Chamaecostus lanceolatus subsp lanceolatus is distinguished from subsp pulchriflorus by the length of the calyx and bract being about equal.  Here we have (from top to bottom) the calyx with a flower bud, the very small bracteole, and the bract. - Click to see full sized image

PLANT FAMILY: Costaceae
BOTANICAL NAME: Chamaecostus lanceolatus
FORMAL SCIENTIFIC NAME: Chamaecostus lanceolatus (Petersen) C.Specht & D.W.Stev.
STATUS :Accepted
CONTINENT: Neotropical
SYNONYMS:
Costus lanceolatus, Costus phlociflorus,

BOTANICAL NOTES:
This is a beautiful red flowering species and is described in two forms - subspecies lanceolatus and subspecies pulchriflous, distinguished by the shape of the inflorescence and the length of the bracts compared to the calyx. I found this subspecies of C. lanceolatus (subsp. lanceolatus) in Mato Grosso state in Brazil in the Alta Floresta area and at Cristalino. It was quite common there, usually growing in rocky areas. I wrote an article about the Chamaecostus of Cristalino published in the December 2012 issue of the Heliconia Society International quarterly Bulletin.

December 2013 issue of the Heliconia Society International Bulletin, Vol. 19, No. 4

Thiago Andre published results of phylogeny of Chamaecostus.

Chamaecostus lanceolatus is a much sought after plant with its beautiful red flowers. I had only seen a few photos of it on the internet but it is very common in the Alta Floresta area of Brazil. I have prepared a thumbnail sheet with some of my photos of this amazing plant at http://www.gingersrus.com/COSTACEAE/Chamaecostus/lanceolatus/subsp-lanceolatus/

On the internet I saw a photo of a "Costus sp." at the Los Amigos biological station in southern Peru. The plant and inflorescence appeared to be the same as the C. lanceolatus I had seen, but the flower color was orange instead of red. In discussing this with Thiago Andre, he confirmed that the range of this species extends into Amazonian parts of the state of Acre in Brazil and into Peru, but the flower colors tend to be more orange than red.
