A new Cheilolejeunea Marchantiopsida: Lejeuneaceae from montane forests in New Zealand

Abstract

Cheilolejeunea celata M.Renner & Glenny sp. nov., a minute species from high elevation (generally >600 m), high rainfall forests on the wetter, western side of New Zealand, is described and illustrated. It is similar to Cheilolejeunea novaezelandiae R.M. Schust. in its dome-shaped papillae on the lobe surface and its autoicous state, but differs in bearing papillae over the entire lobe surface and on the underleaves, in having narrower underleaves that are never imbricate and have a narrow sinus, and in growing primarily in forest, on the stems of other bryophyte species. In its combination of oblique lobes, strongly inflated keel, and bifid underleaves, the species provides further support for the recent merger of Cyrtolejeunea into Cheilolejeunea.

Two new endemic species of Ophiorrhiza L. (Rubiaceae: Ophiorrhizeae) from Davao Oriental,Philippines

Two new species of Ophiorrhiza collected from Mt Hamiguitan Range Wildlife Sanctuary in Davao Oriental, Philippines, are herein described and illustrated. Ophiorrhiza erythropilosa is the third Philippine species possessing involucral bracts and is further characterized by its predominantly villose stems that appear red due to strikingly red-violet trichomes, subpersistent bifid stipules, linear involucral bracts without prominent midrib, and 4 mm long urceolate corolla that is villose outside and lightly puberulous inside. Ophiorrhiza hamiguitanensis is characterized by its coriaceous, lanceolate leaves with attenuate apex and base, brochidodromous venation, subpersistent bilobed stipules with slightly recurved acute tips, presence of 1.5–2.5 mm long linear ensiform bracts, heterostylous flowers, clavate calyces and broadly obcordate capsules.

Primulina tsoongii sp. nov. (Gesneriaceae) is described and illustrated here. This new species resembles P. hochiensis and P. hochiensis var. rosulata, but is easily distinguished by its sparsely hirsute mature leaves, narrow bracts (only 0.4–0.5 in diameter) and undivided yellowish ligulate stigma with dense elongate papillae.

TWO NEW SPECIES OF MICROPLITIS FOERSTER (HY‐MENOPTERA: BRACONIDAE) FROM CHINA*

Abstract The present paper describes two new species of Microplitis Fcerster 1862, viz: Microplitis zhaoi Xu et He sp. nov. and Microplitis choui Xu et He sp. nov. The type specimens are deposited in Zhejiang University, Hangzhou, China. 1. Microplitis zhaoi sp. nov. is described from Fujian and Zhejiang Provinces in China closely related to Microplitis malimba Papp, but differs from the latter in the combination of the following features: 1) l‐R1 shorter than stigma; 2) sternites 1–3 yellowish white; 3) submarginal cell of hind wing 2 times as long as basal width and 4) r as long as 2‐SR. 2. Microplitis choui sp. nov. is described from Shaanxi and Gansu Provinces in China closely related to Microplitis zhaoi sp. nov. but differs from the latter in the combination of the following features: 1) r shorter than 2‐SR; 2) sternites 1–3 blackish: 3) tergites 2–3 black; 4) cu‐a of hind wing strongly sloped outward and 5) antenna shorter than body.     

Symplocos parvibracteata sp. nov. (Symplocaceae) from the Western Ghats,Kerala, India

Symplocos parvibracteata sp. nov. (Symplocaceae) from Chemunji Hills, south Western Ghats, Kerala State, India, is described and illustrated. It is most similar to S. wynadensis and S. tenella, a putative synonym of S. wynadensis, but differs in having shorter racemes, shorter bracts and bracteoles that are persistent in flower and caducous in fruit, narrowly ellipsoid flower buds, and fewer stamens per flower. It is also similar to S. sumuntia, from which it differs by its pubescent branchlets, generally more stamens per flower, and a pubescent floral disk, and to S. macrophylla, from which it differs by the combination of 3 to 5 leaf secondary veins on each side of the midvein, 1–2‐cm long inflorescences, and bracts that are persistent in flower, caducous in fruit, and < 1.5 mm long.     

Hepatics from Rovno amber (Ukraine), 6. Frullania rovnoi,sp. nov.

