74 MISSOURI BOTANICAL GARDEN. 
linear-lanceolate from a broad, deltoid base; end-spine 
slender, terete; marginal fibers few; base of leaf bordered 
with minute, cartilaginous teeth; scape 12 to 15 dm. high, 
slender; bracts very narrow with a broad base; flowers in 
twos or fours, small, 12 mm. long; perianth 8 mm. long; 
filaments inserted in lower part of tube, a little longer than 
perianth ; capsule globular or ovoid, more or less cuspidate, 
9 to 12 mm. long, 9 to 10 mm. broad; seeds dull, 2.5 mm. 
wide. Professor Toumey found well-developed seeds on 
August 20th.— Botany of Mexican Boundary (1858), 214;

Dr. Trelease in Fifth Report of the Garden, page 164, 
speaks of the rediscovery of this interesting plant by 
Professor Toumey in the Pinal Mountains, and makes 
critical notes in comparison. His plate is reproduced for 
this paper by his permission.— Mountains of Arizona, at 
head waters of the Salt and Gila Rivers, in the Pinal 
Mountains, at an elevation of about 7,000 feet ( Professor 
J. W. Toumey), and near Chihuahua, Mexico.— Plate 30. 
Specimens examined: — Original Schott specimens in 
Engelmann, Torrey and National herbaria, from Sierras of 
Pimeria alta, Arizona, July, 1855; J. W. Toumey, July, 
1893; also specimens in Engelmann, Gray and Columbia 
College herbaria from ‘‘dry, porphyritic hills,’’ near 
Chihuahua, found by Mr. C. G. Pringle in fruit, Septem- 
ber 6, 1888. These Mexican specimens have longer and 
slightly narrower leaves, but agreeing with the Toumey 
specimen in being concave on the upper side. Their 
flowers are much longer than those from Arizona. The 
capsules are conically pointed above, and their globular 
form is similar to that of the Schott specimens. 
Professor Toumey writes that A. parviflora propagates 
profusely by numerous suckers. Seeds from his capsules 
have developed into plants 5 cm. high, and from 8 to 10 cm. 
in diameter. Their pretty little rosettes bear dark green 
leaves with reddish-brown end-spines. After loosening
