4 New Species of South American Plants 



anthers ovate, acutish, about as long as the filaments. Style 

 about equaling the stamens, stout. Capsule 13 to 15 mm. long. 



Collected by M. Bang, near Cochabamba, Bolivia, without 

 number. Specimen unique. 



Species near T. homostachya Andre. 



Tillandsia attenuata. 



Finely and densely furfuraceous. Leaves from a very short 

 thick caudex, 2.5 to 4 dm. long, 7 or 8 mm. wide,_ regularly 

 attenuate from the base to the filiform summit, light-green, 

 Peduncle (but one seen) 15 cm. long, stoutish, densely clothed 

 with bracts similar to the leaves, some of them exceedmg the 

 inflorescence. Panicle 6 cm. long, the branches to 2.5 cm. long, 

 crowded, erect-spreading, distichous, the flowers imbricated. 

 Floral bracts about i cm. long, broadly ovate, acutish, strongly 

 ribbed, the keel muricate. Flowers apparently shorter than 

 the scales. Dissection material wanting.

 ber 9. No duplicate." (Herbert H. Smith, Colombia, No. 

 2857-) 

 Tillandsia (§ Platystachya) marantoidea. 



Glabrous. Caudex stout, 15. to 20 cm. long, 2.5 cm. thick, 

 densely clothed with fibrous remains of leaf bases. Leaves 

 about 6 dm. long, 10 to 12 mm. wide, long-attenuate at the 

 summit, bright-green, finely many-nerved, dilated at the sheath- 

 ing base. Peduncle about 4 dm. long, bearing about 7 sheathing 

 bracts 6 to 15 cm. long, which taper regularly from the base to 

 the attenuate rigid apex, strictly erect. Rachis about 4.5 dm. 

 long, forming a loose open panicle, the longest branches about 

 I dm. long, the lower successively shorter and distant, the upper 

 successively more approximate, some of them again branched, 

 the flowers about i cm. apart. Bracts 13 to 15 mm. long, the 

 inner a little shorter, obtusish, not keeled, strongly many- 

 nerved. Sepals 13 mm. long, 5 mm. wide, lanceolate, obtuse, 

 lo-nerved, not keeled. Corolla 16 mm. long, the claw 9 mm. 

 long, the limb spatulate, obtuse, 4 mm. broad, lO-nerved, the 

 nerves in pairs. Stamens 3 mm. shorter than the corolla, the 

 anthers 3 mm. long, lanceolate, attached just below the middle 

 to the broad filament. Ovary ovoid, obtuse, 3 mm. long. 

 Style spirally twisted at the base.

Species near T. rubra.
