186 FAMILIES OF FLOWERING PLANTS 
ovary l-celled, stalked, with 3 styles; fruit 1-celled, either a dry or 
pulpy capsule, The flower of Passiflora is peculiar in having the fila- 
mentous processes disposed in a ring within the petals, so that they 
appear likestamens. This is shown in Fig. 165, and is called the crown 
or corona. 
Most of the species of Passion-flower are natives of South America; 
a few reach our southern borders, and two (P. lutea and P. incarnata) 
extend as far north as Washington. The latter species is an extremely 
abundant weed in the South, where it is known as “may-pops,” from 
the yellow, edible fruit. Many species are in cultivation in our gardens.

The name Passion-flower has been given to the plant on account of 
the symbolic numbers which its various parts exhibit; “thus the three 
nails—two for the hands, one for the feet—are represented by the stig- 
mas; the five anthers indicate the five wounds; the rays of glory, or, 
some say, the crown of thorns, are represented by the rays of the ‘co- 
rona;’ the ten parts of the perianth represent the Apostles, two of them 
absent—Peter who denied, and Judas who betrayed our Lord; and the 
wicked hands of His persecutors are seen in the digitate leaves of the 
plant, and the scourges in the tendrils.”—( Treasury of Botany.)
