ROSE—-MEXICAN AND CENTRAL AMERICAN PLANTS. 261 
but usually with 1, 2, or rarely 3 sharp spine-like teeth on the upper margin; male 
cones 15 to 20 cm. long, the bracts with recurved ovate tips; female cones ovate, 44 
cm. long by 20 em. broad near the base; bracts very woolly, 10 to 15 cm. long; seeds 
about 4 cm. in diameter. 
Collected by D. T. MacDougal and J. N. Rose, September 7, 1906, in Tomellfn 
Cafion, Oaxaca (Rose 11352, type), and by C. A. Purpus in Sierra Mixteca, Puebla, in 
1908. 
Type U. 8. National Herbarium no. 454142. 
The specimens found by MacDougal and Rose were in a deep canyon 
well shaded by bushes and small trees. Both male and female cones 
were taken and also a living plant. The latter is now growing in the 
conservatory of the New York Botanical Garden, where also are pre- 
served the cones. In 1908 Dr. Purpus collected seeds and bracts. 
GNETACEAE. 
A NEW SPECIES OF EPHEDRA. 
I was much surprised to find an Ephedra on the desert plain about 
Tehuacin, as none had been reported farther south than San Luis 
Potosi. This one is so clearly distinct from those of northern Mexico 
that I do not hesitate to describe it as new. 
Ephedra compacta Rose, sp. nov. 
A low very compact shrub, 30 to 50 em. high with many numerous short spines- 
cent branches, at first light green but becoming very pale; leaves opposite, high-con- 
nate; male flowers not seen; fruit scales in pairs, high-connate, when mature form- 
ing a small red fleshy fruit; seeds 2. 
Collected by J. N. Rose and J. 8S. Rose near Tehuaciin, September, 1906 (no. 11274, 
type), and at same station by Rose and Painter, August and September, 1905 (no. 
10023). 
Type U.S. National Herbarium no. 454055. 
Nearest F. pedunculata Engelm., but lower, of much more compact habit, and with 
paler and less fluted stems. | 
LILIACEAE. 
A NEW SPECIES OF BEAUCARNEA. 
Since publishing my enumeration of the species of Beaucarnea in 
volume 10, page 87, of this publication, an additional species has been 
sent me by Mr. E A. Goldman, of the Biological Survey, Department 
of Agriculture, which is here described: 
Beaucarnea goldmanii Rose, sp. nov. PuaTeE XX, 
Tall slender tree with swollen base; leaves hanging, 80 to 90 cm. long, 3 em. broad 
at the base, 1 to 1.5 em. broad a short distance above the base, tapering toward the 
apex into a long acumination 20 to 30 cm. long, smooth on both surfaces, the margin 
nearly or quite smooth; inflorescence a panicle 30 to 50 cm. long; pedicels 8 to 10 mm- 
long, jointed near the middle; fruit somewhat glaucous, 18 to 20 mm. long, broadly 
3-winged, notched at base and apex. 
Collected by E. A. Goldman at San Vicente, Chiapas, April 26, 1904 (no, 887). 
Type U. S. National Herbarium no. 566461.
