“…These forests are still poorly known floristically and only a few surveys exist (Felfili & Silva Junior 1992, FZDF 1990, Heringer & Paula 1989, Oliveira-Filho et al 1990, Paula et al 1990, Ratter 1980, Ratter et al 1973, Seabra et al 1991, UFPR/FZDF 1972. Thus, ecological restoration is extremely difficult.…”

Diameter increments, recruitment and mortality were studied over a six-year period in a 3.02 ha sample in an area of 64 ha of undisturbed gallery forest alongside the Gama stream. The study site is located in Fazenda Agua Limpa in Brasilia, Federal District, Brazil. Trees 2=31 cm gbh (10 cm dbh) were measured every three years from 1985 in 151 (10 m X 20 m) permanent plots in Gama forest.The mean annual diameter increment for trees ^10 cm dbh was 0.25 cm y" 1 . Variability was high with coefficients of variation c. 100% or more. Light-demanding and large upper storey species tended to grow faster than shade-tolerant and lower storey species. Mean increments for the community increased with increasing diameter classes.The mean annual mortality rate for the community was 3.5% y" 1 while the recruitment was 2.7%. The community was dynamic with 86% of all species either suffering mortality or gaining recruits or both during the six years. The net difference between recruitment and mortality was zero for 55 species. The recruitment compensated for the mortality of most of the abundant species.

“…Sendo grande a heterogeneidade ambiental e florística destas matas (Gibbs & Leitão-Filho 1978;Bertoni & Martins 1987;Heringer & Paula 1989;Oliveira-Filho 1989;Oliveira-Filho et al 1994;Felfili 1994Felfili , 1998Carvalho et al 1995;Meguro et al 1996;Metzger et al 1998;Silva-Júnior 1999Pinto & Oliveira-Filho 1999;Vilela et al 1999;Berg & Oliveira-Filho 2000;Morais et al 2000;Sampaio et al 2000;Bertani et al 2001;Silva-Júnior et al 2001;Marimon et al 2002), formando mosaicos de vegetação, a flora fanerogâmica de uma mata pode variar consideravelmente em distâncias relativamente curtas, o que leva à necessidade de que se protejam áreas amplas e largas para que resultados satisfatórios possam ser obtidos nas práticas de conservação florística. Focado nessa questão, Silva-Júnior (2001) analisou a efetividade da legislação ambiental vigente (Lei n. 7.511, de 7/julho/1986) para conservar a diversidade florística encontrada nessas matas.…”

RESUMO -(Fitossociologia de dois trechos inundáveis de Matas de Galeria no Distrito Federal, Brasil). As Matas de Galeria do biomaCerrado possuem peculiaridades fisionômicas e florísticas que permitem separá-las em dois subtipos: "não-inundável", quando em solos bem drenados; e "inundável", o subtipo menos estudado, em solos mal drenados. O presente trabalho objetivou caracterizar estrutural e floristicamente dois trechos inundáveis das matas dos córregos Acampamento (15°35'S; 48°10'W) Palavras-chave: fitossociologia, diversidade, mata de galeria, Riacho Fundo, Acampamento, Distrito Federal ABSTRACT -(Phytosociology of two swamped portions of gallery forests in Distrito Federal, Brazil). Gallery forests in the Cerrado biome possess physiognomic and floristic peculiarities that allow its division in two subtypes: "non-swamp" located in well drained soils; and "swamp" the less studied subtype, located in badly drained soils. The present study aimed to characterize the structure and the flora of two swamped portions in the gallery forests of the Acampamento stream (15°35'S; 48°10'W) and the Riacho Fundo stream (15°55'S and 48°02'W), both in Distrito Federal (DF). In each forest it was allocated a grid of 160×50 m (0.8 ha), composed by 40 plots of 10×20 m (200 m 2 ). All the individuals with DBH ≥ 3.0 cm were surveyed, including the standing dead plants. It was sampled 6,078 individuals, being 3,030 in the swamped portion of Acampamento stream (33 families, 49 genera and 60 species) and 3,048 in the Riacho Fund portion (30 families, 41 genera, 53 species). The basal area (dominance) and the diversity (H') for the studied portions were 47.96 m 2 /ha and 2.99 nats/ind. (Acampamento) and 41.28 m 2 /ha and 2.84 nats/ind. (Riacho Fundo), respectively. If compared to others gallery forests previously studied in Distrito Federal, such diversity values are considered low, although they are similar to that indicated for the "Swamp Forests" ("Matas de Brejo") of southeastern Brazil. The similarity indexes of Sørensen (58.0%) and Morisita (70.6%) point to high qualitative and quantitative similarity among portions. However the classification accomplished by TWINSPAN generated two distinct groups, each one linked to one of the portions studied (Acampamento and Riacho Fundo). These results reinforce previous indications that distinct gallery forests in Distrito Federal, or even similar portions on that, show different floristic patches. This variation are related to the hydrographic basin in which the gallery forest is inserted, and the soil drainage.

“…En realidad, I. pseudothea fue descripta en 1861 para Brasil, sin indicar localidad de colección (Reissek, 1861: 64). Es nativa del estado de Minas Gerais (Loesener, 1901: 454-456;Loesener, 1942: 78) y también ha sido mencionada en un trabajo no florístico para el Distrito Federal brasileño (Heringer & de Paula, 1989), es decir para bajas latitudes dentro del país vecino, bastante alejadas de la frontera argentino-brasileña. Esta especie estaría emparentada con Ilex amara (Vell.…”

Se confirma la exclusión de Ilex pseudothea Reissek de la flora argentina, tras el examen de los ejemplares coleccionados por Lorentz en la provincia de Entre Ríos. En consecuencia, esos materiales se determinan como Xylosma venosa N. E. Br. (Salicaceae), rechazando asimismo la posibilidad sugerida de que dichos especímenes pudieran pertenecer a Schinus (Anacardiaceae).
