504 LXIII, PASSIFLOREE (MASTERS). 
or more rows of threads scales or rings emerging from the flower-tube. 
Stamens 5 or sometimes ©, distinct monadelphous or polyadelphous, 
hypogynous and sessile or raised with the pistil on a stalk or gyno- 
phore, or perigynous and springing from the tube of the flower ; fertile 
stamens opposite to the sepals; staminodes (when present) opposite to 
the petals if in a single series; anthers 2-lobed, basifixed introrse, or 
dorsifixed versatile, extrorse; dehiscence longitudinal; _pollen-cells 
globose, reticulated. Ovary free, 1-celled, with 3 parietal placentas; 
ovules numerous, funiculate, anatropal ; styles 3, consolidated or sepa- 
rate; stigmas separate (except in Barteria), large, capitate, reniform. 
Fruit baccate, indehiscent or capsular, loculicidally 3-valved. Seeds 
compressed, with a hard pitted testa, surrounded by a pulpy arillus 
derived from the expansion of the funicle. Albumen fleshy ; embryo 
large, straight, erect; cotyledons flat, foliaceous; radicle directed 
towards the hilum.—Herbs undershrubs or trees, the majority (in 
Africa) of erect habit, elsewhere for the most part climbers. Leaves 
alternate, stalked, pentastichous, simple or lobed, often with glandular 
leaf-stalks. Stipules leafy or minute and deciduous. Tendrils axillary, 
springing from the same axil as the flower-stalks. Inflorescence various - 
- but essentially definite. Bracts small, scattered or rather large, folia- 
ceous and involucrate. 
A rather large Order (as above defined), the members of which are almost exclusively 
tropical or subtropical in their distribution, and found in both hemispheres. The majo 
rity of the species are American, and belong to one or two genera. The African forms, 
as will be seen, are included in several genera, but the species are not numerous. e 
arrangement here adopted is that of the Genera Plantarum, but it is questionable 
whether it would not be a preferable arrangement to exclude from Passiflorew proper 
the tribes Modeccew, Achariew, and Papayacee, and to constitute them into a separate 
Family intermediate between Passifloree and Cucurbitacee. True Passifloree seem to 
have closer relations to the Turneracece, Samydacee, and even Violacce, than to 
Cucurbitacee.
