THE TUTSAN TRIBE. 83 



count the species has acquired the name of "the 

 perforated." 



The flowers grow in loose clusters at the tops of 

 the shoots ; their calyx consists of five sepals which 

 are unequal in size, and which overlap each other 

 curiously at the edges when the flowers are very 

 young. To see this arrangement, cut a young flower- 

 bud across, and you will find that the two largest 

 sepals are on the outside of all (Plate V. 2. fig. 1**) j 

 next one of these is a smaller, of which one edge is 

 covered by one of the large sepals, and the other lies 

 upon the edge of a still smaller one within it ; the 

 last is matched by a fifth of the same size as itself, 

 standing on the opposite side of the flower. 



The petals are five, of a bright yellow, and very 

 large for the size of the flower. At the base of the 

 petals, and from below the pistil, arises a great number 

 of stamens of unequal lengths, with very fine yellow 

 filaments, and small roundish anthers ; if you take 

 hold of a few of these stamens with your fingers and 

 pull them, a cluster will separate from the rest {fig . 

 3.) ; and if you will pull the remainder they also will 

 come away in four other parcels ; so that the stamens 

 are really united into five different parcels, although 

 till you began to separate them you did not discover 

 it to be the fact. This is a curious circumstance 

 to which you will find few parallels in other plants. 



The pistil is an oblong body {fig. 4.) terminated by 

 three styles, each of which is tipped with a little 

 stigma. The inside of the ovary contains three cells* 

 in each of which is a multitude of ovules ; to speak
