Nees says the flowers are axillary and solitary in Pofjonospermum ciliare, but spiked 

 in his Schii-ahea spicigera : he has written on one example of Heudelot's ciliaris, on 

 another spicigera, and they look to me one collection. The spikes when young in Pogo- 

 nospermum are dense, but they open out much in fruit ; the bracts show a passage 

 from leaf to bract, and are throughout the spike so very long and leaf-like in this 

 genus that they might bo described as floral leaves. Lindau says the pollen is 

 tubercled ; I find it unusually devoid of rows of tubercles, or even of spots.
