kinds, staminate and pistillate, the former being much 
more desirable as shade trees, This species occasionally occurs as an escape.

Dry hills and canyons, in the Upper Sonoran Zone. 
We are unable to distinguish from typical Morus microphylla the numerous plants 
to which Doctor Greene’s names were given. There is some slight variation in the 
outline of the leaves, but, as shown by the extraordinary variation in those of indi- 
viduals of Morus rubra, the species of this genus can not be separated by leaf form 
alone. This inconstancy is strongly realized when mature leaves and those from 
young sprouts of the same tree are compared. There seems to be no variation in 
pubescence. 
The type of Morus vernonit came from the Chisos Mountains of western Texas; 
that of M. vitifolia from the Dona Ana Mountains ( Wooton & Standley in 1906); that of 
M., goldmanii from the Little Florida Mountains (Goldman in 1908); that of Mf. betuli- 
folia from the Organ Mountains (Standley in 1906); that of M. canina from Dog Spring 
(Mearns in 1892); that of M. albida from Berendo (misspelled Berend in Doctor 
Greene’s citation of the locality) Creek ( Metcalfe in 1904); that of M. crataegifolia from 
the Blue River, southeastern Arizona; that of M. radulina from Beaver Creek, Arizona; 
and that of M. confinis from Santa Rita Mountains, southern Arizona. 
The species is a stunted, irregular tree 5 meters high or less, with small, scabrous 
leaves. The red fruit is palatable when ripe, having a pleasant acid flavor. The 
trees occur chiefly in arroyos of the foothills and on the drier slopes of the mountains.
