174 ALTERATION OF POSITION. 
this is recorded by Dr. Montagne’ in the case of a 
moss, Hncamptodon perichetialis, im which, in the in- 
terior of the capsule, in leu of spores numerous minute 
gemme of the same nature as those in the cup of 
Marchantia were seen. 
Formation of flowers on leaves—It is very doubtful 
whether a flower-bud has ever been found actually on 
a leaf. Mere adhesion of the pedicels of the leaf, such 
as happens in ftuseus, in Helwingia, Hrythrochiton 
hypophyllanthus, and a few other plants, 1s, of course, 
not really to be considered in the light of an actual 
growth from the leaf, and it is very doubtful im the 
present state of our knowledge whether the case of the 
Nepaul barley should find a place here, but for con- 
venience sake it is placed in this section, as it 1s un- 
certain at present where it properly belongs. 
This curious plant has been described and figured

outer palea of Nepaul barley Nepaul barley. 
bearing supplementary florets.
