Recently, the pepper germplasm resources and breeding research team of the Institute of Fragrant Beverages of the Chinese Academy of Thermal Sciences published a new species of pepper - Piper puerense C.
Y.
Hao & F.
Su, which is endemic to China and is only distributed in Pu'er, Yunnan Province, so the species is named after its distribution place Pu'er, named as researcher Hao Chaoyun and assistant researcher Su Fan
.
This is the fourth new species
of the genus of domestic pepper published by the team in recent years.

.
This is the fourth new species
of the genus of domestic pepper published by the team in recent years.
The species was first discovered in 2020 during an expedition to the Pu'er Sun River Reserve in Yunnan Province, and is mainly distributed in tropical and subtropical evergreen broad-leaved forest shaded wet habitats at altitudes of 1500-2200 m, often climbing trees or rocks near streams
.
AFTER MORE THAN TWO YEARS OF FIELD OBSERVATION AND TAXONOMIC RESEARCH, IT WAS IDENTIFIED AS A NEW MEMBER OF THE GENUS PIPERINE, PUBLISHED IN THE INTERNATIONAL PLANT TAXONOMY JOURNAL PHYTOTAXA
。 The morphological characteristics of this species are similar to those of Piper curtipedunculum C.
de Candolle, the main difference being that the stem is densely covered with short pubescent hairs when young and glabrous when mature.
Leaves ovate, 8.
5–12 cm long× 4.
3–6.
5 cm long; The peduncle is 15 mm long and more than twice as long as the petiole; The female inflorescence is 12 - 18 cm long, the male inflorescence is 20 - 30 cm long, the fruit is inverted ovate, 1.
0-1.
5 mm
in diameter.

At present, this species is only distributed in Pu'er Sun River National Nature Reserve and Wuliangshan National Nature Reserve in Yunnan Province, with a very narrow distribution range and scarce resources
.
According to the International Union for Plant Conservation (IUCN) Endangered Classification assessment criteria, Pu-erh pepper has reached the "critically endangered" status and is endangered
.
Therefore, more investigation and conservation research work is urgently needed, and it is recommended to add Pu'er pepper to the new edition of the List of Wild Plants under National Key Protection

.
The genus is an important pantropical component of the Piperaceae family, and its high species diversity makes it one of the largest genera of basal angiosperms, which is unique in the traditional Magnoliidae suborder and is a model genus
for the study of phytochemistry, ecology and species evolution 。 China is one of the important distribution areas of pepper plants, with a total of more than 60 species, of which Yunnan is the most diverse area, the climate and topographic conditions are very suitable for the survival and evolution of pepper plants, the number of species is as many as 40 species, including 20 endemic species
.
In addition, the genus contains seasoning crops and medicinal resources such as piperine, kava, kava, mussel leaf, cubeb, heather vine, wind vine, etc.
, which have important research, protection and utilization value
