STANDLEY TKEES AND SHRUBS OF MEXICO. 119 



A close ally of the " zapupe " and especially the " Tequila mezcal " species ; 

 cultivated for its fiber in the Philippines as " maguey " or " Manila aloe," and 

 in India where it is the source of " Bombay hemp " or " Bombay aloe fiber." 



Apparently one of the west-Mexican allies of A. tequiJana, perhaps early 

 taken for its fiber to the Philippines and thence to India, from the Acapulco 

 region. 



28. Agave tequilana Weber, Bull. Mus. Hist. Nat. 8: 220. 1902. 

 Jalisco ; type from about Tequila. 



Shortly caulescent ; leaves rather light bluish green and persistently glau- 

 cous, thin and nearly flat, 8 to 10 cm. wide, 125 cm. long or more, with red- 

 brown or purple-brown spine 3 to 4 mm. wide and 15 to 20 mm. long, and trian- 

 gular upcurved reddish teeth 10 to 15 mm. apart and 3 to 4 mm. long, the 

 intervening whitish margin slightly hollowed. " Mezcal azul " or " chino azul." 



The common source of the distilled liquor, " mezcal de Tequila." A number 

 of related forms are found in cultivation with this typical " azul." These, 

 probably all specifically separable as with the " zapupe " complex, to which 

 tliey are related, are known as " mano larga," " bermejo," " chato," " chino 

 bermejo," " zapalote," " pie de mula " or " pato de mula," and " seguin " or 

 " zi.guln."

 cave, 15 cm. wide, 175 to 200 cm. long, with dark red-brown, conical or acu- 

 minately tapered spine 4 to 7 mm. wide and 10 to 15 or 20 mm. long, and 

 sharply upcurvetl or flexed, triangular teeth on broad bases, 15 to 20 or 35 mm. 

 apart and 5 to 10 mm. long, the intervening margin nearly straight ; inflorescence 

 ample, panicled ; flowers unknown ; capsules broadly oblong, 25 mm. broad and 

 45 mm. long, accompanied by bulbils.

 Ufera Schott, in sched.), " chucum-ci," " citam-ci " (which is A. mmima D'Utra,
