238 A SYNOPSIS OF THE SPECIES OF DIAPHORANTHEMA. 



species, with more densely lepidote leaves, and a slender peduncle 

 above an incli long. 



5. T. rectangula, Baker. T. propinqua var. rectamjula, Griseb. 

 in Lorentz PL Argent. Exsic, No. 126-127. Leafy stems simple 

 or forked, about an inch long. Leaves about a dozen to a fully- 

 develoi^ed simple stem, half-an-inch long, linear- subulate from a 

 clasping lanceolate base, sj)reading, half-a-line broad where they 

 leave the stem, narrowed gradually from the base to the point, 

 deeply channelled on the lower part of the face, thinly lepidote all 

 over, with one deep lateral • groove on each side in the lower half. 

 Peduncle filiform, terminal, 1 -flowered, about an inch long, with 

 sometimes a bract at the middle. Bract that clasps the flower 

 oblong, ^-in. long. Calyx ^-in. long ; sepals obtuse. Capsules 

 half-an-inch long ; valves a line broad. 



Argentine territory at Cordoba, Lorentz, 126 ! 127 ! Midway 

 between propinqua and rigida. 



6. T. capillaris, Ruiz & Pavon, ' Fl. Peruv.,' vol. iii., p. 42, t. 271, 

 fig. c. Diaphoranthema capillaris, Beer Brom., p. 153. Leafy 

 stems 2-3 in. long. Leaves about 20 to a fully-developed simple 

 stem, subterete from a clasping lanceolate base, about an inch 

 long, one-twelfth of an inch in diameter above the base, ascending, 

 not hau'-like at the tip, densely clothed with loose spreading, pale- 

 brown lanceolate, lepidote scales. Peduncles 1-2-flowei'^d, filiform, 

 2-3 in. long. Bract glossy, lanceolate, ^-in. long, tightly clasping 

 the calyx. Sepals lanceolate, naked, ^-in. long. Capsule cylin- 

 drical, under an inch long, its valves half-a-line broad. 



Andes of Peru, Pavon! The above description is taken from 

 Pavon's copious type- specimens at the British Museum. 1 cannot 

 separate fi-om this specifically T. viresceyis, Euiz & Pavon, 'Fl. 

 Peruv.,' iii., jd. 43, t. 270, fig. 5 {piaphoranthema virescens. Beer), 

 of which there are no type- specimens in the Museum herbarium. 

 To the same species, I think, belong T. incana, Gillies MSS., from 

 trees and bushes at the foot of the Cordillera of Mendoza, and a 

 plant gathered by Mandon (No. 1178) in the temperate region of 

 the Andes of Bolivia, at an elevation of 2700 metres. T. capillaris 

 is about midway betw^een recurvata and propinqua, differing from 

 the former by its shorter, stouter, ascending, more densely lepidote 

 leaves. 



7. T. retorta, Griseb., in Lorentz PL Argent. Exsic, No. 125; 

 T. ccBspitosa, Gillies MSS., non Leconte. Stems 1-2 inches long, 

 simple or forked, bearing about a dozen squarrose rigidly coriaceous 

 leaves, which are about an inch long, clasping the stem by a 

 dilated lanceolate base, |^-line in diameter above the base, narrowed 

 gradually to a fine point, clothed throughout with rather spreading, 

 minute, lepidote scales. Peduncle none. Bracts and sepals lan- 

 ceolate, acute, ^-in. long. Capsule above an inch long, with valves 

 ^-in. broad. 



Mendoza, Gillies! Qoxdioha,, Lorentz, 12b \ Hd^hii oi recurvata, 

 from which it differs by its shorter, stouter, much more rigidly- 

 coriaceous leaves, with a thinner coating of scales, and by its 

 sessile flower and very large capsules.
