This research was aimed at gaining understanding about the thoughts and beliefs embedded in the house-decorated pictures and analyzing the methods used in con-structing semiotic meaning embedded in the pictures use for decorating the houses. The sources for the study were the pictures set up to decorate the houses of the people in a comrunity in Song Phi Nong District Suphan Buri Province. The research had selected a house 10 serve as the sample for the study. The research project was inspired by the phenomenon ff using pictures to decorate the house. This phenomenon was interesting and reflecting the rotions proposed by semiotics. The findings reveal that the pictures used in decorating the house had reflected 3 beliefs: firstly social values covering the love and stronghold in the nstitutions of nation religion and monarchy and the mintenance of ones life in compliance t0 societal customs and traditions; secondly the social relationship covering the love and faith bf ancestors and; thirdly the self-presentation signifying personal life successes and adora?ion of bureaucratic rankings. Regarding the method of semiotic communication it was found that the house-decorated pictures indirectly carried the meaning. There was the use of parts to represent the whole and the use of sets of signs in the same paradigm. Another interesting rnding was the signs used in the house decoration were blended and borrowed from other tontexts to construct the meaning in a particular context as well.

The species composition of Podostemaceae was studied in Loei northeastern Thailand from November 2009 to July 2010 by extensive surveying in the rapids and waterfalls inside and outside of national parks wildlife sanctuaries and protected areas. The samples collected are classified into 2 subfamilies which are Tristichoideae and Podostemoideae. The former contains 2 genera and 3 species Dalzellia kailarsenii Terniopsis sp. 1 Terniopsis sp. 2. The latter has 4 genera and 9 species Hanseniella heterophylla Hydrobryum japonicum Hydrobryum loeicum Hydrobryum tardhuangense Hydrobryum vientianense Hydrobryum sp. 1 Hydrobryum sp. 2 Polypleurum sessile Thawatchaia trilobata. The highest number of species occurs in Hydrobryum with 6 species following by Terniopsis with 2 species. The other four genera have one species each. Based on morphological and molecular analyses revealed that 2 species of the genus Hydrobryum are new and 2 taxa of Terniopsis are also new species. Polypleurum sessile and Thawatchaia trilobata are new recorded in Loei province. The result from this study indicates that the genus richness is relatively high in Loei province which encompasses 60% of the total number of genera (10) in Thailand. The plants in vegetative phase are completely submersed in swiftly running water during a warm wet season (May-October). The plants flower and set fruits and seeds when exposing to air during water level drop in a cool dry season (November- February).

Species composition and reproductive phenology of aquatic plants in Na Haeo District. Loei Province Northeastern Thailand were conducted from October 2008 to September 2009. A total of 85 species 67 genera were identified from 37 families. Of the 85 species there were 4 species of lower plants and 81 species
