XLIX. PASSIFLOEACE^l, PASSION FLOWER FAMILY. 



Represented mainly by the Passion flowers described below. 

 In conservatories may be found one or two species of TACSO- 

 NIA, differing from true Passion flowers in having a long tube 

 to the flowers ; also the true Papaw, CARICA PAPAYA. 



1. PASSIFLORA, PASSION FLOWER. (Flower of the Passion; 

 the early Roman Catholic missionaries in South America finding in 

 them symbols of the crucifixion, the crown of thorns in the fringes of 

 the flower, nails in the styles with their capitate stigmas, hammers to 

 drive them in the stamens, cords in the tendrils.) Herbs or woody 

 plants with alternate leaves and conspicuous stipules, climbing by 

 simple axillary tendrils ; the flowers also axillary, usually with 3 bracts 

 underneath, and a joint in the peduncle ; calyx with a very short tube 

 or cup, and 5 divisions which are colored inside like the petals, and 

 often with a claw-like tip ; petals 5 on the throat of the calyx, or some- 

 times none ; within them the conspicuous crown of numerous filaments 

 or rays, forming a double or more compound fringe ; stamens 5, with 

 narrow-oblong versatile anthers, their filaments united in a tube below, 

 sheathing and adhering more or less to the long stalk -which supports 

 the 1-celled ovary ; styles 3 ; stigmas capitate ; fruit berry-like, edible 

 in several species.