A fossil species of the extant liverwort genus Frullania Raddi is described and illustrated, based on a single inclusion in a piece of Rovno amber (Ukraine) that shares its age with Late Eocene Baltic amber, its northern contemporary. Frullania rovnoi is characterised by leaves with a rounded dorsal lobe and the absence of ocelli. The ventral lobe is inflated and forms a saclike lobule, which is bell-shaped and somewhat constricted above the mouth. The bifid underleaves have several blunt teeth or angulations along the shoulder. The Rovno fossil differs sufficiently from morphologically similar species preserved in Baltic and Bitterfeld amber as to be described as new to science. The shape of the lobules and underleaves, as well as the absence of ocelli, indicate an affiliation to F. sect. Australes, hitherto represented in Eocene amber inclusions solely by F. schumannii (Casp.) Grolle. The Rovno fossil is distinguished from extant species of F. subg. Australes and from F. schumannii by having roughly and irregularly dentate-angulate underleaf margins.     

Frullania larjiana (Jungermanniopsida: Frullaniaceae), a new species from India

Abstract

Frullania larjiana Sushil K. Singh & Singh is described as a new species from the Western Himalaya, India. The species is characterized by ovate-suborbicular leaf lobes that are truncate at their antical bases; uniformly lanceolate–explanate lobules, 0.15?0.17 × 0.0?0.09 mm with a vestigial stylus 1–2 cells long; small underleaves, 0.16?0.3 × 0.1?0.15 mm; obovate to oblong-obovate female bract lobes; triangular lanceolate bract lobules without a stylar tooth and an obovoid, smoothly 5-keeled, shortly beaked perianth.     

Two new species of Microlicia D.Don (Melastomataceae) from campos rupestres in eastern Brazil

Two new species of Microlicia (Melastomataceae) endemic to campos rupestres in Serra do Cipó, Minas Gerais, Brazil, are described, illustrated and compared with their putative relatives. Microlicia rugosa sp. nov. is similar to M. minutiflora and M. martiana by having fastigiate branches, ascending, lanceolate or oblanceolate leaves with obtuse apex, attenuate base and entire margin, flower with short pedicels (1?2 mm long), magenta petals, and dimorphic stamens. Microlicia rugosa is further characterized by wrinkled surface of hypanthium and sepals, and both leaf surfaces with distinct depressions, which sometimes contain short‐stalked glandular trichomes. Microlicia viscida sp. nov. is similar to M. martiana, M. furnensis and M. rugosa mainly by having fastigiate branches, terete stems without leaves at the base and the bark gradually peeling to reveal the underlying brownish wood and leaves with similar size and shape. Microlicia viscida is characterized by a conspicuous secretion covering branches, leaves, hypanthium and sepals, giving a smooth and bright appearance. The leaf anatomy of both new species is briefly described. Microlicia rugosa and M. viscida are assessed as ‘Endangered’ and ‘Critically Endangered’ respectively, due to its limited extent of occurrence and area of occupancy, according to the IUCN categories and criteria.     

New costapalmate palm leaves from the Oligocene Ningming Formation of Guangxi,China, and their biogeographic and palaeoclimatic implications

New palm leaves from the Oligocene Ningming Formation are placed into the morphogenus Sabalites because of their costapalmate leaf shape. Four taxa are described on the basis of leaf compressions with cuticular structure. S. guanxiensis sp. nov. is characterised by hypostomatic leaf blades with a stout costa and a symmetrical base. Sabalites cf. asymmetricus has amphistomatic leaf blades with a long, delicate costa and an asymmetrical base. Sabalites sp. 1 has amphistomatic leaf blades with a long, massive costa and wide segments. Sabalites sp. 2 is characterized by hypostomatic leaf blades with a prominent costa and an asymmetrical base. The four new palm taxa expand our understanding of the floristic elements and features of the Oligocene Ningming flora. Together with the other three palm taxa that were previously reported from the Ningming Formation, our material indicates that the Oligocene Ningming flora had a rich diversity of costapalmate palms. The relatively high species diversity of palms and other plants corroborate that the Oligocene Ningming flora represents a warm and humid climate.
