3, figure 13.) It is an interesting little species, with 
dimorphic leaves, the fertile always much taller, and 
erect. Used by florists to give variety in height in 
baskets and fern dishes. Native in Asia. 
Pteris quadriaurita argyraea (Known in trade as P. 
ctrgyraea). (Plate 3, figure 8.) Silver brake. Striped 
brake. 
A very attractively variegated variety which will 
reach three feet or more under greenhouse conditions. 
Not easy for house culture. It is used by florists in 
small sized plants for its color effect in connection with 
plain green ferns. Native in eastern Asia. 
Pteris multifida (P. serrulata, the best known name) 
(Plate 3, figure 9). Spider brake. 
Similar to P. cretica, but with much narrower divisions 
of the leaf. The variety illustrated, cristata, crested 
spider brake, is beautifully tasselled. There are num- 
erous forms, some variegated. Native in Eastern Asia. 
Pteris tremula (Plate 3, figure 14). Australian brake. 
A large species when full-grown, but mainly in small 
sizes. It is easier to grow than P. quadriaurita argyraea. 
The leaves are clear green, divided somewhat after the 
fashion of our wild brake, P. aquilina. Native in Aus- 
tralia. 
Selaginella emmeliana (Plate 3, figure 21, and plate 
4, figure 7). Emmel selaginella. 
The selaginellas are not ferns in a true sense, although 
they are often grouped with ferns, both hortieulturally 
and botanically. The genus includes some of the most 
beautifully colored of all vegetative plant growths, 
some showing various colors with an iridescent sheen. 
S. emmeliana, and its yellow form, aurea, are rather 
common with florists, and will stand house culture if 
the water supply is never neglected. Parched for a day, 
however, they wither and lose their beauty, although they 
will make a good new growth after some time. In the 
illustration (Plate 4, figure 7) what appears to be a leaf 
is really a “frond” in the original meaning of that term,
