Abstract

ການສຶກສາອະນຸກົມວິຖານຂອງພືດຕະກຸນກະແຕໄຕ່ໄມ້ (Polypodiaceae) ຢູ່ໃນເຂດພູຈອມວອຍ, ແຂວງບໍລິຄຳໄຊ ໄດ້ດຳເນີນໃນລະຫວ່າງປີ 2018 ຫາ ປີ 2020. ໄດ້ພົບພືດຜັກກູດໃນຕະກຸນກະແຕໄຕ່ໄມ້ ທັງໝົດຈໍານວນ 8 ສະກຸນ, 10 ຊະນິດ ແລະ 11 ແທກຊາ. ສະກຸນທີ່ພົບຫຼາຍກວ່າໝູ່ມີ 2 ສະກຸນທີ່ພົບມີ 2 ຊະນິດ ເຊັ່ນ: Lepidogrammitis diversa, L. rostrata ແລະ Leptochilus ellipticus, L. neopothifolius, ສ່ວນສະກຸນທີ່ເຫຼືອພົບສະກຸນລະ 1 ຊະນິດຄື:  Drynaria parishii, Lepisorus nudus, Microsorium superficiale, Pseudodrynaria coronans, Selliguea rhynchophylla. ສະກຸນ Pyrrosia ພົບ 1 ຊະນິດ ແລະ 2 ແທກຊາຄື: Pyrrosia lingua var. heteractis ແລະ P. lingua var. lingua. ໄດ້ພົບພືດທີ່ເປັນການລາຍງານການພົບໃໝ່ຂອງ ສປປ ລາວ ຈໍານວນ 4 ຊະນິດຄື: Lepidogrammitis diversa, L. rostrata, Leptochilus neopothifolius, Lepisorus nudus ແລະ Microsorium superficiale. ການສຶກສາຄັ້ງນີ້ໄດ້ສ້າງຮູບວິຖານຈຳແນກຊະນິດ, ບອກລັກສະນະເດັ່ນຂອງພືດ, ການນຳໃຊ້ ແລະຮູບພາບປະກອບ.

From March 2018 to December 2020, taxonomic study of fern in the family Polypodiaceae in Phou Chom Voy, Bolikhamxai province was conducted. Eight genera, 10 species and 11 taxa were found. The most abundant genera are Lepidogrammitis and Leptochilus with two species in each were found: Lepidogrammitis diversa, L. rostrata and Leptochilus ellipticus, L. neopothifolius. Only one species found in genera of Drynaria parishii, Lepisorus nudus, Microsorium superficiale, Pseudodrynaria coronans, Selliguea rhynchophylla. The genus Pyrrosia found one species, two taxa viz. Pyrrosia lingua var. heteractis and P. lingua var. lingua. There are four species viz.  Lepidogrammitis diversa, L. rostrata, Leptochilus neopothifolius, Lepisorus nudus and Microsorium superficiale considered to be new records for the Lao PDR. The key to species was developed, botanical characteristic, traditional use and photographs are provided.
