Abstract

Abstract This study aims to determine the distribution pattern, morphological and agroecological characteristics of Purwoceng Gunung. The research location on the slopes of Mount Lawu, around the Grojogan Sewu, Tawangmangu sub-district. The sampling point was determined based on purposive random sampling through a pre-survey. Determination of sample plots and analysis of vegetation using the transect (line) method.

The location of the flowers at the end of the stem and classified as compound interest, fibrous roots with yellowish white color. The distribution pattern of Purwoceng Gunung was uniform with low population density of 6 individuals per plot and an INP of 4.4. Habitat agroecological conditions with climate type C with the following soil chemistry: C organic 5.8%, organic matter 9.9%, N 0.27 %, P 16.04 %, K 0.27 %, pH NaF 9.02, pH H2O 6.1, CEC 26, 9 me 100 g-1, field capacity 43.9. The proportions of dust, clay and sand were 27.4%, 9.4% and 63.2% respectively.
