This species was described by De Candolle from Mocino and Scsse's drawing, but it lias 

 never been collected since, so far as we can learn. Its large flowers with laciniatc petals must 

 make this a very striking species and it is surprising that it has not been rediscovered. 

 Schumann thought it might be the same as P. nicoyana of Costa Rica, but a study of recent 

 Costa Rican collections indicates that the species are distinct. The measurements given in 

 the description are taken from De Candolle's plate, and may require some modification. 

 Cactus fimbriatus Mocino and Sesse (De Candolle, Prodr. 3 : 475. 1828) was published only as 

 a synonym of this species.

Mr. H. Pittier informs us that this species is common in the open coastal forests along 

 the Pacific side of Costa Rica. The plant illustrated by Mr. Pittier, referred to below, has 

 a long, slender trunk and is very spiny.
