PLANT FAMILY: Costaceae
BOTANICAL NAME: Costus laevis maximus form
FORMAL SCIENTIFIC NAME:
STATUS :
CONTINENT: Neotropical
SYNONYMS:


BOTANICAL NOTES:
This form of Costus laevis is characterized by a shorter, truncate ligule and usually has thick short hairs around the ligule. It is a more massive plant than the "skutchii" form at PID7610. The basal ligules (lacking leaves) are glabrous and bulge outward distinctively. The young inflorescence is globular in shape and the bract colors are usually mostly green, and not red or dark purple. This form is found on the Caribbean side of Costa Rica and Panama, and also in the central mountain regions of Costa Rica to the north of Puntarenas province.

I am basing this grouping on the plant form as collected in 1898 by A. Tonduz at Tucurrique in Cartago province along the Rio Reventazón. The plant was originally described as Costus gigantea Kuntze and renamed as Costus maximus Schumann as the epiphet "giganteus" had already been used for an African plant (Costus giganteus Welw. ex Ridl. It may well be that this form is also the form of the Guatemalan plant that was described and named as Costus splendens.

I have been to the Tucurrique area and have seen these plants at the nearby Reserva La Marta and other areas on the Caribbean side (east of the Talamancas of Costa Rica) and Panama. Photos and observations of this form are included on this page. Note that some of these plants from the La Cangréja area in Puriscal (just to the north of Puntarenas) seem to be intermediate between the two forms but I have somewhat arbitrarily grouped them here. All those from Puntarenas are grouped in the skutchii group, PID 7610.

ACCESSION NOTES:
R2247 from Panama, Bocas del Toro, Almirante. Note that this collection has a long, deeply lobed ligule and could be intermediate to the "skutchi" form, but I have included it here due to the light green globular inflorescence that is characteristic of the C. maximus type.

R3035 from Costa Rica, Limon, near the town of Shiroles at about 300 meters.

R3355 from Panama, Colon, Rio Piedra at 60 meters.

R3366 from Costa Rica, Cartago, Finca Guayacan (road Turrialba to Siquires) at 700 meters. This plant closest to the type locality of C. maximus.
