TRELEASE — ILICINE.-E & CELASTRACE^. 35 I 



Mygi}ida is a genus barely separable from the last except in 

 the dehiscence of its fruit. Its few species are peculiar to tropi- 

 cal America. So far as our flora is concerned, it is represented 

 by some of the more characteristic species of the West Indies 

 and adjacent Central America, which have become settled in the 

 sub-tropical Florida region, I have no references concerning 

 their biology. 



Schcefferia includes only our species, one of which belongs to 

 the Texano-Mexican region, and the other to the West Indian re- 

 gion. The small disk and large divided stigma of this genus are 

 quite aberrant in the Order. Nothing appears to have been pub- 

 lished on its biology. 



If, as I believe, Mortotiia Palmeri^ Hemsley, of Mexico, is 

 only a form or variety of M. Greggii^ this genus likewise includes 

 only our species, which belong to the Texano-Mexican region. 

 Nothing has been written on their biology. 



Hippocratea is a tropical genus of wide distribution, including 

 about 60 species, chiefly centering about Brazil. Our single rep- 

 resentative belongs to the West Indies and Central America, and 

 has established itself barely within our limits, like the species of 

 Myginda. Several Tertiary species are described from more 

 northern latitudes. The prehensile twigs of a species of this 

 genus are described by Fritz Midler.* The winged seeds are 

 adapted to dissemination by the wind. Nothing appears to have 

 been written about the pollination of species of the genus. 



SYNOPSIS. 



Tribe I. Celastre^e. — Stamens 4 or 5, inserted on or below the mar- 

 gin of the disk; seed albuminous except in some species of May- 

 tenus. 



* Leaves opposite; fruit dehiscent. — § Euoiiymece. 



I. EuoNYMUS — Flowers seemingly hermaphrodite but really polyga- 

 mo-tricecious, 4- or 5-merous; calyx shallow; filaments very short; 

 anthers didymous, the subglobose cells dehiscing across the top; style 

 short, terminal; ovary immersed in the disk, 3- to 5-celled, with mostly 

 a pair of ascending or pendent ovules in each cell; capsule more or less 

 lobed, coriaceous, colored, with usually a single seed in each cell; seeds 

 enclosed in a scarlet or orange aril.
