GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 859 
tends into northern Lower California. It differs from <A. menziesii in having the 
leaves tomentose and green beneath instead of glabrous and glaucous and in its more 
crowded inflorescence and larger calyx lobes. The type was collected by us near La 
Chuparosa, on the upper slope of the Sierra de la Laguna, January 23, 1906.° 
The species is rather abundant and generally distributed along with the oaks in 
the Upper Sonoran Zone from about 1,200 meters elevation to the summit of the 
Sierra de la Laguna. It occurs disconnectedly here on the mountain tops, like 
numerous other species whose congeners are absent in the wide desert interval to the 
northward. 
Arctostaphylos sp. 
A specimen of an undetermined and perhaps undescribed manzanita bearing ripe 
fruit was taken at about 1,500 meters altitude along the trail on the west slope of the 
San Pedro Martir Mountains between Rancho Santo Tom4s and San Antonio, July 28. 
The species is less abundant than A. glauca, with which it occurs. In habit of growth 
it is similar to glauca, reaching a height of 1.8 to 3 meters. 
Arctostaphylos bicolor (Nutt.) A. Gray. MANZANITA. 
Common in places along the steep Upper Sonoran slopes of the hills fronting the 
coast near Ensenada and eastward to about 780 meters altitude near Ojos Negros. 
Beyond this the open plain in San Rafael Valley, largely Lower Sonoran in character, 
is unsuitable for its growth. It was collected in fruit about 15 miles east of Ensenada, 
May 31. Brandegee records the specie: from Rancho Viejo. 
Arctostaphylos pringlei Parry. MANZANITA. 
Abundant in the Transition Zone on the upper slopes of the Sierra del Pinal and 
San Pedro M&rtir mountains. It is associated with A. glauca and the two form dense 
thickets between 2,100 and 2,250 meters altitude near La Grulla. It was taken in 
flower at Laguna Hanson, June 7, and in ripe fruit at La Grulla, July 20. Brandegee 
states that this manzanita blooms later and is more viscous, with redder bracts and 
flowers, than the other species of the general region. 
Arctostaphylos glauca Lindl. MANZANITA. 
The most abundant manzanita in the Peninsula. It ranges upward, mainly in the 
Upper Sonoran Zone, from about 840 meters near La Huerta and Trinidad Valley to 
near the summit of the Sierra del Pinal and on the warmer slopes to above 2,100 meters 
altitude in the San Pedro Martir Mountains. It forms thickets which at the higher 
levels are largely mixed with A. pringlei. Fruiting specimens were collected at La 
Huerta, June 2; El Pifién, July 5; La Grulla, July 20. 
Arctostaphylos oppositifolia Parry. MANZANITA. 
This tall, slender-leaved species, so unlike the other manzanitas, is common in 
places on the Upper Sonoran slopes along the west side of the San Pedro Martir Moun- 
tains. Specimens in fruit were taken at the 1,500 meter level in descending from 
Rancho Santo Tomds to San Antonio, and at 1,020 meters on a ridge a few miles 
west of San Antonio, on the trail to San Quintin. It is a larger species than the 
other manzanitas of the Peninsula, commonly reaching a height of 4.5 meters. 
EBENACEAE. Ebony Family. 
Brayodendron texanum (Scheele) Small. ZAPOTILLO. GUAYPARIN. 
A persimmon tree about 2 meters high, probably of the species listed by Brandegee 
under this name, but perhaps representing a distinct species, was first noted among 
the sand dunes at Cape San Lucas, where a specimen was collected. The species
