240 A SYNOPSIS OF THE SPECIES OF DIAPHORANTHEMA. 



Leaves stouter and much more rigidly coriaceous in texture, with 

 the vestiture almost pubescent. 



11. T. myosura, Griseb., in Lorentz PL Argent. Exsic, No. 

 122. Stout produced simple or copiously forked, leafy stems 

 l|-3 in. long. Leaves 12-20 to a fully developed simple leafy 

 stem, subterete from a dilated lanceolate base, spreading, reaching 

 a length of 5-6 inches, rigidly coriaceous in texture, ^-in. in 

 diameter at the top of the dilated clasping base, narrowed gradually 

 from the middle to a subobtuse tip, densely coated throughout 

 with reflexed dirty white short pubescence. Peduncle 1-3-flowered, 

 2-4 in. long, pubescent, with usually a bract about the middle. 

 Bract at the base of the flower pubescent, oblong-lanceolate, acute, 

 ^-| in. long. Sepals obtuse, glabrous, under ^-in. long. Capsule

Andes of Bolivia, on trees, in rocky ground, near Lorata, 

 between San Pedro and Coaconi, at an elevation of about 8000 feet 

 above sea-level, Manclon, 1180 ! Cordoba, Lorentz, 122 ! Habit of 

 recur cata, with very different, stouter, rigidly-coriaceous leaves, and 

 different vestiture. 



12. T. fiisca, Baker, n. sp. Stout, woody, leafy stem, ^ foot long, 

 ^-in. diameter at the base, with several spreading or ascending 

 branches. Dilated base of the leaves deltoid, ^-^ in. broad. Leaves 

 spreading, 1^-2 in. long, subterete. ^-V-i in. broad at the top of 

 the dilated base, distinctly grooved down the face, narrowed from 

 the middle to a subobtuse point, densely coated with spreading, 

 linear, pale-brown scales. Peduncle about an inch long, 

 2-3-flowered, with a large lanceolate bract at the middle. Bracts 

 lanceolate, i in. long. Sepals lanceolate, glabrous, nearly as long 

 as the bract. CaiDsule not seen. 



Obragillo ; a single specimen in Mr. Bentham's herbarium, 

 gathered by the United States Exiiloring Expedition under Captain 

 Wilkes. Well-marked from all the rest by its suffruticose habit 

 and deltoid leaf-bases. 



13. T. Gilliesii, Baker. T. compressa, Gillies MSS., non 

 Bertero. Stems 1-2 in. long, simi)le or forked. Leaves distichous, 

 squarrose, linear, about a dozen to a simple stem, i-2 in. long, 

 ^-in. broad at the clasping base, narrowed gradually from the base 

 to the point, rigidly- coriaceous, deeply channelled down the face,' 

 measuring ^-m. in the lower part from the keel to the margin, 

 densely finely lepidote on both sides all over. Peduncle 1-2- 

 flowered, reaching a length of 4-5 in., sometimes suppressed, 

 sometimes furnished with a small clasping bract at the middle. 

 Bract that clasps the flower oblong, pointed, i-f-in. long. Calyx 

 as long as the bract. Capsule cylindrical, an inch long. 



Foot of the Cordillera of Mendoza, Gillies! Marked at a glance 

 by the distichous arrangement of its stout rigidly coriaceous 

 leaves. 



14. T. undulata, Baker, n. sp. Leafy stems cffispitose, very 

 short, ^-f in. long, all simple. Leaves 12-20 to a stem, ascending, 

 crowded, f-1 in. long, subterete, fi'om a clasping lanceolate base,
