Manual de Plantas de Costa Rica 235 
Tetranema floribundum* (CT); and Ayenia mastatalensis*, Caryodaphnopsis burgeri*, 
Dalbergia frutescens, Eugenia teresae*, Lecythis mesophylla, Meliosma clandestina*, 
Plinia puriscalensis*, Stemmadenia simulans, Ternstroemia multiovulata* , Unonopsis 
theobromifolia*, Vochysia megalophylla, and Williamodendron  glaucophyllum* 
(LCNP). In this last-mentioned park, at least 14 species endemic to Costa Rica are 
known (Acosta, 1998). For more information about the structure and composition of 
this zone, see Acosta (1998), Morales (1998b), and Jiménez M. & Grayum (2002). 
Other localities within the widely circumscribed central Pacific region that have 
generated numerous new records for the country are concentrated in the area directly 
south of San José, from between the Rio Grande de Candelaria and Cerro Caraigres to 
Fila Chonta, Cerro Nara, and the northern part of the Fila Costefia. Some of the new spe- 
cies described from here, the majority endemic to Costa Rica, are Allomarkgrafia insig- 
nis, Chamaedorea binderi*, C. incrustata*, C. piscifolia*, C. rossteniorum, Elaeagia 
glossostipula, Kefersteinia orbicularis, Lacmellea zamorae*, Matisia tinamastiana*, 
Ocotea klepperae*, Ornithocephalus castelfrancoi, Paradrymonia bullata*, Parathesis 
acostensis*, Philodendron dominicalense*, Prestonia hammelii*, and Weberocereus 
frohningiorum*. Some of the country records recently reported from here, most still 
known in Costa Rica only from this region, are: Alfaroa mexicana, Amelanchier den- 
ticulata, Aparisthmium cordatum, Bakeridesia vulcanicola, Calathea coccinea, Catop- 
sis hahnii, Chiangiodendron mexicanum, Cosmos crithmifolius, Donnellsmithia juncea, 
Heliotropium rufipilum, Hintonia lumae- 
ana, Ruyschia cf. pavonii, Sebastiania 
panamensis, Tachia parviflora, Tripogan- 
dra amplexicaulis, and Zeugites pana- 
mensis. Many of these species are widely 
disjunct between Costa Rica and other 
countries. One interesting case is that of 
Chiangiodendron mexicanum (Flacour- 
tiaceae), previously known only from the 
extreme south of the state of Veracruz 
(Mexico), in the area of Uxpanapa. This 
entity had only recently been described as 
anew genus and species in a group of the 
Flacourtiaceae otherwise known only from 
south and Southeast Asia and Australia 
(Wendt, 1988; see also Estrada, 2000, and Sosa et al., 2003). Sporadic recent visits to 
the lower basin of the Rio Palo Seco (opposite Fila Chonta) have even yielded new fam- 
ily records (Canellaceae, Santalaceae) for Costa Rica (see Grayum et al., 1999, 2000a, 
2000b). For more information on the central Pacific region, see Acevedo et al. (2002). 
The southern end of the General Valley and the canyon of the Rio Grande de Térraba 
have also yielded a great many new country records during the last decade, including 
Weberocereus frohningiorum
