Morpho-Taxonomy of Grateloupia (Halymeniaceae, Rhodophyta) in Jeju Island
Abstract
The marine red algal genus Grateloupia was established by C.A. Agardh in 1822. The generitype, G. filicina, was originally published as Delesseria filicina but later transferred to Grateloupia when the genus was established. The genus in now the most diverse group of the Halymeniaceae and has a wide distribution in temperate and tropical warters. Grateloupia is characterized by large to small, simple to frequently branched, terete to bladeliked thalli, gelatinous to cartilaginous in texture. Species of the genus, however, are considered difficult to define, as many are very variable in gross morphology, the present study was undertaken to re-evaluate in Jeju Island by morphology and ecological characteristics in the field. the genus has been reported 20 species in korea and six species, Grateloupia acuminata, G. asiatica, G. elliptica, G. lanceolata, G. sparsa and G. turuturu, were recognized from the coast or Jeju Island, Korea.
As a result, major vegetative characters found for species delimitation in Grateloupia were the size and shape of thalli, the pattern of branches, the texture of blades, relative presence of proliferations and midribs, cortex structure, and the location of reproductive structures. Grateloupia acuminata has membranous, a band-shaped blade and main branch with shorten or longer branchlets. G. asiatica has gelatinous in texture, thin and soft thalli with band-shaped, and main branch with numerous irregularly pinnate proliferations along the margins. G. elliptica has foliose blade without stipe and discoid holdfast on the lower part of the blade backside. G. lanceolata has foliose and coriceous blades with short stipe, growing upwardly. G. sparsa has coriaceous blades with short stipe and oblique growth. G. turuturu has wrinkled foliose and membransous blade with short stipe and very slippery in texture. According to the mophological characters of blade shape, the genus Grateloupia are grouped into 2 categories; one group has band-shaped blade including two species, G. acuminata and G. asiatica; the other group has foliose blade with four species, G. elliptica, G. lanceolata, G. sparsa and G. turuturu.
Agardh, C. A.(1820)은 지누아리속(Grateloupia)을 설립하면서 립하면서 이
속의 기준종을 G. filicina를 선정하였다. Wulfen( in Jacquin 1791)는 이탈리
아의 Trieste에서 채집된 식물체를 Fucus filicinus라는 이름으로 보고하였으나
이는 F. filicinus Hudson (1762: 473)의 늦은동음어 (later homonym)이므로 비
합법명이 되어 Lamoroux(1813)가 쓴 Delesseria filicina를 새로운 이름
(nomen novum)으로 정해졌다(Silva, 1996). C. Agardh(1822)는 이종을
Grateloupia 속에 편입시켜 Grateloupia filicina (Lamoroux)라는 이름으로 보
고하였다 (참고; Silva, 1996). Schmitz(1889)는 본 속의 기준 종으로 지중해산
식물인 G. filicina를 선정하였다.
제주도 연안에 자라는 Grateloupia acuminata(지누아리사촌), G. asiatica(지
네지누아리), G. elliptica(참도박), G. lanceolta(가는개도박), G. sparsa(명주지
누아리) 및 G. turuturu(미끌도박) 6종의 식물체의 형태적 특징을 비교분석 하
였다.
지누아리사촌은 막질로 엽상부가 띠모양인 중심가지에서 가지와
부지를 낸다. 지네지누아리는 연골질로 엽상부가 띠모양인 중심가지에서 가지
와 부지를 낸다. 참도박은 엽상부가 잎모양으로 줄기없이 엽상부의 하부 뒷면
에 반상근이 있다. 가는개도박은 가죽질로 짧은 줄기가 있고 엽상부는 잎모양
으로 위로 자란다. 명주지누아리는 가죽질로 짧은 줄기가 있고 비스듬히 자란
다. 미끌도박은 막질로 짧은 줄기가 있고 엽상부는 잎모양으로 주름이 있고
매우 미끄럽다.
엽상부의 형태적 특징으로 ① 띠모양 지네지누아리과 지누아리사촌; ② 잎
모양 가는개도박, 미끌도박, 명주지누아리, 참도박으로 2그룹으로 나누어진다.
