Orver —PALMACEA. 
This noble family of arborescent plants unfortunately con- 
tributes but little towards the permanent decoration of our 
vardens in consequence of none of the species being perfectly 
hardy in our climate. But as some of the more robust species 
are employed in the sub-tropical garden during the Summer 
months, we must devote a little space to their consideration. 
With very few exceptions, the Palms have unbranched stems 
crowned with a tuft of usually very large leaves. The extreme 
forms exhibit two distinct kinds of foliage, though there arv 
species having foliage of a somewhat intermediate character. 
There is the flabelliform or fan-shaped leaf, as in Livisiona 
austrilis, syn. Corypha australis (fig. 221), a handsome 
Australian species with immensely large shining leaves and a 
trunk from 50 to 70 or more feet bigh; and the pinnate or 
feathery leaf, as in the Date Palm, Phiniv dactylifera (fig. 
222), which grows from 60 to 80 feet high, and is extensively 
cultivated in Northern Africa and elsewhere for its edible 
fruit. Before enumerating a few of the hardier species 
suitable for the embellishment of the garden in Summer, we 
will give the principal technical characters. The stems of
