18 safford: a new genus of annonaceae 



the outer in form. Its generic affinities cannot be established 

 owing to the absence of fruit. The following are the species thus 

 far known belonging to the genus Pseudannona.

notes on artabotrys uncinatus 



This plant, which is one of the sources of the perfume called 

 ylangylang, is of East Indian origin, but is now cultivated in 

 many tropical countries for the sake of its fragrant flowers. Unlike 

 the true ylangylang {Canangium odoratum (Lamb.) King) it is 

 a climbing shrub instead of a tree; the connective of its stamens 

 is broadly expanded instead of being produced into a long taper- 

 ing point; and its one-carpelled fruits contain 2 seeds each ar- 

 ranged side-by-side instead of several superimposed in a series. 

 The following is a translation of Lamarck's original description, 

 under the botanical name Anona uncinata, or "corossol with 

 hooks." 



This cdVossol is remarkable for the singular hooks which the- floral 

 peduncles bear, and which almost resemble the stipulary spines of 

 Hugonia [a genus of Linaceae occurring in the tropics of the Eastern 

 Hemisphere, some of the species of which have hooked axillary pedun- 

 cles]. Its branches are woody, terete, glabrous, and somewhat zigzag
