YUCCAS IN A CEMETERY, SEWICKLEY. PA. 
YUCCAS. 
There are twenty species of the fine yuccas we illus- 
trate, divided into four sections and distributed from 
Central America through Mexico, northwest and along 
the Rockies to South Dakota, and around the gulf and 
Atlantic States to Maryland. Nearly all the species 
vary considerably, and the specific names mentioned in 
the dictionaries sometimes mount up to between sixty 
and seventy. 
Of tbe hardier kinds (our engraving shows fine ex- 
amples of Y. filamentosa grown by IMr. John Way, 
Jr., of Sewickley, Alleghany Co., Pa.) there are sev- 
eral forms which deserve to be better known, as they 
are very useful over a wide area of country. There 
is Y. filamentosa flaccida, and also a beautiful 
variegated form ; besides in searching through seed- 
ling beds of this species several plants may be selected 
with idiosyncrasies of habit and colouring — some 
dwarf, others robust ; some becoming purple during 
winter, others remaining quite green, some whiter and 
earlier to flower, and in any case admirable for mass- 
ing, but where formality is desired, such as crosses 
planted on cemetery lots, it is best to propagate by 
suckers and root cuttings, from an individual plant. 
Y. filamentosa is wild around the coast lands of the 
South Atlantic and Gulf States. 
Y. angustifolia is a western species found in Mis- 
souri, Kansas and Colorado, north to Iowa and South 
Dakota. It, too, has several forms, 
Y. recurvifolia is a handsome kin^ often spoken of 
as a form of Y. gloriosa, some of whose varieties it 
resembles. It is hardy north to the middle Hudson, at 
least, but often- fails to flower. It, too, has a variegated 
form. J. McP.
