GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 841 
Mascagnia macroptera (Moc. & Sessé) Niedenzu. 
This species has a wide range in tropical and subtropical portions of Mexico, from 
the type locality near Monterey, Nuevo Leén, to southern Sonora and Lower Cali- 
fornia. It was first noted by us on the Peninsula, about 20 miles east of San Ignacio, 
where specimens bearing flowers and fruit were collected October 19. From this 
point southward to near La Paz it was noted along canyons in the hill country. 
Flowering specimens in the U. 8. National Herbarium were collected by Palmer at 
Mulegé in 1887 and at Santa Agueda, March 4-6, 1890. The species grows as a small 
shrub, often climbing over other vegetation. 
EUPHORBIACEAE. Spurge Family. 
Acalypha californica Benth. 
Flowering specimens of this species were taken at the mouth of La Providencia 
Canyon, where it opens on the desert at the east base of the San Pedro Martir Moun- 
tains, June 26. It was rather common, growing here as a shrub 0.5 to 1.2 meters high. 
‘Cnidoscolus palmeri (8S. Wats.) Rose. 
Collected at about 450 meters in the hills along the backbone of the Peninsula, 
about 20 miles east of San Ignacio, where it seemed to be rare. We have no other 
record of its collection since the type was taken near Guaymas, Sonora, by Palmer. 
As seen by us, the plant is a shrub about a meter high. Our specimens are in flower 
and fruit and have the leaves and tender branches armed with stinging hairs, such 
as characterize some of its congeners, known locally as “mala mujer’’ in Vera Cruz 
and other parts of tropical Mexico. The species was originally described under the 
name Jatropha palmer. 
Croton magdalenae Millsp. 
First noted about 5 miles southwest of El Potrero on the way from Mulegé to La 
Purisima. It was common at Comandt, and a Croton which we took to be the same 
was seen at intervals along the route southward to Cape San Lucas. It grows as a 
shrub 2 to 3.5 meters high. A specimen in fruit was taken about 5 miles southwest 
of El Potrero, October 31. Reported by Brandegee from San José del Cabo and in 
the mountains. Brandegee remarks that some forms are much less pubescent or 
hirsute than the type from Magdalena Island. 
Croton californicus Muell. Arg. 
In the vicinity of La Paz and at the lower elevations southward to Cape San Lucas 
this species was noted in abundance as a shrub 1.2 to 1.5 meters high. <A flowering 
specimen was taken at La Paz, February 17. Millspaugh records specimens in fine 
flower and fruit collected by Brandegee on Magdalena Island, January 23. 
Ditaxis brandegei (Millsp.) Rose & Standl. 
A specimen of this species in flower was taken on the shore of La Paz Bay, near 
Rodriguez, December 16. A shrub about a meter high. Not noted in abundance. 
The type was collected by Brandegee at San Gregorio. 
Euphorbia californica Benth. 
From near Tinaja de San Esteban, 25 miles north of San Ignacio, southward this 
species was noted at intervals, but was more common at the lower elevations in the 
Cape District south of La Paz. It grows as a shrub 1.2 to 1.5 meters high. A speci- 
men in flower and with young leaves just coming out was taken at Tinaja de San 
Esteban and one in flower and fruit between El Cajén and El Sacatén, December 28. 
Brandegee records this species from Todos Santos.
