GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 335 
CASSIACEAE. Senna Family. 
Cassia confinis Greene. 
This Cassia was noted at Tinaja de San Esteban, 25 miles north of San Ignacio, and 
thence southward at intervals to near La Paz, and on Espiritu Santo Island. It 
grows as a shrub 1 to 2 meters in height. Like many other plants of the region, it pro- 
duces flowers and fruit irregularly during a considerable part of, if not the entire, year. 
Specimens in flower and fruit were taken at Tinaja de San Esteban, October 5, and 
on Espfritu Santo Island, February 7. 
Cassia occidentalis L. - PALO DE ZORILLA. 
The “palo de zorilla,”’ as it is known to the people, is common at the lower eleva- 
tions south of La Paz. Along the basal slopes of the Victoria Mountains it forms a 
good-sized tree, 7.5 to 9 meters high. A specimen with the long, slender seed pods 
fully ripe was taken between Tres Pachitas and Valle Flojo, December 25. Not 
noted byus north of La Paz. Brandegee records the species from San José del Cabo 
and San Bartolomé. He remarks that the name “ palo de zorilla”’ (skunk tree) seems 
wholly inappropriate, as the tree possesses nothing to suggest such a name. 
Cassia articulata Rose. 
The type of this recently published species was collected by C. A. Purpus near 
San José del Cabo in 1901. A specimen with ripe seed pods was taken by us at about 
600 meters elevation between Miraflores and Rancho San Bernardo in the Victoria 
Mountains. Only a few shrubs 1.8 to 2 meters high were seen. These two records 
give the species a very limited known range in the extreme southern end of the 
Peninsula. 
Cassia purpusi T. 8. Brandeg. 
This species was based on material collected by C. A. Purpus near Calmalli in 1898, 
and by us (in flower and fruit) at Rosarito, 18 miles southeast of San Andrés, Septem- 
ber 25, 1905. Its known range is thus limited to a small area in the central section of 
the Peninsula. At Rosarito it was found growing in a moist place along an arroyo. 
The plant is a handsome shrub. 
Cassia goldmani Rose.* 
While on our way from Mulegé across the mountains to La Purfsima this previously 
unknown species was found in a few places between 450 and 720 meters altitude 
on the steep eastern slope leading up to the backbone of the Peninsula, 5 or 6 miles 
southwest of El Potrero. It forms a large shrub or small tree 3.5 to 5.5 meters high 
and is associated with such southern species as Esenbeckia flava, Antigonon leptopus, 
and Erythrina purpusi. Thespecimens, with ripening pods, were collected October 31, 
Cercidium torreyanum (8S. Wats.) Sarg. PALO VERDE. 
No trees were so nearly omnipresent along our route throughout the greater part of 
the Peninsula as those of the genus Cercidium. They abound in nearly every part 
except the higher slopes of the Sierra del Pinal and San Pedro Martir mountains, the 
Victoria Mountains, and the northwest coast region. But the number of species and 
the boundaries of their respective ranges are not definitely known. Cercidium torrey- 
anum is assumed to range from southeastern California southward through the desert 
region between the Gulf and the high mountains to an undetermined southern limit. 
On the east slope of the San Pedro M&rtir Mountains it ascends along the open bot-
