which have no trace of embryo. The genus Macrozamia is 
confined to Australia, where it inhabits both the tropical 
and temperate zones, extending to the Swan River settlement 
in the extreme south-west of the continent. Six species are 
cultivated at Kew: 4. spiralis, Frazeri, Preissii, Macleayi, Mac- 
donellii, and Paulo Guilielmi, to none of which does this bear | 
any resemblance at all, nor does it coincide with the characters 
of the two other species, described in Miquel’s monograph 
of the order: IZ. Peroffkyana, and Oldfieldic. 
Drscr. Trunk subspherical, with a truncate base, eight 
inches in diameter. Leaves six to ten inches, forming a very 
contracted crown, diverging below, then suberect, rigid, 
twisted and flexuous, linear, pinnate; petiole deep green, 
smooth but not polished, reddish-brown towards the base, 
where it is slightly and bluntly 2-edged; pinne about fifty 
pairs, opposite and alternate, five to seven inches long, 
one-third inch broad, very narrow linear-lanceolate, acute but 
hardly pungent, base contracted, nearly three-fourths of an 
inch apart in the middle of the rachis, closer above, more 
distant below, the lower not shorter but with a very few 
undeveloped ones forming short spinous processes on the 
petiole; dark green but not shining above, pale, and 
8 to 10-nerved beneath; petiolule bright red, rather swollen, 
not twisted, but obliquely inserted in the rachis by an 
oblong subdecurrent pulvinulus. Male cone on a stout 
smooth peduncle three inches long, glaucous-green, seven 
inches long by nearly two broad, narrow oblong; scales 
cuneate, shortly pedicellate; terminal boss dilated, trans- 
versely rhomboid in front, with a similar central raised area, 
which bears a mucro on the lower scales, and an erect spine 
half an inch long on the upper scales ; pollen-cells globose, 
covering the whole under-surface of the scale. Female cone 
also glaucous-green, on a very much stouter peduncle (one 
inch in diameter) than the male, broadly oblong, when in fruit 
four and a half inches long by three and a half broad, 
scales about sixty, suborbicular with a short stout pedicel ; 
terminal boss transversely oblong, one and a half inches 
across, tumid, with a prominent transverse central ridge 
that gives rise to a triangular mucro in the lower scales, and — 
an erect spine in the upper. Seeds (perfect?) orange-red, 
subglobose, three-quarters of an inch in diameter, contiguous .
