|  | Hylocereus monacanthus (Lem.) Britton & Rose (Cactaceae) Like most species of Cactaceae (cactus) from non-desert areas, this specimen of Hylocereus monacanthus (F.A.C.

|  | Hylocereus monacanthus (Lem.) Britton & Rose (Cactaceae) Costa Rica has no deserts and most of the ca. 40 species of cacti there grow in very wet areas as epiphytes (on the branches and trunks of trees). This species, Hylocereus monacanthus (Lem.) Britton & Rose, is also an epiphyte, but it grows on the relatively dry Pacific slope. |
|  | Hylocereus costaricensis (Lem.) Britton & Rose (Cactaceae) This is the edible (and delicious!) fruit of Hylocereus costaricensis (F.A.C. Weber) Britton & Rose, which is known locally as pitaya. Lamentably and unaccountably, it is no longer common (or even seen) in Costa Rican markets. |
