IN FLORIDA 39 
There is a class of vines which adheres to walls, the bark of trees, 
rocks and the like by means of adventive roots, tendrils or tendril- 
like processes which can be used to cover the stems of such trees. 
In the upper part of the state such vines as Tecoma radicans, 
Bignonia capreolata and Euonymus radicans are hardy and cling 
to smooth surfaces. Ficus repens covers walls beautifully and 
it should be hardy over the greater part of the state. The Bou- 
gainvilleas can be made to climb to the tops of the tallest trees 
and so can Bignonia venusia and all are superb ornaments 
in winter. The Solanums, seaforthianum and wendlandi, the 
Argyreias and Antigonons are fine for covering arbors, verandas, 
or trees in the southern part of the state. I have a poultry yard 
fence which was unsightly and I planted a vine of Ipomoea sidi- 
oides at one corner of it several years ago. This has spread over 
perhaps a dozen rods of the fence, has covered the poultry house 
and a quarter of an acre of adjoiningground. Through December 
every year it is covered with white blossoms until it resembles 
huge banks of snow. By counting the flowers on a given space 
and making an estimate of its entire surface I came to the con- 
clusion that it bore a million flowers a day for over a month. I 
have seen a sheet of moonflower covering the entire front of a 
hammock for hundreds of feet, and a single specimen of A gdestes 
clematidea completely hiding a half dozen large trees. There is 
scarcely anything unsightly on one’s place that cannot be covered 
and beautified with vines. 
Florida is infested with a number of pestiferous weeds and 
among the worst of these are the sand burs (Cenchrus spp.) of 
which we have four or five species; Boerhaavia, a branching plant 
with rounded wavy leaves and minute purple flowers followed by 
small burs; Bidens leucantha, a common weed with white flowers 
and flat, two-awned seeds which attach themselves most lovingly 
to every passer-by. All these spread themselves by their seeds 
which fasten on man and beast. They are not indigenous to the 
virgin forest, though they come in soon after cultivation com- 
mences. Their seeds germinate only on or very near the surface 
of the ground and if one will dig a hole in the sand two or three 
inches deep and bury the plant and all its seeds, scraping all that
