Apodocephala pauciflora, Baker. 



A large shrub, with the habit of a Vernonia or Eupatorium, 

 with stout terete woody branchlets. Leaves oblong acute,

 brown pubescence beneath, with 10-12 distinct often forking 

 pairs of rather ascending main veins ; petiole above an inch long. 

 Panicle terminal, 6-8 in. long and broad, the woody branches 

 clothed with short brown pubescence. Capitula glomerate in 

 dense congested corymbs at the end of the branchlets, sessile. 

 Involucre ^ in. long ; bracts drab-brown, rigid, the outer grow-
