Two new species of Alstroemeria (A1- stroemeriaceae) from the Brazilian savannas are described: A. stenophylla M. C. Assis, which is characterized by its narrow linear-lanceolate leaves, concentrated on the distal region of the vegetative stem, and for its ruby-spotted inner te- pals, close to A. gardneri Baker and A. plantagi- nea Martius ex Schultes & Schultes f.; and A. tom- bolatoana M. C. Assis, which may be recognized by its coriaceous leaves, outer tepals oblong-spat- ulate, without patterning, but the inner tepals spatulate and ruby-maculate, sympatric with A. gardneri. Descriptions, comments, and illustra- tions are presented. Key words: Alstroemeria, Alstroemeriaceae, Brazil, savannas. Alstroemeria L. is represented by around 90 spe- cies widespread in South America, ranging from Venezuela (3° North) to Tierra del Fuego, Argen- tina (53° South), with two main centers of distri- bution, one in Chile (extending into Peru, Bolivia, and Argentina) and the second throughout Brazil, Paraguay, and Argentina (Bayer, 1987; Aker & Healy, 1990). In Brazil the genus comprises 38 species distributed in the eastern regions of the country. These species occur in different habitats: forest, savanna7 high fields, marsh, "campos ru- pestres," and "caatinga," from a height of 300 m above sea level in the Amazon up to 2300 m above sea level at Serra do Itatiaia. Most species have a restricted distribution (Assis,2001, 2002). The re- cent taxonomic revisions of the group for Brazil (Assis, 2001), Argentina (Sanso, 1996), and Chile (Bayer, 1987) have improved the basic knowledge of the genus. The genus comprises perennial herbs with fleshy root-tubers and rhizomes bearing separate vegeta- tive and reproductive stems. The leaves are resu- pinate, the flowers usually zygomorphic and pat- terned, and the fruit is a 3-valved loculicidal capsule. During a recent revision of Alstroemeria from Brazil, two distinctive new species were discovered in savannas. These species are here described. Alstroemeria stenophylla M. C. Assis, sp. nov.

Leaves of the vegetative stem 1.5-15 x 0.3-0.5 cm, resupinate, chartaceous, concentrated toward the apex, linear-lanceolate, apex acuminate, base truncate, both faces glabrous with prominent veins; leaves of the reproductive stem 0.84.5 x 0.2-0.3 cm, resupinate or not, coriaceous, distrib- uted along the stem, linear-lanceolate, apex acu- minate, base truncate, both faces glabrous with prominent veins. Inflorescence an umbel-like sim- ple cyme of 3 to 5 flowers; pedicel glabrous, 1-4 cm long, bracts leaf-like, chartaceous, 0.6-2 x 0.1 cm. Flower patent, campanulate, red or orange, 2- 3.8 cm long. Tepals 6 in 2 whorls; outer tepals not patterned, narrowly obovate or oblanceolate, apex apiculate, base attenuate; the upper ca. 3 x 0.9 cm; the lower ones ca. 2.7 x 0.9 cm, inner tepals ruby-spotted, all three very similar, narrowly ellip- tic-spatulate, apex acuminate, base attenuate; the upper tepals ca. 3 x 0.8 cm; the lower one ca. 2.5 x 0.7 cm. Stamens 6, included, filaments papillate at base, ca. 1.5 cm long; stigma included, style gla- brous, about 1 cm long. Capsule ovoid, 0.9-1.2 X 0.S1.2 cm. Distribution and phenology. Alstroemeria sten- ophylla is found on the rocky outcrops and on riv- erine forest borders in the states of Goias and Mi- nas Gerais in Brazil. Flowers: March and May. Fruit: May.

The flower is similar to that of the sympatric Al- stroemeria gardneri, which is differentiated by its coriaceous elliptical or obovate leaves7 distributed along the vegetative stem. The vegetative stem of the new species is similar to that of A. plantaginea Martius ex Schultes & Schultes f., but in this latter species the leaves are elliptical or oblong and the inner tepals are ruby-maculate.

Leaves of the vegetative stem 2-5 x 0.8-2.5 cm, resupinate, coriaceous, sessile, con- centrated at the apex or distributed along the stem, widely elliptic, oblong or obovate, apex acute, base attenuate, both faces glabrous with prominent veins; leaves of the reproductive stem 1-1.2 x 0.3- 0.5 cm not resupinate, chartaceous, sessile, dis- tributed only in the upper half of the stem, lance- olate, apex acuminate, base cuneate, both faces glabrous. Inflorescence an umbel-like simple cyme of 2 to 4 flowers; pedicel glabrous, ca. 3 cm long; bracts leaf-like, chartaceous, 0.5-1.2 x 0.1-0.2 cm. Flowers patent, campanulate, reddish, 3.5-3.8 cm long; outer tepals not patterned, these three similar, oblong-spatulate, apex acute or acuminate, base attenuate; upper one 2.3 x 0.6 cm; lower two 3.1 x 0.5 cm; inner tepals ruby-maculate, these three similar, spatulate, apex apiculate, base atten- uate, distal margin entire; upper two 3.3 x 0.6 cm; lower one 2.8 x 0.4 cm; stamens included, fila- ments glabrous, ca. 2.3 cm long; stigma included, style glabrous, ca. 2 cm long. Fruit not seen. Distribution and phenology. Alstroemeria tom- bolatoana is rarely found in the savannas of the states of Tocantins, Goias, and Mato Grosso. Flow- ers: April and June. Alstroemeria tombolatoana may be recognized by its coriaceous leaves, outer tepals oblong-spatulate, without patterning, but the inner tepals spatulate and ruby-maculate. This species is sympatric with A. gardneri, which has elliptical to rounded-spat- ulate outer tepals and elliptical-spatulate ruby- spotted inner tepals. The epithet of the new species, tombolatoanaS is in honor of Antonio Fernando Caetano Tombolato, a researcher at the Agronomic Institute of Campi- nas in Sao Paulo State (Brazil), who stimulated and assisted me in the beginning of my work with data gathered during several years of research with Al- stroemeria.
