Glands of the Plumbagineae . 235 
Woronin 1 confines his researches chiefly to the leaves of 
Statice monopetala ( Limoniastrum monopetalum ), but touches 
also on 5. latifolia and 5. sareptana. He, as well as Volkens, 
follows De Bary’s interpretation of the glands, and both make 
no mention of Licopoli’s labours. 
Martinet 2 refers to the well-known stalked external glands, 
and also to the minute internal glands, on the calyx of Plum- 
bago ; and Maury 3 describes the development of the former. 
It may be remarked here that Vines 4 is misleading in the 
following statement : — 6 Similar scales [calcium carbonate] 
occur also on the leaves and herbaceous stems of various 
Plumbaginaceous plants. ... In these cases no glands like that 
described [water-gland] are present ; it therefore to be 
concluded that the epidermal cells themselves excrete ‘the 
calcium carbonate.’
