本文记述了湖北、湖南一新种大老林Ligularia dalaolingensis。它属于L.门。基于其掌状叶脉，总状共花序和比管状花冠的筒部稍短的冠部的物种。在这个系列中，它的近亲被认为是L. fischeri和L. stenocephala。从费雪属来看，达洛林属很容易区分为基生叶较小，同花期较短，总苞较窄，叶节和小花较少；不同的是，它的基生叶较小，同花期较短，苞片较宽。标题中国血吸虫种诊断关键字。种皮具宽卵形，卵形或卵形披针形的苞片。
Ligularia dalaolingensis, a new species from Hubei and Hunan, China, is described and illustrated. It belongs to L. sect. Ligularia ser. Speciosae on the basis of its palmate leaf venation, racemose synflorescence and pappus which is slightly shorter than the tube of the tubular corolla. In the series, its closest relatives are assumed to be L. fischeri and L. stenocephala. From L. fischeri, L. dalaolingensis is readily distinguished by smaller basal leaves, shorter synflorescence, narrower involucres and fewer phyllaries and florets; from L. stenocephala, L. dalaolingensis differs by smaller basal leaves, shorter synflorescence as well as broader bracts. A diagnostic key to Chinese species of L. ser. Speciosae with broadly ovate, ovate or ovate-lanceolate bracts is provided.
