Deng, N.H. Xia & H. Peng (Acanthaceae), is described from the Hengduan Received 30 September 2016 Mountains, China. Wuacanthus is based on Wuacanthus microdontus (W.W.Sm.) Y.F. Deng, N.H. Xia & H. Received in revised form Peng, originally published in Justicia and then moved to Mananthes. The new genus is characterized by its 25 November 2016 shrub habit, strongly 2-lipped corolla, the 2-lobed upper lip, 3-lobed lower lip, 2 stamens, bithecous Accepted 25 November 2016 anthers, parallel thecae with two spurs at the base, 2 ovules in each locule, and the 4-seeded capsule. Available online xxx Phylogenetic analyses show that the new genus belongs to the Pseuderanthemum lineage in tribe Justi- cieae. Wuacanthus is closely related to Pseuderanthemum but differs from the latter by its shorter corolla Keywords: Acanthaceae tube and two minute spurs at the base of each anther-theca. W. microdontus is assessed with the status Jinshajiang Valley EN B2ab (iii) based on the IUCN Red List Categories and Criteria.

Introduction world (Graham, 1988; Mabberley, 2008; Hu et al., 2011). Two divergent trends were suggested by previous studies of the genus, Acanthaceae is a pantropical family consisting of about 230 resulting either in the recognition of a large number of small genera and 4000 species (Mabberley, 2008; Hu et al., 2011). Recent segregate genera or in the adoption of a very broad definition of phylogenetic studies of Acanthaceae have resulted in the recogni- Justicia. In the former, Bremekamp (1948) separated Justicia s.l. tion of four subfamilies, viz., Nelsonioideae, Thunbergiodeae, Avi- into several genera and his treatment was followed by many au- cennioideae and Acanthoideae. Acanthoideae differs from the other thors (e.g., Hu and Tsui, 2002). In contrast, Graham (1988) adopted three subfamilies in having reticulata and is further divided into a very broad definition of Justicia and divided the genus into 16 seven tribes, Acantheae, Ruellieae, Justicieae, Barlerieae, Neu- sections and 7 subsections. Graham's treatment was followed by rantheae, Andrographideae and Whitifieldieae (Reveal, 2012). Four the most recent works (Hu et al., 2011; Wood, 2014). The genus lineages were recognized by McDade et al. (2000) in Justicieae, viz., Justicia is characterized by several characters, including the 2- the Justicia lineage, Tetramerium lineage, Isoglossinae and Pseu- lipped corolla with the bilobed upper lip and trilobed lower lip, deranthemum lineage. two bithecous stamens, usually one thecae above the other, and Justicia L. is the largest genus in the family Acanthaceae and the lower one with a spur at the base (Graham, 1988, Hu et al., belongs to tribe Justicieae. It comprises approximately 600 species 2011). However, recent molecular evidence has indicated that and is distributed in the tropical and subtropical regions of the Justicia in the broad sense of Graham (1988) is paraphyletic (McDade et al., 2000; Gao, 2010).

Historical Setting of the Guianan Plant Heritage The Guianas are embedded high in the green shoulder of northern South America, an area once known as the "Wild Coast". They are the only non-Latin American countries in South America, and are situated just north of the Equator in a configuration with the Amazon River of Brazil to the south and the Orinoco River of Venezuela to the west. The three Guianas comprise, from west to east, the countries of Guyana (area: 83,000 square miles; capital: Georgetown), Surinam (area: 63, 037 square miles; capital: Paramaribo) and French Guiana (area: 34, 740 square miles; capital: Cayenne). Perhaps the earliest physical contact between Europeans and the present-day Guianas occurred in 1500 when the Spanish navigator Vincente Yanez Pinzon, after discovering the Amazon River, sailed northwest and entered the Oyapock River, which is now the eastern boundary of French Guiana.

