Manipulus rubiacearum—VI

In neotropical Rubiaceae, nine new species for Brazil and one new generic section are described. Six new combinations and two new statuses are proposed, and the author citation ofPsychotria racemosa is corrected.Augusta is expanded to includeLindenia with nomenclatural adjustments, andAnthospermopsis is raised from a section to a genus.

RARITEBE, AN OVERLOOKED GENUS OF THE RUBIACEAE

Raritebe contains one species with two subspecies, the latter differing significantly in floral biology.Raritebe palicoureoides subsp.palicoureoides is heterostylous and is known from the Cordilleras Central and Oriental in Colombia and from east of the Andes in Ecuador and northeastern Peru;R. palicoureoides subsp.dwyeranum is homostylous and known only from west of the Andes in Colombia and from Panama and Costa Rica. The most probable hypothesis is that the selfincompatible subsp.palicoureoides gave rise to subsp.dwyeranum through genetic crossing over followed by long distance dispersal of the resulting self-compatible progeny. Coherent anthers with an unusual method of pollen release are characteristic of subsp.dwyeranum.Raritebe palicoureoides subsp.dwyeranum andR. palicoureoides subsp.palicoureoides var.antioquianum are described as new.

Rubiaceae Types in the Triana Collections at the Instituto de Ciencias Naturales, Universidad Nacional, Bogota, Colombia

Summary Jose Jer6nimo Triana was one of the most important collectors in 19th Century Colombia. The history of his collection and its numbering after his active period of collecting are traced. He employed a dual numbering system and prepared two separate catalogues for his collection. The set now at the Instituto de Ciencias Naturales, Universidad Nacional, Bogota (COL) is numbered systematically, and the sets deposited in European herbaria, particularly the British Museum (Natural History) (BM), are numbered serially from 1 to 4490. Consequently many important cited duplicates and types of Trianas collections at COL are not indicated as such; 26 previously unrecognized type collections of Triana Rubiaceae at COL are presented. Some collections in the Triana herbarium may actually be Linden duplicates.

Review of the genus perama (Rubiaceae)

The nomenclatural and taxonomic history of the genusPerama Aubl. (Rubiaceae) is discussed. The major trends of evolution within the genus are characterized, and the sections of the genus are delimited. A new section,Diperama Kirkb. & Steyerm., is described. The distribution of the genus is updated, and centers of species concentration are indicated. A complete synonymy is given for the genus, and the type species cited. An artificial key to the species is given ; a new combination,P. parviflora (Standl.) Kirkb. & Steyerm., is mads; and three new species are described,P. harleyi Kirkb. & Steyerm.,P. irwiniana Kirkb. & Steyerm., andP. sparsiflora Standl. ex Steyerm. & Kirkb.

Confirmation of hybridization between Declieuxia fruticosa and D. passerina (Rubiaceae)

A mixed population involvingDeclieuxia fruticosa (Willd. ex R. & S.) O. Kuntze,D. pas-serina Mart. & Zucc. ex Schult. & Schult., and a third, morphologically variable group of plants ofDeclieuxia was encountered on Serra do Cipó, Minas Gerais, Brazil. An analysis was made of dried, individual plants of the population using the following techniques: construction of a hybrid index and scatter diagrams from morphological characters, and determination of pollen fertility. Hybridization betweenD. fruticosa andD. passerina was confirmed, and introgression is strongly indicated.

A New Weed in Florida, Spermacoce latifolia, and the Distinction between S. alata and S. latifolia (Spermacoceae, Rubiaceae)

ABSTRACT  Spermacoce alata Aubl. and Spermacoce latifolia Aubl., frequently referred to as Borreria alata (Aubl.) DC. and Borreria latifolia (Aubl.) K. Schum., were described in the 18th century by Jean Baptiste Christophe Fusée Aublet from French Guiana. They have sometimes been treated as a single species but are two easily distinguished species. Spermacoce alata occurs from Venezuela through the Guianas and in the eastern Amazon basin north of the Rio Amazonas and is not weedy. The New World distribution of S. latifolia is from southern Mexico through Central America and throughout eastern South America to Bolivia and Paraguay, and it is naturalized in the tropical and subtropical regions of the Old World. Spermacoce latifolia is a noxious weed that has frequently been misidentified as S. alata. The first documented reports of S. latifolia in Florida are presented. Given its aggressive colonization elsewhere, prompt consideration should be given to controlling the spread of S. latifolia in the southern USA.

Taxonomic revision of the genus Catalpa (Bignoniaceae)

A taxonomic revision of Catalpa (Bignoiaceae), a genus of perennial trees frequently used in horticulture as garden and street trees, is provided. Eight natural species and two hybrid species are recognized, four in sect. Catalpa, four in sect. Macrocatalpa, and two hybrid species in sect. Catalpa. Although C. punctata has been used for one of the tropical species, C. macrocarpa is the correct scientific name. Catalpa tibetica is synonymous with C. bignonioides, C. fargesii with C. bungei, and C. obovata with C. macrocarpa. Lectotypes are designated for: Bignonia cassinoides, Bignonia longisiliqua, Bignonia longissima, Catalpa Walter, Catalpa subsect. Corymbosae, Catalpa bignonioides var. kaempferi, Catalpa bungei, Catalpa bungei var. heterophylla, Catalpa bungei var. intermedia, Catalpa domingensis, Catalpa fargesii, Catalpa henryi, Catalpa ×hybrida, Catalpa ovata var. flavescens, Catalpa punctata var. lepidota, Catalpa purpurea, Catalpa syringifolia var. pulverulenta, Catalpa sutchuensis, Catalpa ×teasii, and Cumbulu. Second-step lectotypes are designated for: Catalpa duclouxii, Catalpa ekmaniana, Catalpa oblongata, Catalpa obovata, and Catalpa ovata. Neotypes are designated for: Bignonia triloba, Catalpa aureovittata, Catalpa bignonioides var. variegata, Catalpa ×erubescens, Catalpa ×erubescens f. purpurea, Catalpa ×galleana, Catalpa ×hybrida var. atropurpurea, Catalpa japonica, Catalpa syringifolia var. aurea, Catalpa syringifolia var. koehnei, Catalpa syringifolia var. nana, Catalpa ×teasiana, and Catalpa umbraculifera.
