Trichotosia gabriel-asemiana Mambrasar & Schuit., spec. nov. 

Diagnosis. This species is similar to Trichotosia microphylla Blume and T. dalatensis by its slender, creeping rhizome, short leaves (less than 2 cm long), and solitary flowers with an abaxial, conical callus near the lip apex. Trichotosia dalatensis has flowers that are similar in size and in the maroon colour, but differs in having a glabrous, uniformly thick lip with a distinct adaxial callus, whereas T. gabriel-asemiana has a lip that is sparsely pilose abaxially and which is abruptly divided into a fleshy basal part and a thin  textured upper part, but lacks an adaxial callus. Trichotosia microphylla has larger, yellowish green flowers (lip ca. 9 mm long, vs. 4 mm in T. gabriel-asemiana), with the lip not pubescent abaxially, and not abruptly divided into a fleshy basal part and a thinner upper part.

Etymology. Named in honour of Gabriel Asem, Regent of Tambrauw Regency since 2011, who in 2015 declared Tambrauw regency a conservation zone.

Abstract

A new species of Bulbophyllum (Orchidaceae: Bulbophyllinae) in section Macrocaulia from West Java, Indonesia is described as Bulbophyllum trinervosum Victoriano & Y.R.Yudistira spec. nov. This miniature orchid is found around Cakrabuana mountain range at an elevation of 1,300–1,550 m. The key characteristic of this species is unique among section Macrocaulia in having three nerves on its median sepal instead of five like the other species in this section.

Keywords: Bulbophyllum, Indonesia, Java, new species, orchids.

Bulbophyllum trinervosum Victoriano & Y.R.Yudistira, spec. nov.

 

Bulbophyllum trinervosum is similar to B. ovalifolium but differs in having a smaller flower, with three longitudinal veins on the median sepal (B. ovalifolium: five), an obovate lip with emarginate apex (B. ovalifolium: tongue-shaped, sub-acute apex) and oblong, oblique, folded petals each with one indistinct vein, the colour is identical to the lip (B. ovalifolium: oval–oblong and unfolded petals, with one distinctive vein, the colour is identical to the lateral sepals).

Etymology. From Latin trēs, the cardinal numeral of three for combination (tri-), and nervosus means sinewy or nerved. Thus, the epithet means three-nerved Bulbophyllum, it refers to the three longitudinal veins on the median sepal of this species.

Nepenthes harauensis Hernawati, R.Satria & Chi.C.Lee. spec. nov.

Nepenthes harauensis has several morphological characteristics similar to N. bongso, but the pitcher shape is more like the N. singalana. The most prominent distinguishing character is the thick and stiff coriaceous leaf structure, the peltate tendril insertion, and the sheath-like petiole, which clasps the stem for ¾– ½ of its circumference.

Distribution. Nepenthes harauensis is only known from the type locality in Harau, West Sumatra, Indonesia. 

 

Etymology. The specific name refers to the place “Harau,” a sub-district of Lima Puluh Kota Regency.

Begonia tjiasmantoi Ardi & D.C.Thomas spec.nov. 

§ Petermannia. 

Begonia tjiasmantoi has a rhizomatous stem, male and female flowers with yellow tepals and male flowers with relatively few stamens (22‒24). This character combination differentiates it from other Sulawesi Begonia species. The rhizomatous growth habit of Begonia tjiasmantoi is similar to the growth habit of the orange-tepalled B. ignita C.W.Lin & C.I.Peng, but B. tjiasmantoi can be differentiated by its strongly asymmetric, ovate toelliptic leaves (8–11 × 3.5–5.5 cm); cymose-paniculate male inflorescence with subumbellate partial inflorescences with up to 6 flowers; yellow male flower tepals that are relatively small (6–8 ×7.5–8.5 mm) and have few stamens (22–24);female flowers with shorter pedicels (3–4 mm), 5(–6) yellow tepals, and a cylindrical seed-bearing part of the fruit. Begonia ignita has symmetric or subsymmetric cordiform leaves that are larger (7–12 × 6.5–11 cm); racemose-cymose male inflorescence with monochasial partial inflorescences with up to 3 flowers; orange male flower tepals that are larger in size (10–15 × 9–11mm), more stamens (35–45); female flowers with longer pedicels (6–13 mm), 4 (or rarely 2, 3 or 5)orange tepals, and an ellipsoid seed-bearing part of the fruit. 

Etymology. The species epithet refers to Wewin Tjiasmanto, the Chairmain of the Tjiasmanto Conservation Fund, who has generously supported the Sulawesi Begonia Project.

 A new species of Nepenthes (Nepenthaceae) from Aceh Province, Indonesia, Nepenthes longiptera  Victoriano is herein described and illustrated. The species is unique among all other Nepenthes in  Sumatra by the presence of wings on its upper pitchers. Comprehensive description, photographs,  geographical distribution and preliminary IUCN conservation assessment are provided for the new species. Hybrids of this  new taxon with other species are also reported in this paper.  

Keywords: Nepenthes, carnivorous plant, Aceh, Sumatra, new species

Nepenthes longiptera Victoriano spec. nov. 
Vining plant with upper pitcher in locus classicus.  

Nepenthes longiptera Victoriano

Nepenthes longiptera is similar to N. tobaica but differs in having larger habit, with well developed upper pitcher wings (N. tobaica: reduced to ribs); rhomboid stem in cross-section (N. tobaica: obtusely triangular); and the presence of an appendage under the lid (N. tobaica: absent).

