03A987E2FFEBC85937A9FF08885FFCC1.taxon	discussion	Discussion: — Elatostema celingense is most similar to Elatostema backeri Schroeter (1936) from which it can be distinguished based on stem, stipule and staminate receptacle major bract morphology as summarised in the table below: Conservation status: — A Global Conservation Assessment is presented here based on IUCN methodology (2001, version 3.1). Elatostema celingense is known from a single locality (IUCN criteria D 2). At this locality the population of this species comprises ca 10 mature individuals (IUCN criteria D 1). The cave in which this species is located is at the edge of agricultural land on a small limestone hill, which, although deforested in the past, appears not to be actively disturbed. Using the IUCN methodology our Global Conservation Assessment for E. celingense is Critically Endangered (CR) based on criteria D 1 and D 2: population size and number of locations combined with a plausible future threat that could drive this taxon to Extinct in a very short time. Future threats include the use of caves in agriculture to store livestock or cultivate medicinal plants, mining of the limestone hills or tourism.	en	Wei, Y. G., Monro, A. K., Wang, W. T.

03A987E2FFE5C84F37A9FF7C8A66FDEE.taxon	discussion	Discussion: — Elatostema multicaule is most similar to Elatostema asterocephalum Wang (1980) from which it can be distinguished based on leaf, stipule and pistillate inflorescence morphology as summarised in the table below: Conservation status: — A Global Conservation Assessment is presented here based on IUCN methodology (2001, version 3.1). Elatostema multicaule is known from only two localities (criteria D 2). At each locality the population of this species numbers ca 100 mature individuals (criteria D 1). Plausible future threats that could drive this taxon to Critically Endangered or Extinct in a very short time are mining of the hills in which the caves are located or the use of caves in agriculture to store livestock / cultivate medicinal plants, or tourism. Using the IUCN methodology the Global Conservation Assessment for E. multicaule would be Endangered (EN) according to criteria D. We do, however, acknowledge that given the distance separating the known localities for this species that it is likely that there remain as yet undiscovered populations of this species. For this reason we downgrade the assessment to Vulnerable (VU) based on criteria D 1 and D 2.	en	Wei, Y. G., Monro, A. K., Wang, W. T.

03A987E2FFF8C84C37A9FD8C8F39FBFD.taxon	discussion	Discussion: — Elatostema nianbense is most similar to E. filipes Wang (1980), from which it can be distinguished based on its sexual system, stems, leaves, staminate inflorescences and flowers, and pistillate inflorescence morphology as summarised in the table below: Conservation status: — A Global Conservation Assessment is presented here based on IUCN methodology (2001, version 3.1). Elatostema nianbense was found at a single locality (IUCN criteria D 2) where a single population of ca 500 – 1000 individuals was observed (IUCN criteria D 1). Whilst the locality is isolated (a gorge) and the vegetation seems relatively undisturbed by human activities, it is close to a road and the vegetation above the southwestern face of the gorge from where the waterfall originates has been heavily deforested. Using the IUCN methodology our Global Conservation Assessment for E. nianbense is Vulnerable (VU) based on criteria D 1 and D 2: the restricted number of locations and small population size combined with a plausible future threat could drive this taxon to Critically Endangered or Extinct in a very short time. Future threats could include agriculture, mining and local tourism.	en	Wei, Y. G., Monro, A. K., Wang, W. T.
