SEASON'S PICK: Bakeridesia vulcanicola (Standl.) D.M. Bates (plus various other Malvaceae)
This Season's Pick is dedicated to Paul A. Fryxell, contributor for the Manual
Malvaceae treatment (as well as for many other projects at MO), our long-time collaborator,
and excellent correspondent. Thanks Paul, for all your help
Although one of us has stated something on the order of "Malvaceae are all a
bunch of bloody, nondescript weeds!" others, on closer look even at the most
nondescript of them, would beg to differ. Bakeridesia [see
The Cutting Edge 3(2), Apr. 1996], among the most "descript" of plants
one could imagine , is a case in point and, flowering profusely since the end of
December, wins this Season's Pick, hands down. When we first reported the Costa
Rican Bakeridesia as one of Francisco Morales' many
extremely interesting discoveries from his favorite region of Acosta, we didn't
yet know what sp. was involved. Long since then, Paul Fryxell identified it as
B. vulcanicola, known otherwise from Guatemala, Honduras and El Salvador.
Its large (ca. 10 cm in diameter), extremely showy flowers are rivaled among Costa
Rican native Malvaceae only by spp. of Wercklea. The particular plant of
these photos (vouchered by Hammel 23552) is from a cutting brought home
and nurtured by Hammel in Santa Ana, then transplanted to his new digs in San Isidro
de Heredia, where it really took hold. The plant apparently roots easily from cuttings
and would seem to have high potential as an ornamental, if it's not already in the
trade.
While we're on Malvaceae, here are a few more photos of native Costa Rican spp.,
including other showy ones as well as some more humble...for readers to make their
own judgment. The flowers of all these (except for the larger Malvaviscus
and Pavonia) are within the range ca. 1--3 cm in diameter. All photos for
this Season's Pick are by Hammel.
