glabrous abaxially, sporangia four, stamens of whorl III 1.7 - 2.1 mm long, filament sericeous 
adaxially, red hairs present, sericeous on lower half abaxially, sometimes glabrescent both ad and 
abaxially, anthers 0.8 - 1 mm long, sericeous adaxially, mainly on lower half, red hairs present, 
sporangia four, glands ca. 0.5 mm long, just above filament base, sericeous adaxially, red hairs 
present, staminode | - 1.2 mm long, filament sericeous ad and abaxially, sometimes only towards 
the margins, red hairs present adaxially, head 0.6 - 0.8 mm long, trullate in outline, slightly 
sericeous on base adaxially, sericeous abaxially or glabrescent, hypanthium ca. 0.5 mm deep, 
glabrous or glabrescent outside, densely pubescent inside, mostly red hairs present, sometimes 
only strips of hairs coming down from whorl stamens III and staminode bases, pistil 2.2 - 2.8 
mm long, glabrous, ovary 1.1 - 1.4 mm long, 0.8 - 1.1 mm wide; fruit 15 - 22 mm long, 8 - 12 
mm wide, ellipsoid, cupule 7 - 10 mm long, 6 - 7 mm wide, pedicel 1 - 4.5 mm long, 1.5 - 2 mm 
wide, tepals persistent. 
Flowers from March to August. Fruits ripe in April and May, immature in August. The 
vegetation types where this species grows are temperate mixed forest, riparian forest, deciduous 
forest, cloud forest; between 2150 - 2800 m of altitude. East facing slopes of mountain ranges in 
southern Mexico (Oaxaca and Chiapas) constitute the area of distribution for this species. 
That C. areolatum is really a distinct species from the variable C. triplinerve is still open 
to confirmation. So far, the combined characters of twigs ridged, along with distinct and raised 
minor reticulation on lower leaf surface, work well to separate this species most of the times. 
Sometimes though, specimens that overlap to some extent with C. triplinerve are found, e.g: R. 
Torres 2687, R. Torres 2696, and R. Torres 8455.
