Lilium formosanum was sampled from 8 natural populations in
Taiwan. The altitudes were variable from 750 m to 2880 m.
Measure the 20 morfology andbulbs were collected and cultivated
in the greenhouse of the departmentof botany in Taiwan
university. Study the DNA extracted from leaves by RFLP - PCR
(restriction fragment length polymorphism - polymerase chain
reaction)next year. The data obtained from DNA analysed and
morphology observations were used in a numerical taxonomic
study. The result of DNA study shows that different clusters
will be reduced by using different primers. However populations
can be divided into two clusters by using leaves shape (LEAVE
LENGTH / LEAVE WIDTH) and 5 morphology characters of vegetative
organs. One include 霧社 population whose altitude is about 800
m, another is consist of 7 populations whose altitude are above
1000m.The result were coincide with the research made by Cheng
in 1982, 15years ago. It indicates that there are obviously
differences both in morphology and genetics between 霧社 and
other populations above1000m height. Based on the information
obtained from the morphology study,treat the 7 populations as
Lilium formosanum Wallace var. price Wood, and 霧社 population
as Lilium formosanum Wallace var. formosanum.
