MYRISTICACEJE.

Myristica (Knema) corticosa. 



are nearly free instead of united. In Compsoncura} there are six, 

 erect and verticillate. In Try a,- the central part of the androceum 

 is pear-shaped, with a concave summit surrounded by a circle of 

 short anthers, attached around its outer edge. In the male flowers 

 of M. corticosa 3 (figs. 307, 308), for- 

 merly made the type of a genus 

 Knema* the perianth leaves are 

 thick, and bevelled into a wedge 

 shape internally ; and the andro- 

 ceum, very short in proportion, forms 

 a little column dilated above into a 

 prominent, flattened or concave 

 head. From the edge of this head 

 diverge short rays, each bearing 

 a short oval or rounded anther, 

 whose two cells open by longitudinal 



slits looking .downwards and outwards. Finally in Pyrrhosa* also 

 raised to generic rank by some, the androceum consists of a little 

 ovoid or obovoid elongated mass, the whole of whose surface is 

 divided into a variable number of divisions, each of which is a linear 

 anther, sometimes of extreme delicacy. 



Thus constituted 5 the genus Myristica contains about eighty 

 species, 7 all arborescent or frutescent, with alternate, often distichous 

 penniveined leaves. All have axillary or supra-axillary inflores- 

 cences, sometimes simple sometimes much ramified and formed, 

 especially in the male flowers, of a very large number of flowers.
