TERTIARY FLORA OF CHILE 95 



and the Antilles, are types often referred to the allied genus 

 Fagara. The genus Ticorea, a small existing genus of 

 Guiana is represented by a species that is named in allusion 

 to its resemblance to the existing Ticorea fcetida Aublet. 

 The material referred to Pilocarpus is not extensive but 

 shows characteristic venation features. The present species 

 is close to the existing Pilocarpus pauciftorus of Brazil, 

 and a second fossil species occurs in the Pliocene of Bolivia. 

 The genus contains about 15 existing species of shrubs and 

 small trees with even pinnate leaves confined to tropical 

 South America and mainly Brazilian. So far as I know it 

 does not occur in the montana country of Peru and Bolivia at 

 the present time, although it is found in the Pliocene of the 

 latter country. 



The genus Erythrochiton comprises a few existing species 

 of small trees ranging from southern Mexico through eastern 

 Peru and Bolivia to southern Brazil. The fossil species, 

 which is represented by a small amount of characteristic 

 material, is close to the existing Erythrochiton brasiliense 

 Nees and Martius, which is a common form in eastern 

 Bolivia, 



The Meliacese is represented by two species of Moschoxy- 

 lum, a genus sometimes made a subgenus of Trichilia, with 

 about 60 existing species of the tropics of America and 

 Africa, chiefly the former. The fossil species are compared 

 with the existing Moschyxlum swartsii Jussieu and M. hir- 

 tum Sowerby of the Antilles and northern South America.. 



The family Vochysiaceae is exclusively South American 

 and tropical with slightly over 100 existing species. Engel- 

 hardt has referred a somewhat inconclusive form from Chile 

 to Vochysia, comparing it with the existing Vochysia ellip- 

 tica Martius. The genus has about 55 modern species of 

 shrubs or trees with coriaceous leaves, and its center -of 

 occurrence is in the Amazon Valley. 



The family Euphorbiacese is represented by three genera 

 each with a single species. The first Omphalea ficiformis
