MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [ Vol. 8, No. 1 



Ceratostema loranthiflorum Benth. PI. Hartw. 142. 1844. 



Loja: Cerro Villanaco (ca. 7 km west of the city of Loja), 8,000-9,500 ft. 

 elev., Camp E-163, E-164. E-174 (NY only), E-175 (NY only), E-181, E-197.E-674. 



This species has thus far been collected only in the Province of Loja, and 

 even there it has been known from only half a dozen collections. Dr. Camp's new 

 material, therefore, is very welcome as permitting a better understanding of varia- 

 tion within the species. The plants are noted as shrubs from 0.3 to 2 m. high, 

 arising from large subterranean burls. The leaves and flowers are very variable in 

 width; e. g. nos. 175 and 181 have leaves up to 3.5 cm. broad, whereas in other 

 available specimens they hardly exceed 2 cm. in breadth. Dr. Camp notes that the 

 short broad type of leaf is correlated with a broad corolla, while relatively narrow 

 leaves are associated with narrow corollas. No appreciable differences in corolla- 

 length were noted in the various types. Frequently each calyx-lobe bears an in- 

 conspicuous callose gland dorsally near its base.
