fibre-like structures. Probably in this specimen the whole in- 

 florescence is partially expanded, and is not so conical in form 

 as the more completely closed example shown in PL X. Fig. 1.

V. 2129J. PI X. Pig. 3. 



The remains of a fructification similar to but rather smaller 

 than V. 3177 (PI. X. Fig. 1). Occupying the centre is a well- 

 defined hemispherical boss, 8 mm. in diameter, differing from that 

 in PI. X. Pig. \l in its more spherical form; its surface is covered 

 with small punctations. At the base of this boss there appears to 

 be a small projecting rim, and external to this an almost vertical 

 involucre of narrow bracts. Kesting on the inner face of these 

 bracts is a fibrous material, consisting probably of the same 

 slender structures as those seen in V. 3202 (PL X. Fig. 2), and 

 like them being the small interseminal scales, or peduncles, 

 which make up the peripheral portion of the spadix. Compare 

 B. Gibsonianus, Carr. : in that species the central boss is more 

 cushion-like in form. At a distance of about two-thirds from 

 the base the bracts are bent outwards, as shown in the figure.

V. 2129c. PL X. Fig. 5. 



A star-like cluster of broader bracts, closely resembling such 

 a form as Williamsonia (JBladolepis) acuminata, Zig. (= W. Italica, 

 Sap.). 2 The bracts are arranged in a close spiral, and do not 

 form a true whorl. In some there are a number of fine hairs 

 obliquely attached to the margin ; these are shown on the 

 lower margin of the middle left-hand bract in the figure. The 

 hairy margin corresponds with that in Cycadolepis villosa, Sap., 3 

 and our V. 2802, 4 etc. This specimen probably represents a series 

 of bracts which surrounded the base of an inflorescence. Eccles-
