§ MARCIDA. 



Plant tufted, 2-3 



cm. high J with 



very 



short 



repeatedly forked branches above the soil. AVhen at rest quite leafless, 

 ^ach branchlet clothed with fibrous sheaths and terminated by a small dead- 

 lookin<f wliitisli fibrous cone 4-7 mm. long and 3-1 mm. thick, from which 

 durint>' the oTowinu^ season in late antumn there first bursts forth a pair of 



O <^ ^ 



widely spreading leaves united only at thei 



r 



very 



base, f) 



mm. long. 



3-3.7 mm. broad and 1^^2 nnn. tin'ck, deltoid-huiceolate, subacute or obtuse, 

 slif>"hLlv convex above, rounded beneath ; from between the bases of tins 

 pair is soon after developed a second pair, which are united into at first a 

 cylindric body with two small erect tooth-like points (representing the free 

 tips of tlie leaves of whicli it is composed) at its apex; this cylindric body 

 is soon followed by the development of a sindlar body at its base from one 

 or both axils of the free leaves ; with age the cylindric bodies become ovoid- 

 conical ; all are smooth and glabrous, not at all papillose, green, with 

 numerous large and conspicuous pellucid dots when held against the light. 

 The free leaves finally shrivel and dry up into brownish or greyish remnants 

 1-2 mm. long, whilst the cone graduailj becomes fibrous and whitish^ and 

 assumes its resting appearance of being dead. AVithin it, however, are 

 formed a pair of free leaves that will appear when the next season's growth 

 takes place. 'Flowers not seen, but evidently developed when the new 

 irrowth commences. Pedicels of young and mature fruit on dried specimens 

 10-12 mm. long, overtopping the growths. Sepals G, about 2-2^ mm^ 

 lon<»', deltoid-ovatOj subobtuse. Capsule 5 mm. in diameter, G-cellcd.
