of woody fibre. These latter, being destined to supply the scales, 

 first pursued a course parallel to the axis, and then turned outwards 

 to the bases of the scales.

In relating the history of this plant, it is to be observed, lastly, 

 that some time before the scales began to fall from the axis, a setrof 

 young leaves made their appearance on one side of its base. They 

 were invested with a thick, silky, olive-coloured pubescence. They 

 at first took a horizontal direction, but on the removal of the cone 

 their tendency was upwards. 



Encephalartus horridtts. — A male plant flowered in 1889 at Kin- 

 mel Park, the seat of Lord Dinorben, who presented the cone to the 

 Linnean Society. (Proceedings, p. 9 ; Annals of Nat. Hist. vol. iii. 

 p. 58.) 



A female bore fruit at Chatsworth in 1846, and is now in fruit 

 again. Another female, formerly in the garden of the Horticultural 

 Society at Chiswick and now in Mr. Yates's possession, has twice pro- 

 duced a cone supported by a short peduncle. Among the distinctions, 

 to which allusion has been made already, between the genus Cycas and
