SEASON'S PICK: Costus guanaiensis Rusby (& others...) -- COSTACEAE
As often, we're not focusing here on anything particularly uncommon, but
since on our recent trip to the Osa Peninsula, we had the luck of finding
this species and several other Costus doing their best to catch the eye,
we couldn't resist. If this one had no name in the trade, I would suggest
“Costus Pink Goldfish.“ This particular plant was growing on
the northern side of the peninsula, not far from Drake bay, and represents
Costus guanaiensis var. macrostrobilus (K. Schum.) Maas. The species
is widespread, known essentially from throughout the tropical Americas.

This and the three other species featured here below exemplify the high
potential as ornamentals in this family.

Costa Rica only from the southern third of the Pacific slope. Voucher Hammel

Costus osae Maas & H. Maas: Endemic to the Golfito region of Costa
Rica, this species was discovered as a result of exploration in the course of

Costus stenophyllus Standl. & L. O. Williams: Another Costa Rican endemic,

the Pacific slope. Voucher: J. Marin 34
