| + | The genus is less allied to Cycas than to Dioon and Encephalartos, from which it is distinguished by the following characters: lvs. pinnate: scales of the female cones peltate, the shield thickened, ascending, usually produced into an erect, acuminate blade. It is to Austral, what Encephalartos is to S. and Cent. Afr., but that genus differs, according to Bentham, in much more rigid habit and very obtuse or truncate cone-scales. It is closely allied to the American Zamia, which differs in its cones and the articulate attachment of the pinnae. —A dozen and more species in Austral., which, like most of the members of this order, make noble foliage plants for private conservatories. They have the trunk and lvs. of cycas, except that the pinnae have no midrib but are more or less distinctly striate, especially on the under side, with several parallel equal veins, the whole lf. occasionally twisted in some species, but not constantly so in any one. The treatment in this account is adapted from Bentham. |
| + | Macrozamias are representative rather than useful subjects, and not frequently seen. They combine poorly in any scheme of plant and flower decoration; but as single specimens, they always attract attention, and in a grouping of similar subjects, or with aloes, agaves and yuccas they make an effective combination. Their culture is easy. Sandy soil, with charcoal, to keep the soil sweet, ordinary greenhouse temperature, plenty of water during the growing season, which corresponds to our summer, and rest in winter, are the essentials. |
