Abstract
Abstract Helianthus grosseserratus M. Martens was first recorded in Lithuania in 2014. Rather large population of this species was found in Siauliai district (northern Lithuania), in the vicinity of Bridai village, on the territory of recultivated former municipal dump. This species can be easily distinguished from other perennial Helianthus species by glabrous stem, long, serrate, alternate leaves on the upper part of the stem and spindle-shaped roots. Supposedly, H. grosseserratus was brought to the area with garden waste or soil used for dump recultivation about 30 years ago and recently it has established in the locality. In the investigated capitula, no developed seeds were found. H. grosseserratus reproduces vegetatively by rhizomes and under favourable conditions can survive for a long time.
摘要2014年首次在立陶宛记录到太阳花(Helianthus grosseserratus M. Martens)。在Siauliai地区(立陶宛北部)Bridai村附近，在重新开垦的前市政垃圾场的领土上发现了相当大的种群。本种与其他多年生向日葵属植物有明显区别，茎无毛，茎上部叶长，有锯齿，互生，根呈纺锤状。据推测，大约30年前，随着花园废弃物或用于垃圾场再耕作的土壤，粗叶红被带到该地区，最近在当地扎根。在调查的头状花序中，未发现发育的种子。毛茛通过根状茎营养繁殖，在有利条件下可以长时间存活。
