 Pea, Juncus, Anemone, Corydalis, Viola, Stellaria, Astragalus, 

 Cotoneaster, Saxifraga, Sedum, Lonicera, Valeriana, Artemisia, 

 Senecio, Saussurea, Primula, Androsace, Gentiana, Veronica, 

 Pedicularis, Nepeta, Salix and Allium. 



One of the most interesting plants is ArceiUhohium minutis- 

 simiim, a tiny parasite belonging to the Loranthaceae which is 

 able to kill pine trees. The most striking flower is the blue 

 poppy, a Meconopsis. Megacarpea polyandra is a curious cru- 

 cifer with many stamens. The edelweiss, Leontopodium al- 

 pimim, is abundant. Primula reptans is so small that the flower 

 is taller than the whole plant and is much larger than the leaves. 



A number of our common introduced American weeds are 

 apparently indigenous, including mullein, yarrow, Capsella, 

 Poa sp., Dactylis ghmerata, fireweed, Galium aparine, Galinsoga, 

 Plantago sp., Brunella and Leonurus.

A FOSSIL CELTIS FROM COLOMBIA 

 Edward W. Berry 



I am indebted to Dr. W. P. Woodring for the characteristic 

 fossil fruit of an Eocene species of Celtis which is described in 

 the following note. The specimen is of especial interest, not 

 only because it represents the first fossil species of this genus, 

 which is so abundant in the existing flora of South America, 

 that has been found on that continent, but also because, unlike 

 so many similar plant fossils that have come into my hands from 

 South America, the geological age of the material is definitely 

 known. I owe the specimen to the courtesy of the Tropical Oil 

 Company. 



The specimen upon which the present species is based was 

 collected by A. Iddings and R. L. Beckelhymer on the east side 

 of a hill one mile west of Pijaquay, on the trail passing directly 

 over the hill to Don Gabriel, in the Department of Bolivar, 

 Colombia. It came from marine fossiliferous deposits deter- 

 mined by Dr. Woodring, to be of middle Eocene age, that is, 

 about the same age as the Claiborne group of our Gulf Coastal 

 Plain, the Green River formation of the western Interior (Wy-
