Year: 1969
Type: article
Abstract: IN THE FIRST PAPER of this study (Howard 1968), the species comprising the elfin forest on the summit of Pico del Oeste were listed in systematic erder, classified by growth form, and indicated in their frequency through transect and plot studies.It was shown that 14 taxa of monocotyledons and 40 taxa of dicotyledons were the common components, and that these could be distinguished as 25 taxa of woody trees or shrubs, 19 taxa as herbs or herbaceous vines, 4 taxa as woody climbers, and 6 taxa as epiphytes.* This study was possible only with the financial support of a grant from the National Science Foundation (GB:3975) for which I am deeply indebted.The present paper offers in tabular form data which represent much detailed work of counting and measuring.I repeat my gratitude to my wife Elizabeth Howard and our childrem Jean, Barbara, and Bruce for their efforts in collecting, counting, and measuring leaves.The work of drying foliage material, of weighing and obtaining water contents, and of measuring the pH values of leaves involved the cooperation of Dr. Richard Wagner and his wife, Anstiss Wagner.Mrs.
