独蒜兰

独蒜兰（Pleione bulbocodioides）为兰科独蒜兰属多年生草本植物。陆生兰,一般株高15～25 cm,多分布于中国长江流域及其以南的地区,海拔630～3 000 m的密林下或沟谷旁有泥土的石壁上常见大片野生分布。独蒜兰属植物全球约16种,中国分布有15种。根据1999年国家林业局农业部第4号令批准的《国家重点保护野生名录（第1批）》,     

独蒜兰种子共生萌发研究

采用从独蒜兰分离的菌根真菌与其种子在燕麦培养基上共生萌发。结果表明GN21、GN23和GN24的作用效果较好, 其中GN21萌发率84.6%, 高于对照7个百分点, 达到显著性。同时也表明, 从同一兰科植物分离到的属于同一属的不同菌根真菌种, 有的能明显促进种子萌发, 有的却不能促进萌发, 甚至产生病斑, 引起原球茎死亡。

中国兰科杓兰属一新种及一新变种

对云南东南部兰科新种麻栗坡杓兰(Cypripodium,malipoense)和新变种大围山杓兰(Cypripedium lichiangense var.datveishanense)作了描述。麻栗坡杓兰与文山杓兰(C.lentiginosum)相近,区别点在于新种叶淡黄色而有紫斑,色泽与花瓣及唇瓣极为相似;花瓣明显较短,仅稍长于唇瓣。新变种大围山杓兰与原变种的不同在于中萼片黄绿色,疏生紫红色斑点;花瓣仅稍长于唇瓣;唇瓣囊口有一黑色圈。     

深圳拟兰，中国兰科一新种

对兰科新种深圳拟兰（Apostasia shenzhenica Z.J.Liu＆L.J.Chen）作了描述和绘图。该新种产中国广东南部,与多枝拟兰（A.ramifera S.C.Chen＆K.Y.Lang）和日本拟兰（A.nipponica Masamune）相近,但本新种的根生有块根;退化雄蕊明显长于花柱,而且上部约1/3不贴生于花柱,可以区别。     

中国云南兰科一新种——昌宁兰

对产于中国云南昌宁的兰科新种昌宁兰(Cymbidium changningense)作了描述与绘图。     

独龙虾脊兰（兰科）的合格发表

通过补充拉丁文描述和指定模式,本文合格发表了独龙虾脊兰Calanthe dulongensis H. Li, R. Li & Z. L. Dao。该种因其唇瓣中裂片上有3个具短柄的金黄色球状附属物而有别于本属的其他类群。本种在体态上与疏花虾脊兰C. henryi Rolfe和车前虾脊兰C. plantaginea Lindl.相近,不同之处在于本种的根状茎明显,花瓣倒卵状披针形 ,中萼片无毛;本种在体态上也与三褶虾脊兰C. triplicata (Willem.) Ames相近,区别在于本种的唇

Sirindhomia, a new orchid genus from Southeast Asia

The new orchid genus Sirindhomia , named after H. R. H. Princess Maha Chakri Sirindhorn of Thailand, is established to accommodate three species from Thailand (Chiang Mai and Tak provinces), Myanmar (Shan State), and China (Yunnan province). Two new species are described and a new combination, based on Habenaria monophylla Collett & Hemsl., is made; all of the three species are illustrated, and a distribution map is provided. Sirindhomia belongs to subtribe Orchidinae and has an overall similarity with Ponerorchis, Hemipilia , and Amitostigma. However, it significantly differs in its column morphology which is more reminiscent of that found in the vegetatively distinct genus Orchis. The new species, Sirindhomia pulchella and S. mirabilis , seem to be local endemics, as they are only known from the Thai mountains Doi Chiang Dao and Khao Hua Mot, respectively. Sirindhomia monophylla , on the other hand, is known from a very large part of the range of the genus. All Sirindhomia species known are restricted to limestone mountains at 800–2200 m alt., mainly growing in rock crevices and among scrub as well as on grassy slopes. They flower from April to June.     

Gavilea gladysiae (Chloraeeae: Orchidaceae), a new orchid from southern Argentina and Chile

A new species, Gavilea gladysiae, is described and illustrated. This rare species inhabits the humid forests of Santa Cruz (southern Argentina) and the Magellan region (southern Chile). This species has been mistakenly identified as Gavilea kingii in herbarium collections and previous floristic works.     

Ceratostomella hyalocoronata, a new pyrenomycete from a stream in southern China
