New and existing collections of Batrachospermum pseudogelatinosum Entwisle & Vis, and related taxa, from Australia and New Zealand, were analysed to determine whether this morphologically diverse taxon should be further subdivided. In particular, the value of the taxonomic character 'dioecy/monoecy' was assessed with molecular (rbcL gene sequences), morphometric and diagnostic morphology datasets, and its applicability more widely within the genus considered in light of our results. While the rbcL sequences supported our intuitive feeling that there is great variability within this taxon, there was no practical way to subdivide B. pseudogelatinosum. We recommend the acceptance of a broadly circumscribed paraphyletic species (paraspecies), B. pseudogelatinosum, which includes both dioecious and monoecious populations. The value of monoecy/dioecy as a character must be determined on a taxon-by-taxon basis—it is no better or worse than any other taxonomic character. Batrachospermum pseudogelatinosum occurs in eastern Australia and Stewart Island in New Zealand, with implications for the circumscription of B. campyloclonum Skuja ex Entwisle & Foard.

Abstract. Hapsari L, Trimanto, Wahyudi D. 2019. Species diversity and phylogenetic analysis of Heliconia spp. collections of Purwodadi Botanic Garden (East Java, Indonesia) inferred by rbcL gene sequences. Biodiversitas 20: 1266-1283. Heliconia L. is a single genus in the family Heliconiaceae, with approximate consists of 200 species. It has wide morphological variations among and within species which led to problems in species identification. Species diversity and phylogenetic analysis using morphology and rbcL marker subjected to 17 Heliconia spp. living collections of Purwodadi Botanic Garden (PBG) have been conducted. The rbcL gene located in chloroplast genome is one of appropriate proposed marker for plant barcoding assessment. This study aimed to study morphology and genetic variability of the PBG Heliconiaceae collections, to confirms the species name for a more accurate identity record and to reveal the diversity and phylogenetics of the species. Morphological characterization showed high variability among Heliconia species, which included 3 subgenera (Heliconia, Stenochlamys, and Griggsia) and 1 hybrid. Each species possessed unique morphological characteristics. The common morphological characters which distinguished among and within Heliconia species includes leaf form, inflorescence type, and bract characteristics. Key to the Heliconia species examined is presented in this paper. However, molecular confirmation using rbcL sequences showed high conservation level (0.932) and low genetic variability. About 656 nucleotides were monomorphic and 33 positions were polymorphic which comprised 18 singleton variable sites and 15 parsimony informative sites. Twelve haplotypes were produced with haplotype diversity value 0.8952. Pairwise distance analysis shows that they were shared high similarity of rbcL sequences with very low genetic distance (0.022 to 0.000). The topology of phylogenetic tree resulted by Neighbour-Joining algorithm has the best grouping and be able to explain the relationship among species of Heliconia, although supported by low bootstrap (65). It was separated into two clades following its subgen. classification. Clade 1 consists of subgen. Heliconia and Griggsia; while clade 2 consists of subgen. Heliconia and Stenochlamys; also hybrid species. Further, separation of deeper branchings (section) was inconsistent and unclear. Upon this study, rbcL marker was considered too conserved thus less valuable for phylogenetic analysis at lower taxa among and within Heliconia spp. However, rbcL was suggested to distinguish at higher level taxa between closely related genus and above.

Abstract Total DNA was extracted from 41 species (20 genera) of the subfamily Nepetoideae (family Labiatae). Using rbcL-specific primers, the rbcL gene was amplified by polymerase chain reaction (PCR) and sequenced directly. RbcL sequences were evaluated with character state (maximum parsimony; PAUP) and distance methods (neighbour-joining; MEGA). In agree­ ment with classical systematics all taxa studied cluster within the Nepetoideae and are clearly distinguished from members of the subfamily Lamioideae. A number of distinctive clades are apparent within the Nepetoideae:, and XIII -Perovskia. At least five main branches rep­ resenting the clades I, II, III to VII, VIII, and IX to XIII respectively, can be distinguished within the Nepetoideae studied. They might be considered representing the tribes (according to Cantino, 1992) Elsholtzieae (I), Lavanduleae (II), and Mentheae (III - XIII). The tribe Mentheae needs to be subdivided into at least three main groups (clades III-VII, VIII and IX -XIII). Major ana hortensis which is often classified as Origanum hortensis does not cluster with Origanum and deserves a generic status of its own.
