bottom heat for months; and again kept moderately cool for 
as long ; it was kept dry at one time and copiously watered 
at another, but all to no purpose; at last it made a push 
and produced a fine frond, and subsequently a male cone,.- 
» with considerable rapidity. 
The largest specimen now at Kew has a frond five feet in 
diameter, with the individual pinnules four inches long ; its 
graceful, glossy foliage is very ornamental, and the plant is 
remarkably free from the attacks of insects. In some dried 
specimens there is a strong tendency in the leaflets to become 
laciniate at the apex. The ripe fruiting cone is very curious, 
and quite unlike any other Cycadeous fruits which I am 
acquainted with; it is about the size of a human fist, and . 
consists of about twenty broadly ellipsoid nuts, one inch in 
long diameter, adhering in pairs to the shrivelled scales, and 
these to the axis in a very irregular manner, the scales having - 
shrunk so much that the seeds are completely exposed, and 
point in various directions, seldom retaining their original 
position which is inwards or towards the axis. : 
Tn addition to the habitats already known for this plant, 
of Endeavour River, where it was discovered by Allan Cun- 
ningham, and Rockingham Bay, whence Hill sent it to 
England, and where it grows in company with Macrozamia 
Denisonii, Mueller enumerates those of bushy hills near the 
McKay River, and the summit of Mount McAllister ; he 
further observes that it differs from Zncephalartos only in the 
compound leaves, and he reduces Hucephalartos itself to a 
subgenus of Zamia—J. D. H. :
