CONNARACEAE. J. F. Morales (INB). Three genera of this smallish
family are represented in Costa Rica by a total of 12 mostly lianescent spp.,
with six in Rourea, five in Connarus, and one in Cnestidium.
The at least facultatively non-scandent Rourea latifoliolata Standl. & L.
O. Williams is the only sp. indicated as endemic to Costa Rica; however, two spp.
(a Connarus and a Rourea) are provisionally named, and possibly
also endemic. No cultivated or hypothetical spp. are included.
PROTEACEAE. J. F. Morales (INB). This contribution treats four
genera and 11 spp., of which two genera and three spp. (Grevillea banksii
R. Br., G. robusta A. Cunn. ex R. Br., and Macadamia integrifolia
Maiden & Betche) are known only from cultivation. The indigenous component
comprises five spp. of Roupala (two provisionally named) and three of
Panopsis, a total of twice as many native spp. than were accounted for
in William Burger’s 1983 Flora costaricensis treatment (Fieldiana,
Bot. n. s., 13: 8-14). The last-mentioned work included just three spp. of
Roupala and one of Panopsis (and also did not mention
Macadamia). A further difference concerns the name Panopsis
suaveolens (Klotzsch & H. Karst.) Pittier, applied to Costa Rican material
by Burger, but here restricted to a South American entity; in its place, the
name Panopsis costaricensis Standl., listed in synonymy by Burger, is
resurrected, following Edwards & Prance (Kew Bull. 48: 637-662. 1993). Only
the dubiously distinct Roupala loranthoides Meisn. [see The Cutting
Edge 1(4): 4-5, Oct. 1994] is indicated as a Costa Rican endemic, but the two
provisionally named Roupala spp. may also be.
QUIINACEAE. J. F. Morales (INB). This small family,
"optionally" submersible in Ochnaceae [see
The Cutting Edge 10(3): 5-6, Jul. 2003], is represented in Costa Rica by
two of its four genera, but just three spp.: Lacunaria panamensis
(Standl.) Standl., Quiina cruegeriana Griseb. [with Q. colonensis
(D’Arcy) D’Arcy in synonymy], and Q. macrophylla Tul. (with Q.
schippii Standl. in synonymy). None of these is endemic. An aberrant
collection potentially referable to a fourth sp. is included tentatively in
Q. macrophylla. All our spp. are indigenous shrubs or trees of very
wet lowland (< 800 m) forests.
