374 safpord: classification of rollinia 



that the corolla lobes were erect and incurved. To prevent 

 possible mistakes of this kind the exact locality in which a new 

 species was collected should always be indicated. If this is 

 done incomplete type material may possibly be supplemented by 

 future collections from the same plant or at least from a similar 

 plant growing very near it. 



The present writer has not sufficient material to attempt to 

 monograph the genus Rollinia. In the following notes he has 

 been much aided by herbarium specimens from the Botanical 

 Museum of Copenhagen sent him for study through the kindness 

 of Dr. C. H. Ostenfeld. 



GROUP A 



COROLLA LOBES OBLONG, WIDELY SPREADING AND SLIGHTLY ASCENDING 



OR UPCURVED 



Rollinia dolabripetala (Raddi) St. Hilaire, Fl. Bras. Merid., 1: 29. 1825. 



Annona dolabripetala Raddi, Mem. Soc. Ital. delle Sci. Modena, 

 18:394. 1820. 



Rollinia longifolia St. Hil., loc. cit. 



In this species, the type of the genus Rollinia, the corolla lobes 

 are laterally compressed and shaped like a hatchet or broad-bladed 

 knife (dolabriform), at first ascending, at length broadly spreading. 



Type Locality: Mount Corcovado, near Rio de Janeiro, Brazil. 



Flowering specimens in the United States National Herbarium 

 were collected in the type locality by Messrs. Rose and Russell (No. 

 20311). 



Rollinia mucosa (Jacq.) Baillon, Adansonia, 8: 268. 1868. 



Annona mucosa Jacq. Obs. 16. 1764 (excl. syn. Rumph.). 



The flowers of this species are described as having oblong corolla 

 lobes spreading outward in such a way as "not inaptly to represent 

 a tricorn hat." The areoles of the fruit are gibbous or convex, not 

 papillose or aculeate. The viscous pulp is edible but of poor flavor. 



Type Locality: Martinique. Growing spontaneously in the for- 

 rests and very rarely cultivated; known locally as cachiman morveux. 



This species is described as resembling in habit Annona reticulata 

 L. Specimens in the U. S. National Herbarium, collected by Pere 

 Duss in Martinique, have coarser leaves and larger flowers than Rollinia 

 Sieberi, and the gibbous areoles of the fruit are bounded by raised 

 polygonal outlines.
