 corolla of five alternate free^ petals, contorted in prtefloration. The 

 antlroceum is formed of ten stamens with two-celled introrse^ anthers

itiiited among themselves below. Those of the alternipetalous 

 stamens^ are longer than the five others, and their filaments bear out- 

 side a tongue of variable length. The gynfeceiim is superior, formed 

 of an ovary with five oppositipetalous colls, surmovtutcd by a like 

 number of style branches, swollen to a bifid or lacinate stigmati- 

 ferous head at the apex.

' Some or all of them often hear two or 

 several collateral yellow spots near each other 

 at the summit, like the " glands " of caulino 

 leaves, and presenting a strange modification of 

 tissue. I'hcy are perhaps analogous to the 

 anther colls in the .stamen. 



^ The corolla however often falls in one piece, 

 the petals remaining fastened together for a 

 certain distance on account of a peculiarity of 

 their edges similar to that ohserved in the Liiieie. 

 The petals often have the two edges a little un- 

 symmetrical, the edge covering differing slight- 

 ly from that covered, and sometimes differing 

 in colour. The corolla often opens to the sun 

 and closes again afterwards ; it is generally very 

 caducous like that of the Flax. 



'■' When more or less oscillating their face may

■' The pollen is formed of ellipsoidal grains 

 witli tlirce folds, or is ovoid with outer memhrano 

 divided into two semi-hmato hands. (II. JIoiii.. 

 in Ann. Sc. Nat. scr. 2, iii. 335.)
