Barry Langridge 05/23. Flowering in our Melbourne garden January 2021, ex Europe (J.Laut?) with thanks to Peter Tristram.
Peter Tristram ... "Love those habitat pics! I expected it to be more an open grassy type grower so nice to see it in a variety of niches. It's a lovely and unusual species, tough as nails too."

PHENOLOGY: Flowering plants have been collected only during August.

DISTRIBUTION AND HABITAT: Known from Costa Rica and a few recent collections from Cerro Jefe in Panama. Collected between 900-1400 m in premontane rain forest life zone possibly extending slightly into the premontane wet forest life zone.
DISCUSSION: Vriesea capitata remains a poorly collected taxon. In locations where I have collected this species, I have never seen more than one or two individuals in flower or fruit. It is characterized by its rigidly coriaceous leaves in a subascending to suberect rosette, subcoriaceous primary bracts which are divergent to subspreading at anthesis, and its subcapitate inflorescence. The inflorescence of V. capitata is often totally covered with a gelatinous exudate. The developing floral buds are immersed in this gelatinous matrix until anthesis, at which time the white, campanulate nocturnal flowers emerge. When the atmospheric humidity is low, this exudate will dry on the flower buds and inhibit anthesis.
Vriesea capitata is most closely related to V. bracteosa and the characters which distinguish these taxa are discussed under the latter species.

pedicels 7-10 mm long;
sepals 2.2-3 cm long, smooth, coriaceous, glabrous;

In view of the great similarity between Vriesea pectinata and V. chiapensis and the variable character which distinguishes them, scape bracts shorter than the internodes vs. bracts of scape slightly more long that the internodes, are considered both under the same species.
