This was found along the road to Briceño at about 1400 meters. The flower is consistent with Costus kuntzei (f/k/a C. laevis) and the ligules consistent with C. leucanthus. I believe it must be a hybrid of those two species. C. kuntzei was found in the area. Only two plants, a short distance apart along the road were seen here. This hybrid is incredibly hairy with dense brown hairs covering all plant parts. Even the corolla was hairy, something unusual in Costus.

Along the road past San Roque we saw this form of the new species Costus antioquiensis which is very close to the form found farther south in Cauca at the Nirvana Reserve. It has a more tightly closed labellum and is not as hairy as the type. The visible parts of the bracts are green.

This is the form of the type for Paul Maas' new species Costus antioquiensis which was collected near here. The species is quite variable in form, especially the indumenta, but the photos taken here are close to the type form.

Costus antioquiensisObserver
selvaderoDescription
Costus sp. 'Lemon Chiffon' was collected in 1974 very near this same place by Tim Plowman and Paul Maas. We saw it several places along the highway, but only here in flower. It may be a form of the new species Costus antioquiensis or could be a separate undescribed species.

Costus spiralisObserver

This is known in Colombia as Costus spiralis but the involcrum of leaves at the base of the inflorescence indicates that it may be closer to Costus weberbaueri which is nearly identical except for having green bracts.

This observation found east of the mountains in Meta, Colombia appears to be the Costus macrostrobilus form that is currently a variety of Costus guanaiensis. We did not see any other populations of this species in the region.

Costus whiskeycolaObserver
selvaderoDescription
This is believed to be a form of a new species that is proposed to be published as Costus whiskeycola - a species first collected by Tim Plowman in southern Colombia, known as Costus "El Whiskey". The form here is identical in every respect to the Plowman type form except that the bracts are not appendaged. It was found to be the dominant Costus species in the undisturbed primary forest areas toward the southern part of the Santa Cruz Reserve.

Not seen in flower here, this appears to be similar to a 1999 collection from the same area of Madre Selva that was cultivated at Fairchild Gardens (992157), thought to be a form of Costus krukovii. The last 3 photos are of the cultivated plant at Fairchild.
