Aim of study: In the present study, Acalypha brachystachya Hornem. (Euphorbiaceae) is recorded to the vascular flora of Türkiye from NE Anatolia for the first time, as a neophyte. Area of study: Research and application greenhouse of Forest Faculty, Karadeniz Technical University (KTU) in Trabzon province, Türkiye.Material and method: Studied materials of A. brachystachya were collected from the pots in KTU propagation and research greenhouse in Trabzon province located in NE Anatolia. All specimens were stored at KATO (in Karadeniz Technical University, Faculty of Forestry) Herbarium.Main results: A. brachystachya is reported from propagation and research greenhouse as a new alien species for the vascular flora of Türkiye.Research highlights: A greenhouse weed, second alien species of the genus Acalypha in Türkiye, reported here which has not been reported yet from Türkiye prior to the present paper. It is estimated that it was unintentionally carried to Türkiye by the pot soil. Though its large natural distribution, A. brachystachya was only reported from Canary Islands and Europe (South Italy and Hungary) as alien species before the present report. The species has not hitherto been reported as invasive. However, it has been reported from greenhouse in Anatolia (present study), garden and nursery material in Europe. Therefore, the authors recommend monitoring the species where it has been detected in Türkiye.
