Paspalum undulatum, Poiret. 



North- and South- America. Noticed by C. Mohr as valuable for 

 fodder. A. Gray records it as annual. 



Passiflora alata, Aiton. 



Peru and Brazil. This Passion-flower and all the following (pro- 

 bably with some other species) furnish Granadilla-fruits. All the 

 species here recorded are perennial, some woody and widely climbing'. 



Passiflora coccinea, Aublet. 



From Guiana to the La Plata-States. The fruits are eaten raw or 

 boiled [Hieronymus]. This plant with probably many others of the 

 genus contains a chemical principle of hypnotic value. 



Passiflora coerulea, Linne. 



South-Brazil and Uruguay. One of the hardiest of all Passion- 

 flowers, and with many others well adapted for covering bowers, 

 rockeries and similar structures. Matures its fruit in the open air 

 even at London [Masters]. The Brazilian P. actinia (Hooker) is 

 hardy in Provence [Naudin]. Many of the equatorial species come 

 from mountainous regions, and may thus endure mild temperate 

 climates. 



Passiflora edulis, Sims. 



Southern Brazil. Frost-shy. With P. quadrangularis preferen- 

 tially grown in sub-tropic Eastern Australia. Fruit purple. 



Passiflora filamentosa, Cavanilles. 

 Southern Brazil. 



Passiflora incarnata, Linne". 



North- America, from Virginia and Kentucky southward. The 

 fruits are called May-pops. 



Passiflora laurifolia, Linne. (P. tinifolia, Jussieu.) 



The Water-Lemon. From the West-Indies to Brazil. 



Passiflora lingularis, Jussieu. 



From Mexico to Bolivia. Professor Ernst of Caraccas says, that 

 its fruit is one of the finest anywhere in existence. 



Passiflora lutea, Linne". 



North- America, from Pennsylvania and Illinois southward. With 

 P. coerulea and P. incarnata among the hardiest of the genus. 

 Berries small.
