pubescent above : mature capsule 6 mm. long : seeds rugose. — Collected 

 by Rev. Lucius C. Smith at Cuatro Venados, altitude 2150 m., 27 June, 

 1894, no. 64; by C. G, Pringle on hills above Oaxaca, altitude 1840 m., 

 6 August, 1894, no. 5608, and in the same locality, 15 July, 1897, 

 no. 6711. 



The species is readily distinguished from T. holosericea, Kunth, by the 

 narrower long-attenuate leaves and by the roseate flowers. 



Tradescantia macrophylla. Stems 4 to 6 dm. high, pubescent : 

 leaves lance-attenuate, 15 to 25 cm. long, 3 to 4 cm. broad, pubescent 

 upon either surface, ciliate ; sheaths about 2 cm. long, somewhat in- 

 flated, veiny, more or less pubescent : inflorescence a terminal spar- 

 ingly branched, villous-pubescent panicle, 8 to 22 cm. long ; the lower 

 divisions of the panicle 7 to 10 cm. long: flowers sessile or nearly 

 so, in clusters of 3 to 5 flowers each : calyx glandular-pubescent : sepals 

 navicular, oblong, nearly 5 mm. long, rounded at the apex, 3-nerved, 

 margins scarious : petals equalling or slightly exceeding the calyx, white, 

 streaked with brownish veins, or in the bud pale blue, marcescent : ovary 

 glandular-pubescent above: capsule 5 mm. long: seeds rugose, 3 mm. 

 long. — Collected by C. G. Pringle on bluffs of a barranca near Cuerna- 

 vaca, 26 July, 1896, no. 7224, and in the same locality, altitude 1538 m., 

 21 August, 1897, no. 6695. 



A well marked species, readily recognized by the long leaves, the close 

 inflorescence, and the white or whitish flowers. 



Anthericum platyphyllum. ? T rachyandra echeandioides, 

 Schlecht. Bot. Zeit. iii. 629, not A. echeandioides, Bak. Roots fascicled, 

 fleshy-fibrous, 1 to 2 dm. long : caudex erect, 1 dm. or more high, sur- 

 rounded by a rather dense envelope of brownish fibres, the remnants of 

 earlier leaves: leaves basal, narrowly lance-attenuate, 1.5 to 4 dm. long, 

 12 to 24 mm. broad, pale or livid green, glabrous on either surface with 

 an inconspicuous semi-transparent hirtellous margin : peduncle about 4 

 dm. high, glabrous, terete, unibracteate, branching above into a racemose 

 paniculate glabrous inflorescence, lateral branches of the panicle 3 dm. 

 long : flowers 2 to 4 in the axils of short scarious bracts : pedicels 

 3 to 12 mm. long, much exceeding the bracts, glabrous, jointed just 

 below the middle: perianth yellow, 2 cm. broad; divisions oblong, 

 obtuse, 10 to 12 mm. long, 3-nerved, the inner slightly larger: stamens 

 equal; filaments muricate; anthers oblong-linear, about 3 mm. long: 

 capsule oblong, triangular, 1 cm. long, strongly reticulate-nerved: seeds 

 angulate, black. — Collecterl by C. G. Pringle on dry limestone ledges 

 near Tehuacan, altitude 1540 m., 29 July, 1897, no. 6680.
