and their ideas of its affinities are consequently much at variance. 
According to Jussieu, the "parts taken for petals are nothing but 
inner divisions of the calyx, usually in a colored state, and wanting 
in several species and therefore, in the judgment of this venerable 
botanist, the order is apetalous or monochlamydeous. De Candolle 
adopts the same view of the nature of the floral envelopes as Jussieu ; 
but he nevertheless considers, we think with propriety, the order 
polypetalous. Other botanists consider the outer series of the floral 
envelopes as the calyx, and the inner as the corolla ; the one is 
green and the other colored. The nature of the filamentous appen- 
dages, or rays, as they are called, which proceed from the orifice of 
the tube, and of the membranous or fleshy, entire or lobed, flat or 
plaited annular processes, which lie between the petals and the sta- 
mens, are ambiguous, but are probably abortive stamens. With 
regard to the affinity of Passijlorece, Jussieu, swayed by the opinion 
he entertains of their being apetalous, and De Candolle, who partly 
agrees and partly disagrees with Jussieu in his view of their struc- 
ture, both assign the order a place near Cucurbitacece ; but when we 
consider the stipitate fruit occasionally valvular, the parietal placen- 
tas, the sometimes irregular flowers, the stipulate leaves, and the 
climbing habit of the plants, it is not difficult to admit their affinity 
with CapparidecB and Violariece — the dilated disk of the former of 
which is probably analogous to the innermost of the annular pro- 
cesses of Passiflorece, 
The plants composing Passifloreos, are the produce of South 
America and the West Indies, where the dense forests are filled with 
their numerous species, climbing over shrubs and trees, and bearing 
flowers of the most curious form of striking beauty, and so singular 
in their appearance that many christian traditions have been adapted 
to these singular floral inhabitants of the forests. Its name is from 
passio, passion, and Jios, a flower — resemblance in crown of appen- 
dages to the passion of Christ.
