2017 40(1) 4-28 Sin Yeng Wong, Aisahtul binti Wardi, Peter C. Boyce Studies on Schismatoglottideae (Araceae) of Borneo LX: Preliminary notes on the Schismatoglottis Patentinervia Clade, including descriptions of three new species (Buy)
ABSTRACT: A review of the Schismatoglottis Patentinervia Clade is presented. Six species are accepted, of which three are pre-existing – Schismatoglottis patentinervia Engl. (Kalimantan Barat: Melawi), S. pectinervia A. Hay (NE Sarawak: Mulu; Brunei) and S. retinervia Furtado (Sabah: Kinabalu) – and three are taxonomic novelties: S. belonis S. Y. Wong, Aisahtul & P. C. Boyce (C Sarawak: N & C Kapit), S. gaesa S. Y. Wong, Aisahtul & P. C. Boyce (Kalimantan Utara: Malinau), and S. smaragdina S. Y. Wong, Aisahtul & P. C. Boyce (C Sarawak: N Kapit). Morphological delimitation of the Patentinervia Clade is provided, all species are described and illustrated from living plants and pre-existing species also figured from their nomenclatural Types. An identification key is offered.

2017 40(1) 29-38 Sin Yeng Wong, Peter C. Boyce Studies on Schismatoglottideae (Araceae) of Peninsular Malaysia I: On the identity of Schismatoglottis wallichii var. oblongata and a new name: Schismatoglottis lowae (Buy)
ABSTRACT: Schismatoglottis lowae S. Y. Wong & P. C. Boyce sp. nov. is described and illustrated based on the type of Schismatoglottis wallichii var. oblongata Hook.f., until now treated as a heterotypic synonym of S. wallichii Hook.f. A key to the three accepted species of hapaxanthic-stemmed (Calyptrata Clade) Schismatoglottis in Peninsular Malaysia is provided.

2017 40(1) 39-56 Wendy A. Mustaqim, Nisyawati Aroids of southern Mount Lawu, Central Java: an ever-wet island in a seasonal region of Java (Buy)
ABSTRACT: A recent exploration for aroids has been conducted in the ever-wet southern part of Mount Lawu, Central Java, Indonesia. Six species belonging to six genera have been recorded. The geographical distribution of Leucocasia gigantea in Central Java is expanded to the southern part. Keys, descriptions and figures are given for all species.

2017 40(1) 57-62 Van Tien Tran, Van Du Nguyen, Cong Sy Nguyen Biological Characteristics and Distribution of the species Amorphophallus yuloensis H. Li (Araceae) in Vietnam (Buy)
ABSTRACT: The paper includes information on the ecology and biology, distribution and content of glucomannan in tubers of the species Amorphophallus yuloensis H. Li in Vietnam. Amorphophallus yuloensis belongs to a group in the genus with short peduncles. It differs from other species in the group by having a much smaller inflorescence, stout conical appendix and violet blue berries. This is one of five species in Vietnam whose tubers contain high glucomannan content for the food industry. Glucomannan content in its tuber is about 29.2% of dried weight.

2017 40(1) 63-70 Lalleima Chakpram, Yumkham Sanatombi Devi, Potsangbam Kumar Singh Colocasia oresbia (Araceae) – An Addition to the Flora of India (Buy)
ABSTRACT: Colocasia oresbia A. Hay is reported for the first time from India from its Northeast state Manipur. The detailed morphology of the collected specimen, an SEM image of the pollen and photographs of the live specimen are presented.

2017 40(1) 71-83 M. Chartier, Jean-Loup Fernandez, David Prehsler, Jürg Schönenberger, Marc Gibernau Note on the pollination of Calla palustris L. (Araceae) (Buy)
ABSTRACT: Calla palustris L., despite its wide distribution in the Northern Hemisphere, is poorly understood with respect to its ecology. We made observations on the flowering sequence and on floral visitors in a natural population in the Vosges, France, and conducted mating system experiments in the Botanical Garden of the University of Vienna. The anthesis of Calla inflorescences lasted approximately ten days. It started by a female phase with stigmas becoming receptive from the base to the top of the inflorescences. Stamen dehiscence followed the same pattern and the male phase started towards the end or after completion of the female phase. Our experiments showed that Calla is at least partly self-pollinated or apomictic, as ca. 20 % of the gynoecia developed into fruits and produced seeds without pollinators. Entomophily cannot be excluded, as we observed few small Coleoptera and Diptera visiting the inflorescences. Anemophily, although less probable, remains to be tested.

2017 40(1) 84-96 Nathan Hartley, Thorsten Krömer, Marc Gibernau Lepidopteran visitors of Anthurium inflorescences (Buy)
ABSTRACT: Observations on the pollination biology of the genus Anthurium are scant in comparison to other aroid genera despite comprising nearly 33% of all aroid species. Here we report two independent observations of lepidopteran visitors in two species of Anthurium. In Costa Rica, two different species of fruit-piercing moths (Erebidae) were observed visiting two separate individuals of A. caperatum in pistillate anthesis at night; however, no evidence for pollen vectorization was obtained. In Mexico, several individuals of the 88-butterfly (Diaethria anna; Nymphalidae) were observed visiting A. podophyllum during the middle of the day. Additionally, pollen of A. podophyllum was observed deposited on the ventral abdomen of an 88-butterfly. These findings, although lacking the data needed to confirm their role as pollinators of these Anthurium, are significant in that they represent the first documentation of lepidopteran visitors for any species of aroid. A review of spadix secretions in Anthurium is also provided and an encouragement to augment the number of studies on pollination biology of this genus is offered.

2017 40(1) 97-116 Thomas B. Croat, David Belt, Jere Deal New species of Anthurium sect. Calomystrium (Araceae) from Mexico and Panama (Buy)
ABSTRACT: A total of four new species of Anthurium section Calomystrium from Mexico and Panama are described here: A. totontepecense Croat from Mexico and A. hartmanii Croat, A. mikeneei Croat, and A. viridifusiforme Croat, all from Panama.

2017 40(1) 117-149 Thomas B. Croat, Robert Hormell New Central American Species of sect. Andiphilum (Araceae)- the Anthurium silvigaudens Standl. & Steyerm. Complex (Buy)
ABSTRACT: Three closely related species in the newly resurrected section Andiphilum are described and two of them which are new to science are described and compared. The Anthurium silvigaudens complex is restricted to Middle America (Honduras and Guatemala).
