WATER-LILY TRIBE. 



White Water- Lily, the petals gradually change into stamens 

 towards the interior of the flower; those next the calyx are 

 fleshy and contain air-cells, which must contribute towards the 

 buoyancy of the flower. Their sweet scent enhances its beauty. 

 522. The small Order FUMARIACE^, or Fumitory tribe, is 

 chiefly deserving of notice, on account of its containing some 

 British species, of which one is 



among our most common wild plants. $ff(Q $QL /S #S SIB '^ 

 Their flowers are remarkable for yl JL Y*/f*r~\\\ 

 only possessing two sepals in the !A\( 1// \\* * f. 

 calyx, and four petals which are 

 parallel to each other, the outer one 

 having a little cavity or pocket near 

 its base ; they are also remarkable for never completely unfolding, 



the inner petals remaining adher- 

 ent at the top, so as to enclose 

 the anthers and stigma. The 

 stamens are six, and are united 

 into two parcels, whence the family 

 belongs to the Linnaean class DIA- 

 DELPHIA. The ovarium contains 

 but a single cell, being formed by 

 only one carpel, or by the union 

 of two without a partition ; and 

 the ovules, which are sometimes 

 single and sometimes numerous, 

 are attached in a horizontal direc- 

 tion. This order, which is prin- 

 cipally found in the temperate 

 latitudes of the northern hemi- 

 sphere, is characterised by no pro- 

 perties worthy of special notice.
