the panicle only •1--15" broad, setaceous tipped. Panicle mostly 

 erect with inclined branches, the numerous golden yellow horizontal 

 clusters appearing to be arranged in more or less vertical rows on the 

 erect branches. Peduncle of clusters very shortly hairy or pubescent 

 towards tip. Invol. spkts. staminate -5—75" long, covered with 

 beautiful golden or deep-yellow spreading bristles with tubercled 

 bases. Gl. i spinulosely acuminate. Sessile spkts. -45" with long 

 pungent callus bearded Avith brown hairs, gl. i thinly hairy below, 

 above hispid or scabrid. Awn 3" long. Ped. spkts. -i-'G" long, with 

 long yellow bristles.

Annual or perennial not large grasses with slender compressed 

 many-noded stems usually from a basal persistent tuft of leaves. 

 Leaves narrow or very narrow ; sheaths compressed, keeled, siiorter 

 than the internodes. .Spikelets in clusters resembling those of Anthis- 

 tiria with a whorl of outer involucral male or neuter spikelets dorsally 

 flattened with short pedicels (or long callus) and a very short central 

 internode bearing a central spike of one, rarely 2, sessile spikelets 

 and their pedicelled companions. IXffering however from Authis- 

 tiria in that the whole cluster is articulate below the involucre and the 

 central spike is not articulate on the minute internode but falls 

 together with the involucral spikelets ; pedicelled spkts. separately 

 articulate. Clusters on short peduncles in the axils of spatheoles, 

 leaving a saucer-shaped disc at tip of peduncle on fall of cluster. 

 Spatheoles few to many in the axils of spathes and these sometimes 

 together with branches in the axils of spathes or leaf-sheaths of a 

 lower order, but in general the branching less compound than in 

 Anthistiria. Involucral spikelets Avith 2 or 3 glumes ; i usually 

 strongly nerved ; ii thinner 1-3-nerved ; iii, if present, narrow hyaline ; 

 anthers yellow or purple. Sessile spkt. lanceolar or bottle-shaped 

 in outline ; gl. i narrowly truncate or minutely 2-cuspidate (from the 

 excurrent keel nerves) ; ii keeled Avith the keel lying betAveen the 

 pedicels ; iii hyaline : iv reduced to membranous base (2-ficl in Holei) 

 of its awn. Ped. spkts. usualh' slender, male or neuter. 



The spikelets or clusters are not pung-ent and their dispersal is by the wind.

few present in a)ithephoroides). Nodes of stem not
