Abstract
Lappula effusa D.H.Liu & W.J.Li, a new species of Boraginaceae from Xinjiang, China, is described and illustrated in this study. The new species is morphologically similar to Lappula himalayensis and L. tadshikorum. However, it can be distinguished from the compared species by several characteristics, such as: stem single, erect, frequently branched at middle and above, densely spreading hispid, hairs discoid at base; corolla white or blue; fruit compressed, heteromorphic nutlets with two rows of marginal glochids, nutlets acute ovoid, disc narrowly ovate-triangular. The diagnosis of the new species is supported with comprehensive investigation including photographs, detailed description, notes on etymology, distribution and habitat, conservation status, as well as comparisons with morphologically similar species.

Lappula effusa D.H.Liu & W.J.Li, sp. nov.
Diagnosis: The new species is morphologically similar to Lappula himalayensis and L. tadshikorum, but differs from the L. himalayensis primarily in the following characteristics: stem single (vs. stems 4–6, cespitose), erect (vs. ascending or erect), frequently branched at middle and above (vs. branched above), densely spreading hispid, hairs discoid at base (vs. densely appressed pubescent); corolla white or blue (vs. blue); fruit compressed (vs. ...
Etymology: The specific epithet refers to the appearance of new species, stems frequently branched at middle and above and nearly horizontal spreading.
