A NEW SPECIES OF GALIPEA (RUTACEAE) F R O M NICARAGUA AND COSTA RICA JACQUELYN A . KALLUNKI Kallunki, Jacquelyn A. (New York Botanical Garden, Bronx, NY 10458-5126). A new species of Galipea (Rutaceae) from Nicaragua and Costa Rica. Brinonia 40: 241-244. 1988.--Galipea granulosa from Nicaragua and adjacent Costa Rica is described and illustrated and its similarities to G. longiflora are discussed.

Galipea Aublet (Rutaceae) is a neotropical genus of eight to ten species of shrubs or small trees with alternate, trifoliolate or sometimes unifoliolate leaves. It is a member of the neotropical subtribe Cuspariinae, a group of about 22 closely related genera which are not clearly defined. Galipea has been characterized (Elias, 1970; Engler, 1896) by the combination of a five-toothed cupular calyx, a tubular corolla, two fertile stamens and three to five antherless staminodes inserted near the apex of the corolla tube, basally appendaged anthers, and an ovary of five laterally coherent carpels which form a capsular fruit. Many collections made by W. D. Stevens and collaborators during the course of the Flora de Nicaragua project represent a new species of Galipea, which has an apocarpous ovary and fruit.

Galipea granulosa Kallunki, sp. nov. (Fig. 1) Paniculae angustae terminalis ramis floriferis lateralibus fere sessilibus carpellis fructiferis omnino discretis G. longiflorae Krause similis, sed ab ea lobis calycis triangularibus et fete tam longis quam latis (nec lanceolatis et 5-6-plo longioribus quam latis), corollae minoris tubo 1.4-1.9 cm (vs 3.8--4 cm) longo differt.

Tree or shrub 2-12 m; young shoots densely and minutely pubescent, early glabrescent. Leaves alternate, trifoliolate; petiole flattened or canaliculate adaxially, 3.3-20.5 cm long, glabrous; petiolules 0-1 (2) cm long, sometimes remaining minutely pubescent at maturity; leaflets entire, glabrous, chartaceous, terminal ones mostly narrow obovate but ranging from oblanceolate to narrow ovate, apically acuminate with an acute (or rarely blunt) tip, basally short-decurrent or -cuneate, 12.2-34 cm long, 4.3-16 cm wide, with 8-15 secondary veins per side, lateral ones mostly narrow ovate, sometimes elliptic to narrow obovate, apically acuminate, basally usually oblique but sometimes equal and cuneate, 10.5-28.2 cm long, 3.4-11 cm wide, with 5-11 secondary veins per side; venation raised on both surfaces. Inflorescence a narrow, apparently terminal panicle, densely and minutely pubescent throughout; peduncle 3.7-16 cm long, ridged; flowering rachis 8.2--49 cm long with sessile or subsessile cymose lateral branches subtended by lanceolate bracts, these 2.2-3.2 mm long, 0.7-0.8 m m wide, bracts at base of pedicels smaller but otherwise similar; pedicels 2-3 (5) m m in flower, 1.5-7 m m in fruit. Calyx cupulate, 2.3-2.6 mm long with 5 triangular lobes 0.5-0.7 m m long, densely and minutely pubescent without and apically short sericeous within, in fruit persistent, with lobes 1.8-2.5 m m long, 1.4-2.5 mm wide at base. Corolla 5-lobed, densely and minutely pubescent without, white; tube 14.5-19 m m long, 1.3-2 m m wide, with a retrorse shaggy pubescence within except for basal 2.5 mm; lobes imbricate in bud (1 with 2 outer margins, 1 with 2 inner margins, and 3 with 1 outer and 1 inner margin), oblanceolate, round at apex, densely and minutely pubescent within, 8.3-8.5 mm long, 2-2.7 m m wide, innermost slightly narrower than others. Fertile stamens 2, flanking the innermost corolla lobe,

Distribution, habitat, and phenology: Galipea granulosa has been collected in lowland and lower montane rainforests and in pine forests, from sea level to 700 m, in Matagalpa, Rio San Juan, and Zelaya provinces o f Nicaragua and in Alajuela Province of Costa Rico. On the collections examined, flowers are present from August through October and fruit from December to April. Although Galipea has been defined to include species with a syncarpous ovary and resulting capsular fruit, the presence of an apocarpous ovary and fruit in G. granulosa is not discordant. Because some genera of Rutaceae include apocarpous and syncarpous species (Elias, 1970), this feature may not be a reliable generic character. Galipea granulosa is most similar to G. longiflora Krause, known from Bolivia and adjacent Brazil. This latter species, though described from flowering material, also has apocarpous fruits with beaked mericarps (Bejerano s.n., 17 Jun 1964, US). In addition to similar fruit, the two species share narrow paniculate inflorescences with sessile or subsessile lateral flowering branches and a dense, minute pubescence. Galipeagranulosa differs from G. longiflora by the calyx lobes that are triangular and about as long as wide (vs lanceolate and 5-6 times longer than wide) and by the smaller corolla with a tube 14 to 19 mm (vs 38-40 mm) long. The exact nature of the minute, felty pubescence is difficult to discern, especially on the unexpanded shoot, inflorescence rachis, calyx, corolla, and ovary. On the elongated inflorescence rachis, expanded corolla, and fruit, the pubescence appears at 70 x to be composed of lepidote-stellate, stellate, and tufted simple hairs. The species is named after the granular aspect of the pubescence on the mature fruit. According to label information, the common names of G. granulosa are "yape'" (Laguna 4 and 82) and, more commonly, some version of "pata de yanque" (Araquistain 3232, Danin 77-5-15, Laguna 82, Neill 3656, and Ortiz 243).
