5. Moore says that Mo7iechma is characterised by having the spikes in opposite 

 axils, a character not often seen, in the present plant. In Monechma the spikes are 

 not always in opposite axils, while in the present plant they are so sometimes,

Prof. Oliver says this was his t. 129, fig. A, whereas it was t. 129, tig. B. Inside 

 the two large "bracteoles" there is sometimes (as correctly drawn by Prof. Oliver) 

 an extra small bracteole, indicative of an undeveloped cyme.
