Season's Pick | Annotate your copy
The main feature of this season's pick is the rare Ipomoea clavata (G. Don)
Ooststr. ex J. F. Macbr. (Convolvulaceae), but we also want to focus on the
Parque Nacional Diriá (Península de Nicoya), with a pictorial overview
of this and some of the other unusual species or country records that we have
discovered from the area in recent years. Here are just a few that were flowering
this last season.
Ipomoea clavata is a widespread species (Mexico to El Salvador, Nicaragua,
Costa Rica, Colombia to Perú) that was previously known from just a few
collections in Costa Rica, gathered over 80 years ago by Alberto Brenes from Carrillos
de Poás in the Central Valley. This pink flowered version with deep red
markings in the bottom of the tube is perhaps taxonomically distinct from the
blue-flowered version collected by Brenes. Vouchered by Hammel & Pérez
Left: Ipomoea muricata (L.) Jacq., likewise had not been
collected in Costa Rica for many years, this one last vouchered from Parque Nacional
Santa Rosa in 1978 (Liesner 4251, MO). We rediscovered fragrant
night-flowering species just last November at P. N. Diriá. Vouchered by
Hammel & Pérez 24992, INB.
Right: Ipomoea suaveolens (M. Martens & Galeotti) Hemsl.
This one, a new record for the country (previously known from Mexico, Guatemela and
El Salvador), is vouchered by Hammel & Pérez 24994, INB.
Doyerea emetocathartica Grosourdy (Cucurbitaceae), was reported new for
the country in these pages last July (
Volume XV, Number 3, July 2008). Left: Hammel & Pérez 24997, INB. Right:

And finally (for now) Tridax platyphylla B. L. Rob. (Asteraceae) was first
collected in the Diriá area by Manual collaborator Alex
Rodríguez (INB) and then a first for the country (see
Number 4, October 2001). We saw it ourselves in November of last year.

Numerous other new records have been recorded from this interesting and
little-explored area in and around the Diriá National Park, which includes
close to, if not the, highest peaks on the Nicoya Peninsula (Cerros Brujo and
Vista al Mar, ca. 930 & 940 m, respectively).