Etymology. From Latin longus means long and Latinised Greek pteron means wing; referring to the presence of a relatively long pair of wings of the upper pitchers, it runs down from below the peristome to the apex of the tendril. It is resembling the fins of Long-Finned Prickleback fish, Xenolumpenus longipterus Shinohara & Yabe

CONCLUSION: 

Nepenthes longiptera is a new species from Aceh, Sumatra, Indonesia. It is similar to N. tobaica but differs in having larger habit, with well developed wings on upper pitcher (N. tobaica: reduced to ribs); rhomboid stem in cross-section (N. tobaica: obtusely triangular); and the presence of an appendage under the lid (N. tobaica: absent). This new species is probably endemic to Aceh province and only known from Nagan Raya and Central Aceh Regency. It has several putative natural hybrids with other Sumatran species which are never been recorded in Aceh before. Some Acehense species such as N. lavicola, N. mikei and N. tobaica are abundant in highland forests but these species had been recorded with no hybrid with other species in this area (McPherson, 2009).

Rhododendron widjajae Argent & Mambrasar, spec. nov.

Diagnosis. Similar to Rhododendron pseudobuxifolium Sleumer in its size of flower. It differs in having twigs which are without the short hairs of that species; in having pedicels without simple hairs and the corolla is sparsely scaley outside not glabrous and glabrous inside, not shortly hairy. Superficially similar to R. celebicum (Blume) DC. but smaller and significantly differing from that species by the hairy filaments and ovary.

Habitat and ecology. Mt. Mekongga is a volcanic peak rising to 2,779 m in the north-west part of South East Sulawesi. This new species was collected in the sub-alpine area at 2,658 m asl. which is close to the summit (2,779 m). This area is described as: jagged limestone karst and the Rhododendron was probably an epiphyte. The associated species have not been recorded but will no doubt have been semi-open dwarf shrubs.

Etymology. Named in honour of Prof. Elizabeth A. Widjaja, former senior researcher at the Herbarium Bogoriense and joint collector of this species for her contribution to Indonesian botany.

Three additional species (Etlingera cylindrica A.D.Poulsen, E. grallata A.D.Poulsen, E. spinulosa A. D.Poulsen) were documented in this national park and represent new records for West Sulawesi Province. We also update information on the morphology of E. calobates A.D.Poulsen, correct an error in the typification of Alpinia chrysogynia (K.Schum.) K.Schum. and discuss the distribution of the Achasma Group of Etlingera east of Wallace’s Line.

Keywords: DNA barcoding, Etlingera calobates, E. mamasensium, E. megalocheilos, Indonesia, Zingiberales.

Etlingera mamasarum A.D.Poulsen & Ardiyani, spec. nov.

Type: Indonesia, West Sulawesi Province, Mamasa, Rantepongko Village, Gunung Gandangdewata, ..., 1,642 m, flowering and fruiting, 21 April 2016, M. Ardiyani with W. Santoso, Obet, Ama, A. Kartonegoro, D. Wulansari Sulbar 004 (Holotype: BO!; iso E!), Fig. 1, 2 & 3. DNA barcoding in Table 2. 

Diagnosis. Similar to Etlingera flexuosa A.D. Poulsen but differs in the length of the flowers which are shorter than the bracts, the longer petiole (45–55 mm in E. mamasarum vs 10–40 mm in E. flexuosa), the length to width ratio of the lamina (3.5–4 vs 4.2–5.6), the shape of the base of the lamina (rounded to cordate vs cuneate to auriculate), the size of the fertile bract (5.5−7 × 2.5−3.3 cm vs 2–5 × 0.6–2.5 cm), the position of the pedicel (4 mm stalk above the bracteole vs 1–4 mm below bracteole), the longer bracteole (3.6 cm vs 1.7–3 cm), the apices of the calyx spreading laterally to opposite sides of the flower (vs pointed straight forward), and the shape and size of the labellum (unevenly panduriform, 20–21 × 16 mm vs ovate, 17–22 × 14–20 mm).

Distribution. So far known only from the type locality at Gunung Gandangdewata. 

Habitat & Ecology. Grows in primary forest on a moderate slope not far from river at about 1,700 m. 

Etymology. The epithet honours the people of Mamasa, West Sulawesi, where the new species was found.

Local name & uses. Katimbang (Mamasa language), fruits are eaten.

Jenis baru Etlingera mamasarum A.D.Poulsen & Ardiyani telah ditemukan di Taman Nasional Gunung Gandangdewata, Sulawesi Barat. Jenis baru ini mirip dengan Etlingera flexuosa A.D.Poulsen tetapi berbeda dalam karakter bunga yang lebih pendek dari braktea. Jenis baru tersebut dipertelakan, diilustrasikan dan dilakukan barkoding DNA. Tiga jenis lainnya (Etlingera cylindrica A.D.Poulsen, E. grallata A.D.Poulsen, E. spinulosa A.D.Poulsen) telah didokumentasikan dan merupakan rekaman baru untuk provinsi Sulawesi Barat. Informasi morfologi E. calobates A.D.Poulsen telah diperbaharui, kesalahan tipifikasi Alpinia chrysogynia (K.Schum.) K.Schum. telah dikoreksi dan informasi persebaran E. megalocheilos (Griff.) A.D.Poulsen di timur garis Wallace didiskusikan dalam tulisan ini.
