Apex of stamen, terminal form left, basal form right. There is significant difference here, making me think the terminal one is a separate species.

Farther up the road toward Tapala at about 1250 meters we found these... A basal inflorescence forming with appendaged bract forming.

We also found what I would call C. aff. claviger growing in sunny areas along the road. To the left in this photo with the appendaged bracts. To the right is C. zamoranus.

Then even farther down the road to Tapala was this apparent terminal flowering form of C. zamoranus with creamy yellow flowers and very little of the reddish color.
