I.—An Analysis of the Vegetative Organs of Selaginella grandis Moore, together with some Observations on Abnormalities and Experimental Results

Abstract

Selaginella grandis, a native of Borneo but now widely grown in Botanic Gardens, was first described by Moore (12). It presents a number of points of considerable morphological interest which have been briefly described by various writers including Goebel (6, 7, 8), Harvey-Gibson (9, 10), Seward (13), Uphof (16), and Worsdell (18). So far as I am aware, however, no full account of the morphology of this species has hitherto been published. My attention was drawn by Professor Drummond to certain abnormal developments exhibited by the plants growing in the Botanic Garden of Glasgow, and, in an endeavour to interpret these, I was led to investigate the normal morphology of this species. Accordingly, in this memoir, the normal morphology will first be described, after which the variations from the normal and certain experimental results will be considered.
