persistentibus. Semina in quoque loculo solitaria, ala brevi marginata. — Frutex pubescens, ramosus. Folia 

 opposita subsessilia, oblongo-lanceolata utrinque pubescentia, subintegerrima. Flores longe pedicellati, 

 iorymboso-racemosi, terminates: alubastrum obovoideum, obliquum. Petala purpurea. 



1. D. lopezioides. (Tab. LX.) • 



The immature seeds are flat, compressed ; we have not observed more than one ovule in each cell of the 

 ovarium. This genus connects Lopezia with Hauya.

Hae. Acapulco. — We cannot make out whether the fruit, before being pressed, was reniform, as in others 

 of the genus, or ovoid.

1. Sicyos vitifolius ; caule sulcato subtriquetro pube glanduloso scabriusculo, foliis 

 cordato-subrotundis quinquelobis scabris, lobis latis obtusis subdenticulatis, cirrhis sub- 

 bifidis, floribus masculis subcorymbosis longe pedunculatis, femineis glomeratis breve 

 pedunculatis, fructibus ovatis longe spinuliferis, spinis obscabris, seminibus ovoideis 

 utrinque obtusis. — S. vitifolius. Willd. ? 



The fruit is about a line and a half or two lines long, and the spines about the same length.

We have described the position of the flowers of this plant, from the remains of the peduncles and pedicels ; 

 both flowers and fruit have fallen off. The genus, therefore, is very obscure ; it has more the habit of 

 Tacsunia or Pussifiora than of the Cucurbitacece, but there are no glands on the leaves or petioles, and the 

 cirrhi are lateral.

Hab. Acapulco. — Judging from the description, we do not conceive that Humboldt's plant differs in the 

 smallest degree from that of Cavanilles. In ours, the pedicels are sometimes solitary, sometimes in pairs. 

 The fruit is almost globose, six or seven lines in diameter, supported on a stalk about an inch and a quarter 

 long. The seeds are compressed, oval, acute at both ends, whitish, and deeply filled with wrinkles. It
