GOLDMAN—PLANT RECORDS OF LOWER CALIFORNIA. 357 
Specimens lacking both fruit and flowers were collected near the Santa Clara Moun- 
tains, October 14. Fruiting specimens were taken a few miles north of Matancita, 
November 15, and between El Pescadero and El Cajén, December 27. Material in 
the U. S. National Herbarium was obtained by Palmer on Carmen Island, November 
1-7, 1890. Brandegee, in describing the species, recorded it from Magdalena Island, 
Margarita Island, and northward to. beyond San Ignacio. 
RHIZOPHORACEAE. Mangrove Family. 
Rhizophora mangle L. MANGROVE. MANGLE. 
The mangrove is abundant along parts of the coast of the Cape District and the 
adjacent islands. It was first seen by us on the east coast between Santa Rosalia 
and San Bruno, and on the west coast near Matancita, Mangrove lagoons of the 
familiar type seen along the coasts of southern Mexico occur on the shores of the bays 
of Magdalena and La Paz and on the islands of Magdalena, Margarita, and Espiritu 
Santo. Brandegee records the species as covering large areas of shallow water along 
the lagoons as far north as San Jorge. It is known to the people as ‘‘mangle.”” A 
specimen in flower was collected at La Paz, February 17. 
COMBRETACEAE. Combretum Family. 
Conocarpus erecta L. 
This tree, widely distributed along the coasts of tropical America, was taken in fruit 
on the west coast of the Cape District near El Pescadero, December 26. It grows 
4.5 to 7.5 meters high with local habitat much like that of Maytenus phyllanthoides, 
but it also thrives on saline soil beyond the reach of the tide. In some low places it 
forms dense shady groves from which other trees are largely excluded. 
ONAGRACEAE. Evening Primrose Family. 
Burragea fruticulosa (Benth.) Donn. Sm. & Rose. 
This species is the type of a new genus recently described by Capt. John Donnell 
Smith and Dr. J. N. Rose. It is made a new genus on account of its very remarkable 
fruit, which is buried in the tissues of the flowering branches. It is a low bushy 
shrub, 30 to 60 cm. high, and grows on the slopes bordering the bay shore of Magdalena 
Island, where it was collected in flower November 24. Brandegee records it as a 
small spreading or decumbent bush 2 or 3 feet high, seen only on Magdalena and 
Margarita islands. 
A second species, Burragea frutescens (Curran) Donn. Sm. & Rose, was collected by 
Rose on the ocean side of Magdalena Island in 1911. This when in flower is one of 
the most handsome shrubs in Lower California, being covered with a mass of pink. 
Xylonagra arborea (Kellogg) Donn. Sm. & Rose. 
Xylonagra, based on Hauya arborea (Kellogg) Curran, was recently described by 
Capt. John Donnell Smith and Dr.J. N. Rose. It is not only very different from true 
Hauya in habit and flowers, but also grows in very different floral zones. Geograph- 
ically Hauya is restricted to Mexico and Guatemala. 
This handsome shrub was discovered by Veatch on Cedros Island, growing in open, 
sterile, rocky, and clayey soils, at an elevation of from 180 to 600 meters. It was 
described and figured as an Oenothera by Kellogg in 1860.1. The flowering season is 
irregular or considerably prolonged, perhaps depending on the occurrence of rain.
