220 GENERAL BOTANY 



short point, which represents a fifth stamen, which 

 stands on the upper side of the corolla tube, in the 

 flowers of MILLINGTONIA, the Indian Cork tree, of 

 KIGELIA the Sausage-tree, BIGNONIA, SPATHODEA the 

 Flame-tree and many others is also a staminode. 



The corolla of ACHRAS SAPOTA, the Sapodilla, is 

 monopetalous with six or eight lobes. Alternating with 

 these are an equal number of white scales. These 

 also are staminodes. 



In many unisexual flowers, where an ovary is 

 developed, the stamens are represented by staminodes 

 {and where the stamens are developed, the ovary is 

 represented by a pistilode). 



6. The stamens are often slightly connected at 

 the base, but this connexion may extend all the way 

 up the filaments, so that they form together a tube, 

 to the top or sides of which the anthers are attached 

 by their connectives. This is the case, for instance, 

 in KLEINHOVIA one of the STERCULIACE.E, where the 

 -anthers are in five groups of three each, in GUAZUMA 

 where there are in addition five short points (staminodes) 

 between the five groups. In MELIA the Neem, there are 

 ten anthers, sessile or the top of the tube, the connec- 

 tives being extremely short. In HIBISCUS, GOSSYPIUM 

 -and other MALVACEAE, the anthers are very numerous, 

 and attached not merely to the top but along the 

 sides, too, of the tube by long connectives. 



In RICINUS the Castor-oil plant, the filaments are 

 divided (branched) and have an anther at the end 

 of each branch, so that there are more anthers than 

 filaments. In BOMBAX the Silk-Cotton-tree, the fila- 

 ments are joined at the base into five bundles which
