much, if at all, in form ; they are therefore said to form a 

 perianth. The perianth nearly always consists of six parts, 

 rarely of eight parts (e.g. Herb Paris, Aspidistra), and 

 usually there is a division into three inner and three outer 

 parts. There are usually six stamens, arranged in two series 

 (whorls), outer and inner. The pistil usually consists of a 

 three- chambered ovary with numerous ovules in each chamber, 

 a single style, and a 3-lobed stigma. Note that in Bluebell

and Tulip the perianth-parts are free from each other, whilst 

 in the majority of Liliaceae (Fig. 112) they are carried up as 

 lobes on the margin of a tube, the stamens being inserted on 

 the inner side of the tube. 



Both self- and cross-pollination occur, most of the flowers 

 being adapted for long-tongued insects. In most Liliaceae 

 honey is produced by glandular tissue in the partitions 

 between the chambers of the ovary. In Colchicum honey 

 is secreted on the outer side of the filaments of the stamens, 

 at the bases of their free parts, not in the long perianth- tube. 

 In Tulip and Grarlic there is no honey, but the flowers are 

 visited for pollen. In Herb Paris the dusky colour and fetid 

 smell of the flower attract carrion-loving flies, which alight 

 on the stigma and then crawl over the anthers, becoming 

 dusted with pollen. 



The fruit is either a capsule or a berry, and the seeds are
