Bulbophyllum ningboense, a new species of Orchidaceae from Zhejiang, China

doi: 10.11833/j.issn.2095-0756.2014.06.004

Abstract: A new species of Ochidaceae, Bulbophyllum Thou., B. ningboense G. Y. Li ex H. L. Lin et X. P. Li from Fenghua County of Zhejiang, China is described in this paper. The new species is morphologically similar to B. chrondriophorum (Gagnep.) Seidenf., but differs in having pseudobulbs close to each other or apart from; leaves 12.0-15.0 mm long; scape obviously longer than blade, a joint with one membranous cybmo-sheath at mid-lower part of scape; lateral sepals 8.0-9.0 mm long; dorsal sepal ovate-lanceolate, 3-veined; dorsal sepals and petals glabrous at margin; petals ca. 2.0 mm long.

  • 石豆兰属Bulbophyllum Thou.为兰科Orchidaceae附生植物,全球约有1 000种,主要分布在亚洲、美洲、非洲、大洋洲等热带及亚热带地区。中国有98种3变种,分布于长江流域及以南各省、区[1];浙江产4种[2-3]。在2012年开始的宁波市植物资源调查中,作者在浙江省奉化市溪口镇岭下村丹霞地貌海拔约为100 m的岩壁上发现了1种石豆兰,经文献查证[1-7]及专家鉴定,确认该种石豆兰为1新种。

Seidenf., but differs in having pseudobulbs close to each other or apart from; leaves 12.0-15.0 mm long; scape obviously longer than blade, a joint with one membranous cybmo-sheath at mid-lower part of scape, lateral sepals 8.0-9.0 mm long; dorsal sepal ovate-lanceolate, 3 veins; dorsal sepals and petals glabrous at margin; petals ca. 2.0 mm long. In contact, the pseudobulbs of B. chrondriophorum (Gagnep.) Seidenf. apart from each other; leaves 1.5-3.5 cm long; scape almost as same long as leaf, no joint and membranous sheath; lateral sepals 7.0-25.0 mm long; dorsal sepal ovateoblong, 5 veins, margins except base with densely glandular-papillate appendages; petals 3.0-4.0 mm long, margins densely with glandular-papillate appendages.

    附生兰。根状茎匍匐,纤细,直径约为1.0 mm。全体无毛;假鳞茎卵球形,长为5.0~6.0 mm,粗4.0~5.0 mm,具6~8棱,在根状茎上紧靠或分离着生,分离者彼此相距6.0~10.0 mm,顶生1叶。叶片硬革质,长圆形,长为12.0~15.0 mm,宽6.0~8.0 mm,先端圆钝且微凹,基部圆形,中脉明显,在上面显著凹陷,几无柄。花葶从假鳞茎基部抽出,光滑,细长,绿色,远长于叶片,长为2.5~3.5 cm,基部具3~4枚膜质鞘,花葶中部以下有1个关节,关节上着生1枚膜质鞘,鞘舟状;伞房状花序有花4~5朵;每花梗具1枚长为1.0~2.0 mm的披针形苞片;苞片黄色,膜质;花梗连同子房长约1.5 cm,全体黄色;花黄色;中萼片卵状披针形,长为4.0~5.0 mm,宽约为2.5 mm,全缘,先端渐尖,具3脉,2枚侧萼片长为8.0~9.0 mm,宽约为3.0 mm,中上部内卷成筒状并靠拢,直伸或稍弯曲,全缘,先端钝尖;花瓣宽卵形,长约为2.0 mm,宽约为1.5 mm,先端圆钝,具3脉;唇瓣厚舌状,肉质,长约为4.0 mm,橙红色,先端圆,基部弯曲,具关节,与蕊柱足相连;蕊柱半圆柱形,长约为2.0 mm。花期5月,果未见。该种形态与城口卷瓣兰B. chrondriophorum相近,区别在于:该种假鳞茎在根状茎上紧靠或分离着生;叶较短,长仅为12.0~15.0 mm;花葶远长于叶片,中部以下有1个关节,关节上生有1枚膜质鞘;2枚侧萼片较短,长为8.0~9.0 mm,中萼片卵状披针形,具3脉,中萼片与花瓣边缘均无毛;花瓣长约为2.0 mm。城口卷瓣兰假鳞茎在根状茎上分离着生;叶长为1.5~3.5 cm;花葶与叶近等长,无关节与膜质鞘;侧萼片长7.0~25.0 mm,中萼片卵形,具5脉,边缘除基部外密生腺状突起物;花瓣长为3.0~4.0 mm,边缘密被腺状突起物[4]
