S. Moore says that Monechma is characterised by having the spikes in opposite 
axils, a character not often seen in the present plant. In MJonechma the spikes are 
not always in opposite axils, while in the present plant they are so sometimes. 
5. ML. tettense, C. B. Clarke. Leaves elongate. Bracts 
(especially the lower ones) ovate, acuminate; otherwise as J/. Wel-

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.