The present study included 38 accessions of 28 species as sources of DNA data for one nuclear (nrITS) and four chloroplast (intergenic spacers: psbA-trnH, trnS-trnG, ndhF-rpl32, rpl32- trnL(uag)) regions to provide an estimate of the phylogeny of the genus. We found that Dyschoriste is strongly supported as monophyletic inclusive of Apassalus, Chaetacanthus, and Sautiera. Within Dyschoriste, three geographically cohesive lineages were recovered with moderate to strong support: a mainland African clade, a Caribbean and southeastern United States clade, and a South and Central America clade.

The dendrogram reveals that the five species under study exhibits an overall similarity of 60.7%. Avicennia alba and A. officinalis (cluster C1) have very close relationship between them and share a common node in the dendrogram at a 73.3% level of similarity. Avicennia marina and Acanthus ilicifolius (cluster C2) also have close relationship between them as evident by a common node in the dendrogram at 71.8% level of similarity. Acanthus volubilis showed 68.1% similarity with cluster C1 and 60.7% similarity with cluster C2. Our study also supported the view of placing Avicennia under Acanthaceae. Regarding the relative position of Avicennia within Acanthaceae, it was shown to be very close to Acanthoideae. In comparison to other species, A. marina showed most genetic variability, suggesting utilization of this species over others for breeding programme and as source material in in situ conservation programmes.

Bhatt*, Y. Naidoo and A. Nicholas School of Biological and Conservation Sciences, University of KwaZulu-Natal, Westville Campus, Private Bag X54001, Durban, KZN, 4000, South Africa ABSTRACT The micromorphology of foliar trichomes of Hypoestes aristata var. aristata was studied using stereo, light and scanning microscopy (SEM). This genus belongs to the advanced angiosperm family Acanthaceae, for which few micromorphological leaf studies exist. Results revealed both glandular and non-glandular trichomes, the latter being more abundant on leaf veins, particularly on the abaxial surface of very young leaves. With leaf maturity, the density of non-glandular trichomes decreased. Glandular trichomes were rare and of two types: long-stalked capitate and globose-like peltate trichomes. Capitate trichomes were observed only on the abaxial leaf surface, while peltate trichomes were distributed on both adaxial and abaxial leaf surfaces. Key terms: Acanthaceae, Glandular trichomes, Hypoestes aristata var. aristata, medicinal plant, Scanning electron microscope.

The triad all have floral venation similar to red, tubular-flowered species of Just icia, though they differ from most Justicia in their tricolporate pollen with distinct pseudocolpi. In pollen and anther characters they are similar to Anisacanthus and Carlowrightia, but they differ from these in corolla vascularization and anther presentation and from Carlowrightia in corolla size. As the three taxa do not appear to represent a monophyletic group, and as Stearn has placed taxa with similar pollen into what has become a holding genus, Justicia, we include these in Justicia by default until further studies can decipher relat ionships within the genus.

Saiful Islam Roney, Rownak Jahan, Mohammed Rahmatullah: Acanthaceae and Asteraceae family plants used by folk medicinal practitioners for treatment of malaria in Chittagong and Sylhet Divisions of Bangladesh ABSTRACT Malaria is a debilitating disease causing high mortality rates among men and women if not treated properly. The disease is prevalent in many countries of the world with the most prevalence noted among the sub-Saharan countries, where it is in an epidemic form. The disease is classified as hypo-endemic in Bangladesh with the southeast and the northeastern regions of the country having the most malaria-affected people. The rural people suffer most from malaria, and they rely on folk medicinal practitioners for treatment, who administer various plant species for treatment of the disease as well as associated symptoms like pain and fever. Plant species have always formed the richest sources of anti-malarial drugs, the most notable being quinine and artemisinin. However, quinine has developed drug-resistant vectors and artemisinin is considered by some to developing initial resistance, particularly in China, where it has been used for thousands of years to combat malaria.

