618 WILSON EXPEDITION TO CHINA 



is examined, a perfect agreement in the position and in the number of bracts and 

 bractlets is found. In that species the whole whorl is supported by two bracts; 

 these are followed by a series of four narrow bractlets corresponding to the pro- 

 phylla of the central flowers of the two cjTnes, and alternate with the ovaries 

 follows a second series of six larger and broader bractlets corresponding to the 

 prophylla of the four lateral flowers of the cymes. The only difference is that in 

 Heptacodium the bractlets of the two series are almost alike in size and shape. 

 In either case the inner series ought to consist really of eight bractlets, but the devia^ 

 tion in the number of bractlets is easily explained by the abortion of one pair or the 

 union of two pairs of bractlets caused by the fact that they alternate with the six. 

 ovaries which leaves space for six bractlets only. Abortion or union of bractlets 

 is of very frequent occurrence in Lonicera. 



Only a single ripe fruit was available for examination; the seed was 7.5 mm. long 

 and cylindrical in the lower fourth, which contained theembrj'o; the upper three- 

 fourths were flattened and had the appearance of a wing-like appendage to the lower 

 thick part. This appendage, however, did not consist of the testa alone, but con- 

 tained a narrow layer of albumen, which suggests that the peculiar shape of the 

 seed may be due to the shrinking of the upper part for want of nourishment, the 

 fruit having possibly been gathered before it was fully ripe. 



The generic name is derived from IttA and Kwdna in allusion to the seven- 

 flowered heads of the inflorescence.
