Anthurium truncatum is published as a new name for the Brazilian A. brachypodum G. M. Barroso of 1957, because the latter name was preoccupied by the Ecuadorian A. brachypodum Sodiro of 1901. A. truncatum is a rare species, only known from the type collection and a recent collection made 15 km away from the type locality. It is re-described and illustrated, and its sectional relationship is discussed.

Two new species of Araceae from South America are described and illustrated. The one is Anthurium ensifolium from Bahia, eastern Brazil, which is tentatively placed in A. sect. Urospadix subsect. Obscureviridia. It seems close to A. cleistanthum, a poorly known species from Esp\írito Santo, Brazil, and also resembles A. erskinei from Bahia. The other is Gorgonidium bulbostylum from Andean Bolivia, which differs from all other species of the genus by the unusual aspect of the style that has an inflated, more or less ovoid apical portion. The stigma is also peculiar in being globose and conspicuously lobed, with lobes upwardly directed.

The tribe Spathicarpeae is one of the most poorly known-tribes in the Araceae. Recently, field collections in some areas of Bolivia have revealed many interesting members of this tribe. Two new species, Gorgonidium striatum Hett., P. L. Ibisch \& E. G. Gon\ç. and Spathantheum fallax Hett., P L. Ibisch \& E. G.

A new rheophytic species of Philodendron , viz. P. carajasense E. G. Gon \ç . \& A. J. Arruda sp. nov., is described from the Caraj\ás region, northern Brazil. Th is is the second rheophyte described in the genus, the first being P. flumineum E. G. Gon\ç . to which P. carajasense seems to be related. Th e new species is also compared with the closely related sympatric P. guttiferum , but the latter lacks the rheophytic habit. The new species is thought to be endemic to the Caraj\á s region.

Two new species of Xanthosoma sect. Acontias, X. mariae and X. latestigmatum, are described and illustrated. They have pilose, pedate leaf blades as have in Xanthosoma only X. plowmanii and X. pottii, and their pollen grains are released as monads, unlike in all other Xanthosoma species, which, as far as studied, release the pollen in tetrads. X. mariae is an evergreen plant mainly distinguished by its dark green velvety lustrous leaf blades with numerous leaflets and tuber-like swellings at the junction of petiole and blade; the gynoecium is of the Acontias type and the ovary is pilose in the lower part. X. latestigmatum is seasonally dormant and has medium green leaf blades with numerous leaflets and no tuber-like swellings; the gynoecium is of the Caladium type (with a very broad stigma) and completely glabrous. The relationship of the genera Caladium and Xanthosoma is discussed, C. paradoxum is transferred to Xanthosoma and the new combination X. paradoxum validated, and a key to the genera of the tribe Caladieae given.

The species originally described as Caladium poecile Schott (Araceae) is here proposed as belonging to the genus Xanthosoma, as X. poecile (Schott) E.G. Gon\ç.. This new combination is based on pollen grains (shed in tetrads), together with molecular results. This is the third species of Xanthosoma known to have peltate leaves.

The genus Xanthosoma Schott is widely cultivated in the tropics, but very little is known about its taxonomy, especially concerning the cultivated species. This article presents a key for determination, as well as morphological descriptions and additional information about 14 forms/species of commonly cultivated Xanthosoma, including four new species.

Limestone outcrops are considered insular biomes for plants that need richer soils mainly in areas such as Central Brazil, in which poor soils are clearly predominant. Because of this peculiar situation, plants restricted to these areas are clearly threatened by limestone mining. In Central-western Brazil, at least 6 aroid genera (Anthurium, Asterostigma, Philodendron,\ \ \ \  Spathicarpa, Taccarum and Xanthosoma) and 18 species can be found growing in limestone outcrops and are here briefly described and illustrated.

These new species are all illustrated and compared to their closest relatives. Caladium intermedium is noteworthy in appearing intermediate between Caladium and Scaphispatha, turning the boundaries between both genera rather complex.

Since it was described by Adolf Engler in 1880, the exact identity of the Brazilian Taccarum warmingii has remained obscure. Recently, the type material of this species was examined and a new collection was made in Espirito Santo state, Eastern Brazil. Taccarum warmingii is described in details and illustrated, also based on living specimens now in cultivation. A revised key for the genus Taccarum is also presented.

A new species of Philodendron (P. lupinum) is described from Acre state, Brazil. It seems to be closer to the species of subgenus Philodendron section Philodendron series Impolita Croat (P. hebetatum, P. strictum and P. thalassicum), but differs from these species by the conspicuously panduriform anterior division and for the presence of fewer ovules per locule. This new species is so far known only from
