Chimborazoa (Sapindaceae), a new genus from Ecuador

Paullinia lachnocarpa has been known only from flowering and immature fruiting material collected in Ecuador. A recent collection with mature fruit shows that this biternate-leaved plant with multi-stelar stems and schizocarpic (indehiscent) fruit is best placed in its own genus,Chimborazoa. The only known species isChimborazoa lachnocarpa, which appears to be endemic to mountainous areas (1200–2000 m) in the provinces Chimborazo and Cotopaxi, Ecuador. The pollen morphology ofChimborazoa differs from that ofPaullinia. The lectotypification ofP. lachnocarpa is discussed, the new genus is described and illustrated, and a key to the genera of the Paullinieae is provided.

Favia camranensis sp. n. (Scleractinia: Faviidae), a new coral species from Southern Vietnam

A new species of coral, Favia camranensis sp. n., from the Hon Nai reef, Cam Ranh Bay, in southern Vietnam is described. This coral differs from all known faviids in that its corallites project one above another by more than 2 mm. The septa and septa-costae are heavily ornamented with complexly serrated trabecular spines. This coral can form monospecific aggregations of 5–20 colonies.     

<Emphasis Type="Italic">Acer binzayedii</Emphasis> (Sapindaceae), a new maple species from Mexico

Acer binzayedii, a new species of Sapindaceae from cloud and high elevation forests in Jalisco State, Mexico, is described and illustrated. Acer binzayedii is characterized by deeply sagittate anther bases bearing scattered trichomes, the wing sulcus covering more than half of the nutlet, sparsely distributed coalescent and anastomose veins of the wings with reticulate veinlets sometimes present, trichomes on the abaxial leaf surfaces with short nodulations of reduced prominence, conical buds, and grey bark with long vertical ridges. The new species is compared to putative relatives A. skutchii, A. floridanum, A. saccharum, A. grandidentatum, and A. nigrum.     

Penstemon pinorum (Scrophulariaceae), a new species from Utah

Penstemon pinorum, from the Pine Valley Mountains of southwestern Utah, is described and illustrated. It is compared morphologically and ecologically to other members of sectionCristati.     

Draba streptobrachia (Brassicaceae), a new species from Colorado

Draba streptobrachia Price is an alpine species endemic to Colorado, U.S.A. It was treated byHitchcock (1941) asDraba spectabilis var.dasycarpa (Schulz) C. L. Hitchc., but is distinct fromD. spectabilis Greene in morphology, habitat, and chromosome number (g = ca 32 inD. streptobrachia, versusg = 10 and 16 inD. spectabilis) and therefore has been raised to the rank of species. Pollen fertility inD. streptobrachia is at or near zero and anthers consistently fail to dehisce, but fertile seeds are still produced, suggesting that the taxon reproduces by agamospermy.     

Marila spiciformis (Bonnetiaceae), a new species from Peru

The new species,Marila spiciformis from Amazonian Peru, is described and illustrated. Relationships with other species are discussed.     

Dioon merolae (Zamiaceae), a new species from Mexico

A new species ofDioon found in northwestern Chiapas is characterized by linear-lanceolate leaflets arising at an acute angle from the rachis, obliquely inserted on it and imbricate.     

Kniphofia monticola (Liliaceae), a new species from Malawi

Genista valsecchiae (Leguminosae), a new species from Sardinia

Genista valsecchiae from SW Sardinia is described and illustrated as a species new to science. It is very similar toG. ephedroides and can be distinguished by morphological differences of habit and inflorescence. It typically occurs in the garigue or maquis and is widespread in SW Sardinia.     

Ayenia saligna (Sterculiaceae), a new species from Colombia

Ayenia saligna from Colombia is described and illustrated. It is remarkable for having foliar nectaries, which now are known to occur in seven of the 75–80 species in the genus. The petals ofAyenia are structurally complex and the inconsistent use of terminology to describe their parts is noted. In addition, the relationship ofA. saligna to other species ofAyenia is discussed.
