as in many cruciferis, the capsule elongates after petals and stamens 

 fall. The two short stamens were normal. 



Another flower, in addition to the normal six stamens had two of 

 the petals antheriferous. There was but a very slight attempt at 

 petal bearing. It is worthy of note that the insertion- of these 

 antheriferous petals was much more nearly opposite the glands than 

 usual, indicating that a disturbance of the spiral growth co-existed 

 with the abnormal condition of the petals. 



Three flowers had a third gland. In one flower the third gland 

 was only half the size, but in other respects similar to the others ; 

 in the other two the extra glands were long and hornlike, as if they 

 were partially developed pistils. 



Another flower had three long and three short stamens. Two 

 flowers were found with three series of stamens, each series of two, of 

 different length. In these the upper pair curved inward, touching 

 the stigma by the upper portion, the anthers, however, recurving 

 from the pistil. 



A flower with four glands was another surprise. One of the two 

 normal ones was unusually large and 5-lobed at the apex. The 

 two extra glands are between the shorter pair of filaments. 



Another had the four long filaments colored like the petals, while 

 the filaments of the two short were white and transparent. 



It is well to note that while the insertion of the short stamens is 

 always under the normal glands, the extra glands are between the 

 pairs, indicating that they belong to a distinct cycle from the other 

 two. 



Examining the flower-bud while comparatively young, a unicel- 

 lular transparent hair is found at the apex of each sepal, which is 

 early deciduous, leaving a bulb-like base, which might easily 

 become a " gland " under some morphological change. 



The upper portions of the filaments connive, and might without 

 close examination be regarded a^ united. It may be noted that on 

 the opening of the flower the lower portion of the sepals separate 

 first, leaving the upper portions to connive to the last. In some 

 flowers the sepals remain united to the last, and are monosepalous. 



In a number of plants which had only a few seed pods on them, 

 the anthers were evidently barren. These plants have had these 

 few fertile flowers pollenized by insects. In other plants the four 

 long stamens would be barren, while the two short stamens would 

 have abundant pollen.
