A SYNOPSIS OF THE SPECIES OF DIAPHORANTHEMA. 239 



8. T. erecta, Gillies MSS. Leafy stems rigidly erect, simple 

 or forked, 1^-2 in. long. Leaves about 20 to a simjDle stem, 

 linear-subterete from a dilated lanceolate base, ^-^ in. broad, erect 

 or rather spreading, 1-1^ in. long, one-twelfth of an inch in diameter 

 at the top of the dilated base, prominently ribbed vertically on the 

 back in the lower part, narrowed gradually from the top of the 

 dilated base to a subobtuse point, coated throughout with minute, 

 adpressed, peltate, lepidote scales, with a white rim and a brown 

 centre. Peduncle naked, 1-flowered, stiffly erect, 1-1^ in. long. 

 Bracts and sepals naked, lanceolate, ribbed, ^-m. long. Capsule 

 cylindrical, twice as long as the sepals. 



On trees and bushes at the foot of the Cordillera, near Mendoza, 

 Gillies'. T. rigida, Gillies MSS., is obviously a form of the same 

 species without any peduncle. The species is marked in the group 

 by its stout, crowded, suberect, rigidly-coriaceous, thinly-lepidote 

 leaves, strongly ribbed on the back in the lower portion. 



9. T. recurvata, Linn. ! Schultes fil. ' Syst. Veg.,' vol. vii., 

 part 2, p. 1202. Diaphoranthema recurvata, Beer, Brom., p. 156; 

 T. unifiora, H. B. K. Nov. Gen., i., p. 290; DiapJioranthema 

 uniflora, Beer ; Tillandsia Landbeckii, Philippi, in ' Linnaea,' vol. 

 xxxiii., p. 248. Densely caespitose simple or forked stems 

 1-2 in. long. Leaves 12-15 to a fully- developed simple stem, 

 terete from a dilated, clasiDing, lanceolate base, spreading, 2-3 in. 

 long, ^-hne in diameter at the top of the base, clothed with dense, 

 spreading, persistent, lepidote scales. Peduncle filiform, 1-3- 

 flowered, 2-5-in. long, usually naked, rarely furnished with a bract 

 apart from the flower. Bracts lanceolate, acute, |-|-in. long, 

 more or less hairy. Sepals obtuse, ^-in. long. Capsule |-1 in. 

 long, its valves about one-twelfth of an inch broad. 



This, the type-species of the group, is the most widely-spread 

 of all the Tillandsias, as it extends from Florida and Mexico to 

 Buenos Ayres and Chili, reaching in the Andes an elevation of 

 8000 feet. T. monostachys, Gillies MSS., which grows upon the 

 Cactuses used as fences at Buenos Ayres, is evidently simply a 

 dwarf form of recurvata, with leaves not more than 1-1 i in. 

 long, short peduncles, and generally solitary flowers. There are 

 specimens of the species both in the Linnean and Gronovian 

 herbaria. 



10. T. andicola, Gillies MSS. Leafy stem produced to a 

 length of about 8 inches, flexuose, bearmg about 20 leaves. 

 Leaves rigidly coriaceous, subterete from a clasping, lanceolate 

 base, flexuose, the lower ones spreading, the upper ascending, 1-2 

 in. long, the blade about one-sixteenth of an inch in diameter at 

 the top of the dilated base, narrowed gradually from the middle to 

 a subobtuse point, not perceptibly ribbed vertically on the back in 

 the lower part, the whole lamina thinly coated with very small, 

 fine, narrow, rather spreading, whitish, lepidote scales. Peduncle 

 1-flowered, bractless, lepidote throughout, above an inch long. 

 Bract lanceolate, |-in. long, pilose. Sepals naked, lanceolate, 

 acute, ^-in. long, strongly-ribbed vertically. Capsule not seen. 



Andes of Mendoza, Gillies ! Longer stems than recurvata.
