21 1. Selaginella IMBRICATA spring. 
Plate 184. Fig. 3. B Upper surfacex4- c Under surface x 4. 
Stems erect, six to nine inches long, wiry and bare below,, 
rising several together but hardly rosulate ; frond deltoid, 
usually but not always widest below, tapering to a point 
which is either normal or long extended. Leaves sparse and 
irregular on the wiry part of the stem, flat and imbricated 
above that, ovate-oblique, subacute, half to one line long, 
firm ; leaves of upper plane smaller and more acute. Spikes 
half inch long, half line wide, four-ranked, square. Bracts 
ovate, keeled, pointed. 
This has long leafless stolons, and Miss Gibbs referring to 
its growth at Victoria Falls says : “ On the top of, and lower 
down the cliff of the lower gorge of the Zambesi River, 
forming dense carpeting masses on the edge of the plateau. 
In drought condition the whole frond is tightly curled up, 
exposing the light under surface of the pinnae,” and a photo- 
graph, unfortunately rather indistinct, is given {Linn. Soc . 
Jour. Bot. 37, 262, 1906, pi. 17) of this plant under a tree. 
Occurs in the Cameroons, Abyssinia, Zambesia and Arabia. 
Rhodesia. — Victoria Falls, 3000 feet (E. E. Galpin, 7054; Eyles, 546; 
Allen, 90; Jas. Sim; Miss Gibbs, 179, etc.).
