Family CAESALPINIACEAE 

 Genus CYNOMETRA Linnaeus 



CYNOMETRA McGILU, new species 



Plate 1, Figures 8, 9 



Pod rather small, inflated, tardily dehiscent. About half as wide 

 and thick as long, uniformly rounded at both ends. Peduncle scar 

 excentric toward the placental side, which is somewhat flattened and 

 nearly straight; opposite side full and broadly curved in both lateral 

 and terminal profiles. Valves very thick and leathery. Surface 

 prominently corrugated by irregularly impressed grooves bounding 

 rounded more or less warty ridges. Length, 2.7 centimeters; width, 

 1.3 centimeters; thickness, 1.4 centimeters. Named for the collector 

 A. K. McGill. 



This species is based upon the single valve figured. The only 

 recent form which approaches it closely is the genus Cynometra, which 

 comprises about 30 species of shrubs and trees found in all tropical 

 lands. The recent specimens I have seen are drift material from 

 San Miguel Bay in which the pods are about the same size but are 

 considerably wider and the surface rugosities follow a somewhat 

 differerft pattern from that of the fossil. All of the modern species 

 have small leathery pods with thick, papillosely ridged walls. 



The fossil species is lower Miocene in age, and comes from Quebrada 

 Pajuil west of Rio Sinu, Department of Bolivar, Colombia. 



Order GERANIALES 



Family HUMIRIACEAE 



Genus SACCOGLOTTIS Martius 



SACCOGLOTTIS CIPACONENSIS Berry 



Plate 1, Figures 1-5 



Saccogloiiis cipaconensis Berry, Bull. Torrey Bot. Club, vol. 51, p. 64, figs 

 20-22, 1924. 



This species was based upon four specimens from the Guaduas 

 formation at Cipacon, Department of Cundinamarca, and I have 

 since received a large amount of material from the type locality. 



The silicified fruits of Saccoglottis from Belen, Peru, which I referred 

 to this species, I would now separate as they are prevailingly 5-seeded 

 whereas in the Cipacon material of 46 specimens 4 are 5-seeded, 33 

 are 6-seeded, 6 are 7-seeded, and 3 are 8-seeded. 



There is no need to repeat the description of this form but several 

 illustrations from photographs are given to show the range in size 

 and form.
