NATURAL HIS TOBY OF FLANTS. 



have the mass of carpels spirally twisted (fig. 9G), whence the name 

 Spirocarpaa. 1 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 : — 

 Klevihovia,- of which we only know one Asiatic 3 species, has the 

 same androceum as Helicleres, supported by a long column, at the 

 apex of which the gynseceum is planted ; but this has an ovary 

 with five pluriovulate cells, and the fruit is a membranous vesiculate 

 loculicidal capsule. 



Pterospermum (fig. 97) 4 has a much shorter stem, supporting the 

 gynaBceum 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, 5 

 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 Eriolcena? of which the type of a par- 

 tic alar tribe 7 has been made, the common 

 support of the androceum and gynseceum is much shorter, some- 



Pterospermum snberosum.
