Genus ZAMIA. 
Zamia furfuracea.—There are two fine old plants in the Botanic 
Gardens at Cambridge and Chelsea, which are males, and bear cones 
almost every year. Their stems are short and branched. In the 
Botanic Garden at Liverpool is a female, which produced a cone in 
1848. These three plants agree quite as well with Miquel’s de- 
scription of ‘‘ Zamia muricata, var. angustifolia,” as with his descrip- 
tion of Zamia furfuracea. 
Zamia integrifolia.—A fine female plant in the Botanic Garden at 
Cambridge produces a cone every year, and one is now appearing. 
Five or six bulbs grow from the stem, some of them bearing leaves*. 
Genus CERATOZAMIA, 
Ceratozamia mexicana.—A male plant flowered at Chatsworth in 
1847, and another of the same sex at Kew. The cone of the last is 
preserved in the museum. ‘Two fine plants of this species are now 
flowering at Kew, and there are two in the garden at Chiswick, 
also in a flowering state. At Kew and Chiswick these plants 
are called ‘‘ Dipsacozamia.’ In these gardens the plants differ 
so much in the size and form of their leaves, that they may be pre- 
sumed to belong to some of the four new species preserved at Am- 
sterdam, which Miquel describes in the ‘ Tijdschrift voor de Wetten- 
schappen,’ 1847, p. 38-43. The same observation applies to the 
Ceratozamias in the conservatory of Mr. Loddiges at Hackney.
