Penstemon apateticus Straw is found to be synonymous withP. miniatus Lindl.Penstemon miniatus subsp.apateticus andP. miniatus subsp.townsendianus are presented as new combinations. *** DIRECT SUPPORT *** A01CT127 00005
Stryphnodendron moricolor (Mimosaceae) is described, illustrated and discussed. The genusMonopteryx (Fabaceae) is reported for the first time outside Amazonian Brazil and adjacent Venezuela. A key distinguishing the three known species ofMonopteryx is presented.
Spiranthes diluvialis, a species known from widely scattered localities in the western United States, is formally described. It has been confused in the past with a number of other species. Morphological characters and cytological data indicate an origin through hybridization ofS. magnicamporum andS. romanzoffiana.
Nectria atrofusca, a parasite ofStaphylea trifolia in eastern North America but extending as far west as Iowa, is redescribed. Its anamorph is described asFusarium staphyleae Samuels & Rogerson, sp. nov.
Four new species ofPectis are described:P. ericifolia from Barbuda,P. luckoviae from west-central Mexico,P. arida from Ecuador and Peru, andP. cajamarcana from Peru. Chromosome counts forP. ericifolia (n=48) andP. luckoviae (n=12) are presented. Relationships of the newly described taxa are discussed.
Polygonella ciliata var.basiramia andP. fimbriata var.robusta are raised in rank toP. basiramia (Small) Nesom & Bates, comb. nov., andP. robusta (Small) Nesom & Bates, comb. nov. Although the morphological similarity betweenP. ciliata andP. basiramia and betweenP. fimbriata andP. robusta is greater than between any other species of the genus, the sister species of each newly recognized...
Two new Colombian species ofHabracanthus,H. malacus from the Sierra Nevada de Santa Marta andH. latifolius from the Sierra de Perijá, are described, illustrated, and compared withH. antipharmacus, their closest relative.
Comparison of several critical morphological characters inAcer japonicum microphyllum Siesmayer andA. shirasawanum Koidzumi, show that the two taxa are identical; the former is synonymous withA. shirasawanum. Similarly, morphological data, supported by the chemical dichotomy of flavonols vs. glycoflavones withinAcer sectionPalmata, indicate thatA. japonicum aureum Siesmayer is in fact a form ofA. shirasawanum...
Eucharis plicata andPamianthe parviflora are described from Peru and Ecuador respectively. Additionally, questions are raised concerning the separation of the generaPamianthe Stapf andParamongaia Velarde.
Primula alcalina, endemic to east-central Idaho, is described and illustrated. Closely related toP. incana, it differs in having smaller flowers that are white instead of lilac, and a much lower chromosome number (n=9).
Bryosedgwickia is considered a synonym ofPlatygyriella and the following transfers are proposed:P. aurea, P. aureoides, P. densa, P. fragilifolia, P. kirtikarii andP. pringlei. A key is provided to the accepted species ofPlatygyriella. Excluded species are treated asHondaella entodontea (C. Müll.) Buck andIsopterygium jamaicense (Bartr.) Buck.
Trillium sulcatum, a new species with two petal color forms, was first circumscribed by Barksdale as a variety in 1938, but without a Latin diagnosis. It superficially resembles the mainly northernT. erectum and appears to be closely related to the primarily midwesternT. flexipes. Its distinguishing features are ringent flowers, short sepals, and long pedicels; additional characters are presented...
Tapura haitiensis was described in 1926 from sterile material from the Massif de la Hotte, Haiti. It was recollected in 1983 from the same area and its flowers and young fruit are described here for the first time together with habitat details. It is compared with three related species,T. orbicularis, T. panamensis, andT. cubensis.
The new genusPranceacanthus, apparently most closely related to the bitypic genusJuruasia, is described and illustrated. Its sole species,P. coccineus, has been collected on “terra firma” in lowland Amazonian Brazil in the states of Amazonas and Mato Grosso and in the territory of Rondônia.
