<i>DE MACROCARPAEAE GRISEBACH (EX GENTIANACEIS) SPECIEBUS NOVIS </i> VIII: FOUR NEW SPECIES FROM ECUADOR
Two new species, Macrocarpaea claireae and M. quizhpei (Gentianaceae: Helieae), are described from the Huancabamba region of southern Ecuador. Macrocarpaea claireae occurs around Valladolid, adjacent to P. N. Podocarpus, and M. quizhpei occurs in the Nangaritza watershed. M. claireae is closely related to M. pringleana and M. sodiroana, yet differs notably in its glaucous-green, campanulate-urceolate calyx. Macrocarpaea quizhpei has affinities to M. dies-viridis, but differs in having a large, diffusely branched, open thyrse to 1.3 m high
New combinations and names in Andean Pitcairnia, Tillandsia, and Werauhia
The following eight new combinations are made based on transfers from Pepinia and Vriesea: Pitcairnia holstii (H. Luther) J. R. Grant, P. minicorallina (H. Luther) J. R. Grant, P. neeana (L. B. Sm. ex H. Luther) J. R. Grant, P. peruana (H. Luther) J. R. Grant, Tillandsia appenii (Rauh) J. R. Grant, T. gruberi (Ehlers) J. R. Grant, T. lutheri (Manzan. & W. Till) J. R. Grant, and T. piepenbringii (Rauh) J. R. Grant. Additionally, three new names are proposed: Tillandsia frank-hasei J. R. Grant to replace Vriesea hasei Ehlers, T. walter-tillii J. R. Grant to replace V. tillii Manzan., and Werauhia rauhii J. R. Grant to replace V. patzeltii Rauh var. panamaensis Rauh at the species rank.O autor propõe oito novas combinações baseadas na transferência de espécies dos gêneros Pepinia e Vriesea, a saber: Pitcairnia holstii (H.

Grant para substituir, no status de espécie, V. patzeltii Rauh var. panamaensis Rauh

<i>DE MACROCARPAEAE GRISEBACH (EX GENTIANACEIS) SPECIEBUS NOVIS </i> IX: A SYNOPSIS OF THE GENUS IN BOLIVIA
A synopsis of the genus Macrocarpaea in Bolivia is presented. Four species are recognized including M. bangiana Gilg, M. cinchonifolia (Gilg) Weaver, M. cochabambensis Gilg-Ben., and M. fuentesii J.R. Grant, sp. nov. These are the four southernmost species of Macrocarpaea in the Andes
<i>DE MACROCARPAEAE GRISEBACH (EX GENTIANACEIS) SPECIEBUS NOVIS </i> VI: SEED MORPHOLOGY, PALYNOLOGY, AN INFRAGENERIC CLASSIFICATION , AND ANOTHER TWENTY-THREE NEW SPECIES LARGELY FROM COLOMBIA
A brief survey of seed morphology and palynology in Macrocarpaea is discussed and illustrated by Scanning Electron Microscopy (SEM) photographs. An infrageneric classification is presented where four sections are recognized: sect. Tabacifoliae, sect. Macrocarpaea, sect. Magnolifoliae, and sect. Choriophylla. Another 23 new species, largely from Colombia, are here described and illustrated: Brazil (1): M. illecebrosa; Colombia (14): M. betancuriana, M. callejasii, M. gaudialis, M. gondoloides, M. gravabilis, M. gulosa, M. hilarula, M. jocularis, M. lacrossiformis, M. laudabilis, M. maryae, M. silverstonei, M. umerulus, and M. ypsilocaule; Ecuador (4): M. berryi, M. jactans, M. neillii, and M. voluptuosa; and Peru (4): M. chthonotropa, M. granpajatena, M. quechua, and M. xerantifulva
The <i>Tillandsia adpressa</i> Assemblage: A Review and New Combinations in <i>Racinaea</i> (Bromeliaceae: Tillandsioideae
Studies of the Bromeliaceae have led to a reevaluation of the four-taxa Tillandsia ad- pressa Andre assemblage. Herbarium research and field studies show that three of the taxa in the assemblage should be recognized at the specific rank, while the remaining one should be transferred to subspecific status. All taxa are transferred to Racinaea as follows: R. adpressa (Andre) J. R. Grant, R. adpressa subsp. orthiantha (Standley) J. R. Grant, R. miniata (Rauh) J. R. Grant, and R. schumanniana (Wittmack) J. R. Grant. A discussion of the nomenclature, lists of exsiccatae, and a key to the taxa are provided
Xerxes, a new name to replace Alcantara (Asteraceae: Vernoniae)
Xerxes is proposed as a new name to replace Alcantara Glaziou ex G. M. Barroso (Asteraceae) (1969), not Alcantarea (Morren ex Mez) Harms (Bromeliaceae) (1929). The genus is monotypic, represented by Xerxes ekmanianum, comb. nov
<i>DE MACROCARPAEAE GRISEBACH (EX GENTIANACEIS) SPECIEBUS NOVIS </i> VII: FOUR NEW SPECIES AND TWO NATURAL HYBRIDS
Four new species, Macrocarpaea dies-viridis (Ecuador), M. luctans (Ecuador, Peru), M. lucubrans (Panama), and M. opulenta (Ecuador), and two natural hybrids, M. × acuminata (Costa Rica) and M. × mattii (Ecuador), are described. Macrocarpaea × acuminata Weaver (pro sp.) is recognized as a natural hybrid between M. subcaudata and M. valerii, rather than as a distinct species, and M. × mattii is described here as a natural hybrid between M. noctiluca and M. subsessilis. The average number of seeds per capsule of M. dies-viridis is reported. With 10,400–11,000 seeds per capsule, the is first report in the genus
