A new recorded family of plant from Zhejiang Province found in Ningbo:Philydraceae

doi: 10.11833/j.issn.2095-0756.2014.06.024

Abstract: A new record species Philydurm lanuginosum Banks et Sol. ex Gaertn. was found in Xiangshan, Ningbo, Zhejiang Province. This species, and its corresponding genus Philydrum Bands et Sol. ex. Gaertn. and the family Philydraceae are all new recorded. Its morphological characteristics, habitat, and usage were described. The voucher specimens are deposited in the plants herbarium of Zhejiang A & F University (ZJFC).

  • 笔者最近在浙江省宁波市植物资源调查过程中,于象山海边发现1种水生植物,经查阅相关文献[1-3],确定为田葱科Philydraceae的田葱Philydrum lanuginosum,且均未见浙江有该科植物分布的记载[4-5],为浙江科、属、种的分布新记录,现予以报道。

    多年生水生草本,高30~150 cm,主轴短,具纤维状须根。叶剑形,先端渐狭,等边单面,绿色,无毛,海绵质,柔软,具7~9脉,连叶鞘长30~80 cm;叶鞘长14~30 cm,宽1~1.5 cm,厚2~4 mm。总花轴高可达1 m,细长圆柱状,密被白色绵毛,下部脱落,通常带有2或3叶;穗状花序单一(图 1D),有时分枝;苞片卵形,长2~7 cm,宽7~10 mm,先端具尾状渐尖,背面有绵毛;花两性,黄色,无梗(图 1C);花被薄,外轮2片大,近卵形,长8~10 mm,先端锐尖,边缘波状,具2条强壮的脉向着基部,背面有长毛;内轮2片较小,近基部1~2 mm处与花丝基部联合,匙形,先端锐尖,无毛或背面基部有毛,膜质,具3脉;雄蕊无毛,长6~9 mm;花药近球形,2室,药室旋卷;花丝扁平;子房长6~7 mm,密被长毛;花柱长3~4 mm,无毛;柱头头状,具长乳突。蒴果三角状长圆形,长8~10 mm,近轴面扁平,密被白色绵毛。种子多数,花瓶状,中间膨大,两头近端处缢缩,至两端又扩大,长0.7~0.9 mm,暗红色,种皮上有螺旋状条纹。花期6-8月,果期9-11月。

    文献记载分布于福建、广东、海南、广西、台湾,多生于低海拔的池塘、沼泽或水田中。日本、越南、泰国、老挝、柬埔寨、缅甸、马来西亚、印度、巴布亚新几内亚、澳大利亚等国也有。

    中国(China),浙江(Zhejiang),象山(Xiangshan),松兰山(Songlanshan),山脚水边,海拔5 m,2013-04-09,G. Y. Li(李根有),D. D. Ma(马丹丹),Y. F. Zhang(张幼法) & Z. F. Yang(杨紫锋),XS201304024(果期,ZJFC);同地,2013-08-01,G. Y. Li(李根有),Z. H. Chen(陈征海),X. P. Li(李修鹏),D. D. Ma(马丹丹) & Y. F. Zhang(张幼法),XS2013080104(花期,ZJFC)。伴生植物主要有:石斑木Raphiolepis indica,中华绣线菊Spiraea chinensis,马甲子Paliurus ramosissimus,海滨木槿Hibiscus hamabo,链珠藤Alyxia sinensis,栀子Gardenia jasminoides,绵毛鹿茸草Monochasma savatieri,光萼茅膏菜Drosera peltata var. glabrata,芒Miscanthus sinensis,华克拉莎Cladium chinense,刺子莞Rhynchospora rubra,短柄粉条儿菜Aletris scopulorum,大花无柱兰Amitostigma pinguiculum等。

    来源考证:经访问景区及当地人员,均不认识该植物,也从未引种。从生境看(图 1),分布点地处被拦截的海湾边,位于景区隔离带之外,不属景区绿化范围,植株均生于岩缝或滩涂中,分布无规律,大小年龄不一致,能自播繁殖,且其周围伴生植物也均为野生种;从景区美化角度考虑,该种观赏价值不高,目前国内园林中几无应用,且在景区内也未见,故引种可能性极小。综上所述,该种应属野生无疑。

    本种可供药用,具清热解毒及化湿之效,可治水肿、热痹、疮疡肿毒、疥癣、脚气等症;也可用于水体绿化。
