VERDCOURT Summary. Ascarina subsessilis is described as new and three new combinations are made in Sarcandra and Chloranthus. A summary of the literature dealing with the systematic position of the family is given. Whilst preparing an account of the Chloranthaceaefor Flora Malesiana some difficulty was experienced in delimiting the taxa of Ascarina. Examination of the extensive material at Leiden showed that some specimens from the high- land area of Papua New Guinea were distinctly different in foliage from A. philippinensis C. B. Rob. with which they had been confused; these have been ascribed to a distinct species which is described below. Ascarina subsessilis Verdc. sp. nov. affinis A. philippinensis C. B. Rob. sed foliis subsessilibus carnosioribus satis distincta. Typus: Papua New Guinea, Western Highlands, Hoogland & Schodde 7331 (holotypus L; isotypi CANB, E, K).

Male structure with non-antheriferous part very reduced or absent, i.e. the anther cell more or less as long as the structure. DISTRIBUTION.S China to NE India and throughout Malesia from Malaya to Papua New Guinea. When Swamy & Bailey (1950) dealt exhaustively with the anatomy of Sarcandra and reinstated the genus they treated Chloranthusbrachystachys as a synonym of Sarcandraglabra but kept up S. hainanensis (Pei) Swamy & Bailey stating that it had discoid male structures with the anther cells as long as or almost as long as the whole structure and also gave a number of other charac- ters, including anatomical, of little actual taxonomic significance. Typical S. glabra from Japan and northern China has the non-antheriferous part of the male structure quite well-developed. Dr Ohashi has kindly informed me that an examination of Japanese material shows little variation in the relative lengths of the anther-cells and the non-antheriferous part although there is a gradation in size from north to south. Chinese material I have examined supports this. All tropical material of S. glabra has the structure very similar to that depicted for S. hainanensisand I consider subspecies should be recognized. The anomaly of having a species widespread in Malesia and Asia save in Hainan is therefore eliminated; rather there is a tropical subspecies extending to S China and a more northern subspecies. The occurrence of some slightly intermediate specimens in northwest India and probably in China suggests that specific rank is not correct; if it were so decided the epithet serratawould have to be employed. It is clear from the Flora Yunnanica (1: 21 (1977)) that NOTES ON MALESIAN CHLORANTHACEAE 217 both S. glabra and S. hainanensisare considered to occur there but C. brachystachys is still placed in the synonymy of the former.

Photographer: Bec Stanley 2012 | At Risk – Naturally Uncommon | Qualifiers: IE, OL PREVIOUS CONSERVATION STATUSES 2009 | At Risk – Naturally Uncommon | Qualifiers: IE, OL 2004 | Not Threatened BRIEF DESCRIPTION Small bushy tree of upland Kermadec Islands. Leaves narrow and tapering to a narrow tip and with coarse black- tipped teeth on margins. Flowers in clusters of spikes. Fruit small, white. DISTRIBUTION Endemic. Kermadec Islands, Raoul Island only. HABITAT One of the characteristic trees of the wet forests of Raoul Island which are mostly found above 245m. However, in the ravines this tree may extend down to almost sea level. In the wet forest it is mostly a subcanopy tree which co- associates with Coprosma acutifolia, Pseudopanax kermadecensis, Melicytus aff. ramiflorus and on occasion Boehmeria australis subsp. dealbata. Occasionally, such as on the ridge lines and crater rim it may form part of the forest canopy. FEATURES Glabrous gynodioecious tree up to 15 m tall. Trunk up to 500 mm diameter. Bark greyish-white. Branchlets slender, striate, initially pale green maturing dark green to emerald green. Interpetiolar stipules conspicuous, comprising 3 1.2-2.6 mm long pale pink to red, filaments; these connate near base, behind which are 3-6 smaller hyaline filaments. Petioles up to 15-20 mm long, lamina subcoriacous, somewhat fleshy, 50-100 × 10-30 mm, green, emerald green to dark green above, paler beneath, serrations weakly pigmented, pink to pale maroon often fading into pale pink spotting, narrowly lanceolate, lanceolate, lanceolate- oblong to narrowly elliptic, acuminate to acute.

Methods Now Chinese Journal Full-text Database (CNKI), Chinese Biomedical Literature Database (CBM), Wanfang database and VIP database aggregated from 1994 to the relevant literature and 2009, and summarized Sarcandrae anti-tumor effect and mechanism; l platelets, leukocytes , enhance the immune effect. Results Herba Sarcandrae significant anti-tumor effect and its mechanism of inducing apoptosis; Herba Sarcandrae can be increased platelets, white blood cells, enhance immunity. And chemotherapy drugs increase the discharge rate when combined with anti-tumor chemotherapy drugs, reducing its toxicity to blood and immune system. Conclusion Herba Sarcandrae inhibitory spectrum, low side effects, is widely used in clinical practice, there is a good prospect. Introduction Herba Sarcandrae to Chloranthaceae plant grass coral [Sarcandra glabra (Thunb1) Nakai] the whole plant. Herba Sarcandrae, alias grass coral, sarcandra, bone Chloranthus etc., only contained in the "herbal medicine prepared to be."

For blood heat purpura, purpura, rheumatism, bruises. Modern pharmacological studies have shown that Herba Sarcandrae has analgesic, anti-inflammatory, anti-tumor, promote healing, and other activities. In this paper, a review of Chinese Journal Full-text Database (CNKI), Chinese Biomedical Literature Database (CBM), Wanfang database and VIP database from 1994 to 2009 literature on Sarcandrae anti-tumor effect and mechanism related summarized.

  • The Pakihi Bog Began As a Lake When the Surrounding Area Was Forested by Both Podocarps and Silver Beech
    76 PROCEEDINGS OF THE NEW ZEALAND ECOLOGICAL SOCIETY, VOL 22, 1975 A LOWLAND VEGETATION SEQUENCE IN SOUTH WESTLAND: PAKIHI BOG TO MIXED BEECH-PO DO CARP FOREST PART 1: THE PRINCIPAL STRATA A. F. MARK and P. M. F. SMITH Botany Department. University of Otago. Dunedin, New Zealand SUMMARY: Six stands of lowland vegetation representing transitions from pakihi bog to mixed beech-podocarp forest are described quantitatively from the coastal plain of the Arawata and Jackson Rivers in South Westland. The sequence depicts progressive changes in canopy height. biomass and floristic richness. and appears to involve, at least in part. a primary succession. Some boundaries have been sharpene:i by periodic fires but the long+ term trend remains unobscured. Pollen evidence indicates that the pakihi bog began as a lake when the surrounding area was forested by both podocarps and silver beech. The bog seems never to have supported a \'.'oo:l.y vegetation but in the absence of fire. forest would slowly encroach on it. With a highway traversing the sequence. its reservation for educational and scientific pur~ poses has been proposed.