Alzahrani1, Samaila S. Yaradua1,2*, Enas J. Albokhari1,3 and Abidina Abba1 Abstract Background: The plastome of medicinal and endangered species in Kingdom of Saudi Arabia, Barleria prionitis was sequenced. The plastome was compared with that of seven Acanthoideae species in order to describe the plastome, spot the microsatellite, assess the dissimilarities within the sampled plastomes and to infer their phylogenetic relationships. Results: The plastome of B. prionitis was 152,217 bp in length with Guanine-Cytosine and Adenine-Thymine content of 38.3 and 61.7% respectively. It is circular and quadripartite in structure and constitute of a large single copy (LSC, 83, 772 bp), small single copy (SSC, 17, 803 bp) and a pair of inverted repeat (IRa and IRb 25, 321 bp each). 131 genes were identified in the plastome out of which 113 are unique and 18 were repeated in IR region. The genome consists of 4 rRNA, 30 tRNA and 80 protein-coding genes. The analysis of long repeat showed all types of repeats were present in the plastome and palindromic has the highest frequency. A total number of 98 SSR were also identified of which mostly were mononucleotide Adenine-Thymine and are located at the non coding regions. Comparative genomic analysis among the plastomes revealed that the pair of the inverted repeat is more conserved than the single copy region.

    Northern Territory Naturalist (2016) 27: 29–35 Short Note Asystasia gangetica subsp. micrantha, a new record of an exotic plant in the Northern Territory John O. Westaway1, Lesley Alford2, Greg Chandler1 and Michael Schmid2 1 Northern Australia Quarantine Strategy, Commonwealth Department of Agriculture, 1 Pederson Road, Marrara, NT 0812, Australia Email: [email protected] 2 Veg North, PO Box 124, Nightcliff, NT 0814, Australia Abstract An herbaceous weed of the acanthus family, Asystasia gangetica subspecies micrantha, sometimes known as Chinese Violet, was found naturalised in Darwin in April 2015 and was immediately eradicated. Although cultivated as an ornamental, this plant is regarded as an invasive weed in eastern Australia where it has been established for 15 years, and is a recognised problem weed in neighbouring tropical countries. Identification and taxonomic aspects of this species are briefly discussed, as is its distribution in Australia and overseas, and its possible means of arrival in Darwin. Introduction Asystasia gangetica subspecies micrantha (Nees) Ensermu is a target weed species of the Northern Australia Quarantine Strategy which means that it has been identified as a plant that, if introduced, is likely to have substantial detrimental impacts on agricultural production and the environment. Asystasia gangetica subsp. micrantha is also on the Alert List for Environmental Weeds (Australian Government Department of Environment 2000), a list of non-native plants that threaten biodiversity and cause other environmental damage. Asystasia gangetica subsp. micrantha is a form of Chinese Violet and belongs to the large, predominantly tropical plant family Acanthaceae. It is a perennial herb that can grow in a mat-forming habit and smother more desirable ground plants, thus potentially affecting agriculture or reducing biodiversity.

The genus Saxicolella Engl. (Podostemaceae) are African rheophytes, restricted to rapids and waterfalls as are all members of the family. Previously, Saxicolella sensu lato was shown to be polyphyletic with two separate clades in the molecular phylogenetic study of Koi et al. (2012). The name Pohliella Engl. was recently resurrected for one clade that is sister to the American genera Ceratolacis (Tul.)Wedd., Podostemum Michx. and all Old World Podostemoideae (podostemoids) (Cheek 2020). Pohliella has distichous phyllotaxy, bilocular ovaries, filiform roots with paired holdfasts, and rootcaps. The second clade, Saxicolella sensu stricto, including the type of the generic name, has spiral phyllotaxy, unilocular ovaries, ribbon-like or crustose roots that lack both holdfasts and rootcaps. Saxicolella sensu stricto, sampled from the type species, S. nana Engl. of Cameroon, is embedded within and near the base of the major clade of African podostemoids and is sister to all other African genera apart from Inversodicraea R.E.Fr.
