NO. 2229. FOSSIL PLANTS FROM BOLIVIA— BERRY. 163 



CARPOLITHUS, species No. 5. 



Plate 18, fig. 23. 



A fruit subglobular above, with a long stout peduncle, suggestive 

 of the Lauraceae. Length, about 7 mm. Maximum width, about 

 2.5 mm. 



Cat. No. 35124, U.S.N.M. 



ANTHOLITHUS QUINQUEPARTITA Engelhardt, 



AnihoKthus quinquepartita Engelhardt, Sitz. Naturw. Gesell. Isis in Dresden, 

 1894, Abh. 1, p. 13, pi. 1, fig. 57. 



A small five parted calyx was described under the above name by 

 Engelhardt without any suggestion as to its botanical affinity. No 

 specimens are present in the collections studied by me. In appear- 

 ance it suggests the Anacardiaceae or Celastraceae. 



SPINED STEM. 



Plate 18, fig. 18. 



There are such a variety of unrelated plants in the modem flora of 

 the tropics, including ferns, various monocotyledons and numerous 

 dicotyledons, that possess slender spined stems hke the small frag- 

 ment figured that it is a hopeless task to even pass them in review: 

 As an additional element in the Potosi flora this specimen deserves 

 to be placed on record. 



Cat. No. 35120, U.S.N.M.
