head with rive follicles, each follicle with twenty seeds.

(9) Barringtonia speciosa, p. 325.— The drying regime is discussed at 



length on p. 294 ; the proportion of parts on pp. 302, 303 ; 

 and the history of the fruit in Note 1 1 (p. 478) and on p. 318. 

 Only one seed is usually matured in this fruit ; but at times 

 (perhaps in 10 per cent.) there are two seeds. In one fruit 

 specially examined the two seeds were lying one on top of the 

 other, the two contiguous sides being flattened together, as if 

 both seeds had been developed in a single loculus. 

 (10) Bignonla, near aquinoctialis, p. 326.— The placental septum is not 

 differentiated in the data given in the table. This is done

These results may be compared with those for Primula veris 

 (p. 500) and Swletenia Mahogani (p. 503), where a placental 

 axis or columella is concerned.

 fruits where the lower joint as well as the upper joint contained 

 a normal mature seed : —
