L. glabrous except the margins and nerves which are scabritl beneath. Hooker 

 states that the spathes are spreadino-, whereas in exile they are erect. The 

 specimens do not always show this distinction. 



2. S. exile, Staj)/. Syn. Andropogon exilis, Hochst. 



Very similar to brevifolium but branching much more fastigiate, 

 leaves acuminate or very acute glabrous or sparsely hairy. Spikes 

 i-1'5", joints pubescent and densely silkily villous towards the tips 

 which have a long tooth or lobe each side. Sessile spkt. -IS-- 18" 

 (•25", J.D.H.), subulate-lanceolate. Gl. i coriaceous, dorsally villous, 

 with very slender 2-fid apex ; ii linear-lanceolate, 1 -nerved, cuspidate 

 or with a short awnlet ; iv 2-fid, awn •3--7" long. Pedicelled spkt. 

 subulate silky, gl. i shortly awned.

The plant usually dries red. Upper spathes often aristulate. Spikes often con- 

 cealed among the leaves. 



77. ANDROPOGON, L.^ 



{Andropogon, section Arthrolophis of F.B.I.) 

 Mostly perennial grasses of various habit. Spikelets 2-nate, the 

 sessile and pedicelled differing from one another in sex and more or 

 less heteromorphous, all pairs similar, or if the lowest sessile spkt. 

 male or imperfect then resembling the others. Spikes (spiciform 

 racemes) many- jointed fragile, paired (sometimes digitate and more 

 than two, but not in our area) on terminal peduncles embraced below 

 by a spathe-like leaf (spatheole), frequently 2 or more pairs with their 

 spathes subtended by a common spathe and so on to more composite 

 branching, the whole forming a panicle. Joints and pedicels slender, 

 or stout, clavate or thickened upwards, tips more or less cupular or 

 -auricled. Glumes 4, membranous or somewhat chartaceous or sub- 

 coriaceous. Sessile spkts. gl. i flat or concave or channelled on the 

 back, 2-keeled Avith sharply inflexed margins from the keels, at least 

 from the middle upwards ; ii subequal, cymbiform, keeled upwards, 

 3-1 -nerved, sometimes awned ; iii hyaline, 2-nerved, usually ciliate, 

 empty ; iv small h3^aline 2-fid or 2-dentate with an interposed awn, 

 sometimes reduced to the awn, palea small or 0. Lodicules glabrous. 

 Grain narrowly lanceolate to oblong, subterete to plano-convex. 



* This is only part of Li»iicBiis's Andropogon and a very small part of the Andropogon 

 ■ot the F.B.I, and of Hackel'a monograph. Following Br. Stapf {FL Trop. Africa, 

 etc.). the various sub-genera of llackel have been restored to generic rank. These 

 are ISchizachyrium, Diectomit, Ilypogynium, Amphilophis, Sorghum, Vetioeria, Chrt/so- 

 pogon, Dicuntkium, Cymbopogon, Heteropogon and Pseudanthistiria, in addition to a 

 new genus Capillidium.
