^ 17. T. fasciculata, Sw. Leaves linear-acuminate, subulate at the base, spreading or 

 recurved, convolute, about as long as the stem ; spike compound, compressed : branches 

 3-8, approximate, nearly as large as the central spike, sessile ; bractlets imbricate-disti- 

 chous, ovate-oblong or ovate, pointed, as long as the calyx ; sepals half as long as the corolla,

 mas convolute ; capsule twice as long as the bractlet. — Catesb. Carol. 2. t. 89.- — T. havanensis, 

 Jacq. (Amer. Pict. t. 94) : a scarcely doubtful synonym, but the leaves are narrower at the 

 base, the capsules longer-exserted. T. polystachya, Jacq. [non L., Sw:). Platystachys 

 digitata. Beer. — 1'-2' high; spikes 2"-6" long: bractlets red, variable in size, 6"'-12"'

** Plowers approximate ; internodes elongating between the bracts in fruit. 



18. T. angustifolia, Sw. ! Leaves linear from a subulate base, convolute, curved,

 than the central : bractlets imbricate-distichous, oblong-lanceolate, pointed. Utile exceeding 

 the calyx, in fmit thrice as long as their internodes ; sepals half as long as the corolla : 3 

 united to the middle : lobes blunt ; petals erect ; capsule little longer than the bractlet.-^
