68 NATURAL HISTORY OF PLANTS. 
have the mass of carpels spirally twisted (fig. 96), whence the name 
Spirocarpæa They are trees or shrubs, generally covered in 
all parts by stellate or ramose hairs. The leaves are alternate, 
and the axillary flowers are solitary or disposed in small cymes ; 
the pedicels are often furnished with two stipuliform bracts. 
By the side of this genus are placed the five following :— 
Kleinhovia, of which we only know one Asiatic* species, has the 
same androceum as /He/licteres, supported by a long column, at the 
apex of which the gynæceum is planted; but this has an ovary 
with five pluriovulate cells, and the fruit is a membranous vesiculate 
loculicidal capsule. 
Pterospermum (fig. 97) has a much shorter stem, supporting the 
gynæceum and androceum; the former has also a quinquelocular 
ovary. As to the stamens, they have elon- 
gated monadelphous, or unequally polyadel- 
phous filaments, and cells also elongated. A 
dozen species of this genus are known,’ 
being trees or shrubs of tropical Asia, with 
leaves frequently unsymmetrical, and axil- 
lary flowers solitary or few. The fruit is a 
loculicidal coriaceous or woody capsule, with 
winged seeds, 
In Zriolæna; of which the type of a par- 
ticular tribe? has been made, the common 
support of the androceum and gynæceum is much shorter, some- 
Pierospermum suberosum.
