PASSIPLORACBiE.

1. M. coccinea Blanco, Fl. Filip. ed. 2 (1845) 45:5. 



(7, 89, 104K Whitford) April, January: (2927 Burden) March-.' (6782 Elmer) 

 November. In forests 70 to 200 in. 



The above specimens are all with fruits only, and accordingly I am unable 

 definitely to determine at this time whether or not Blanco's species is valid, or 

 whether it should be reduced to some Malayan or Asiatic form. The species is 

 rather common and widely distributed in Luzon, in dry thickets and open forests. 

 Following Engler, Modeeea is a synonym of Adenia, hot with the present doubt 

 regarding the validity of Blanco's species, it is for the present retained in 

 Modeooa rather than to make a new combination. 



2. M. triloba Blanco, 1. c 452 non ( ?) Roxb. 



(1757, 2362 Borden) August. January. In forests at about 100 m. The 

 remarks under the preceding species apply also to the present form.

According to Warburg, the Philippine and Eastern Malayan form is a distinct 

 species, Oelomeles mohteeanu W'arb., but this is reduced by Schumann and Lauter- 

 bach 1 to O. eumatra Miq.
