Scientific Scientific A new species of Racinaea (Bromeliaceae) from Peru Eric John Gouda and José Manuel Manzanares. Photographs by Philip Wittman. By coincidence both authors were initially working independently on manuscripts describing material that, we later found out, related to the same new species. Manzanares had the specimen collected by Robin B. Foster on loan from the Missouri Botanical Garden (MO) and Gouda was working on the C. Porter et al. specimen after Ricardo Fernández contacted Gouda by email for a name for their 3 collections from Cuzco. The much smaller Foster specimen has been chosen for the holotype because it was collected at anthesis. This specimen seems to be slightly more bulbose than the comparatively utriculate Porter et al. collections. The taller plants of the Porter et all. collections are from the Dept. of Cuzco and are collected not more than 50 km apart of each other, but the Foster collection is 500 km to the North-East in the Dept. of Pasco. All collections are from the damp montane forest at the Amazonian side of the main ridge of the Andes, Peru. Racinaea penduliflora Gouda & Manzan., sp.nov.

Brown, Walter Till, Elton Leme, and Jason Grant Figure 3. Racinaea penduliflora showing the reddish colouration of the leaf base and margins and some spotting, and an old inflorescence (coll. PE08-358) Etymology: “Pendulus” means hanging, pendent; “-flora” is flowered (with hanging flowers). A typical aspect of this species is the pendent spikes and flowers, which is rare in Racinaea. Especially the first flowers in a spike are strongly downwardly secund, the ones toward the apex are downward (pendent) because of the pendent curving spike. Discussion: This new species resembles Racinaea flexuosa, R. pallidoflavens and R. kessleri and can be distinguished from these and other species by a combination of following characteristics: Plant flowering 30-40 cm tall with an utriculate rosette. Leaf-blades triangular, ca. 3 cm wide at the base, cinereous-lepidote. Inflorescence bent over to one side, twice to thrice branched with distinctly stipitate branches, the spikes archingpendulous. Flowers at the base of the spikes downwardly second, the apical ones pendulous with the spike. Floral-bracts carinate, densely lepidote, exceeded by the 6 mm long sepals.

Manzanares: Curator of Bromeliaceae at QCNE, Quito, Ecuador. 158 JBS 58(4). 2008 Recently, volume 5 of Flora Fanerogamica do Estado de Sao Paulo was published (Melhem, Wanderley et al. 2007). This contribution to the flora of São Paulo state, Brazil covers an interesting group of 12 flowering plant families, one monocot (Bromeliaceae) and eleven dicots (Araliaceae, Basellaceae, Bombacaceae, Cactaceae, Ebenaceae, Flacourtiaceae, Menispermaceae, Phytolaccaceae, Podostemaceae, Quiinaceae, Rubiaceae). This review concerns only the Bromeliaceae treatment coordinated by Wanderley & Martins (Wanderley and Martins 2007). Based on approximately 2700 herbarium specimens (exicata) 16 authors (Table 1) recognize 149 species in 18 genera, and four undescribed species (1 Aechmea, 3 Vriesea) of bromeliads from São Paulo state, Brazil. In general, the structure and information within this floristic treatment of Bromeliaceae adheres to normal conventions for this type of work. In addition to a general technical description for the family there is a key to genera, a brief description for each genus, and species-level keys where appropriate. For each species there are descriptions, brief notes on distribution, a list of selected material examined, and commentary on taxonomy and noted variations. A total of 29 plates are included that illustrate one or more aspect, usually habit, for 65 of the 148 recognized species. This contribution is significant because it represents the first published floristic treatment of Bromeliaceae for São Paulo state. There are, however, a number of curious features about the work that detract from its value. In the key to genera, and in the generic description for Bromelia, the rosette of leaves is characterized as forming a tank, a condition not associated with the genus, and for a neophyte this would likely lead to identifying a Bromelia specimen as Acanthostachys when using this key. Application of the tank habit to Bromelia broadens the morphological concept of the tank to a point where it becomes synonymous with rosette, and thus has no diagnostic significance. There is some confusion concerning the listed exicata as part of each species treatment. For example, “Material Selecionado”, a list of one to several selected specimens used to document each species is used most often, but then “Material Examinado”, is also encountered in other cases (e.g., Aechmea lingulata, Vriesea vulpinoidea). The mixed use of Material “Selecionado” and “Examinado” is most likely an editorial error and probably goes unnoted by most users. However, because the specimens examined are the data upon which a scientific floristic treatment is based, specimen citation needs to be clear. This brings us to the “Lista de exsicatas”, or list of herbarium specimens examined for the entire family treatment. Estimated at approximately 2,700, this list is not reader/user-friendly. For example, an entry consists of the collector’s last name and initial(s), followed by the collection number and finally JBS 58(4). 2008 159
