Passifiora, is doubtless a very distinct genus, with a 

 coloured, bell-shaped Calyx, and fringed, deeply 

 5-cleft, Corolla. I would call it Blepharanthes, to pre- 

 serve an analogy with Trichosanthes. A species of 

 this genus, broughtby Dr. Afzelius from Sierra Leone, 

 flowered, many years since, in Sir Abraham Hume's 

 stove, and I believe is still growing there. Zucca of 

 Commerson likewise appears to be a distinct genus, 

 which cannot be settled for want of the Fruit. 



Ord. 98. UrtiCjE. " Flowers monoecious or dioe- 

 cious, rarely united. Calyx, in every instance, of 

 1 leaf, divided. Corolla none. Barren Flowers with 

 definite Stamens, inserted into the lower part of the 

 Calyx, opposite to it's segments. Fertile Flowers 

 with a single superior Germen. Style either wanting, 

 or 1 or 2, often lateral. Stigmas often 2. Seed 1, 

 inclosed either in a brittle crust, or a tunic, either 

 naked, or covered with the sometimes pulpy Calyx. 

 Embryo straight or incurved, destitute of Albumen. 

 Trees, Shrubs, or Herbs, sometimes milky. Leaves 

 alternate or opposite, generally with Stipulas. Flow- 

 ers either solitary, racemose, or assembled many to- 

 gether on a catkin-like Receptacle, or concealed more 

 or less in a single-leaved common Involucrum. Fruit 

 sometimes many-seeded, from the assemblage of nu- 

 merous Seeds in one aggregate, or confluent, Involu- 

 crum or Receptacle."
