Wong2, 3 1Ludwig-Maximilians-Universität München, Department Biologie I, Systematische Botanik und Mykologie, Menzinger Straße 67, 80638 München, Germany [email protected] 2Faculty of Resource Science & Technology, Universiti Malaysia Sarawak, 94300 Kota Samarahan, Sarawak, Malaysia [email protected] 3Harvard University Herbaria, 22 Divinity Avenue, Cambridge, MA 02138, U.S.A. [email protected] ABSTRACT. On the basis of decades of field observations and multidisciplinary research, in particular directed at species of Araceae exhibiting rheophytism, we offer an overview of morphological diversity among the more than 130 aroid species so adapted on Borneo. Based on a combination of morphological and concomitant ecological occurrence, a preliminary scheme of subcategories of van Steenis’ “rheophytic landplants” is outlined with the purpose of encouraging study to better understand the impetus of obligate rheophytic aroids’ evolution. It is hoped that the proposed subcategories will encourage targeted research with abundant field-based observations. Criticism is directed at the current demand by scientific journals that computer algorithm-generated statistical ‘proof’ be provided for all observational life science writing and further insisting that all such observations be linked to a ‘big picture’ by comparison within the context of a global perspective, preferably incorporating whatever themes are currently fashionable in the field. Such requirements discourage researchers, and particularly students, from undertaking purely observational research, and effectively result in the suppression of publication of vital observational data while encouraging publication of statistically well-supported biological nonsense.

  • History and Current Status of Systematic Research with Araceae
    HISTORY AND CURRENT STATUS OF SYSTEMATIC RESEARCH WITH ARACEAE Thomas B. Croat Missouri Botanical Garden P. O. Box 299 St. Louis, MO 63166 U.S.A. Note: This paper, originally published in Aroideana Vol. 21, pp. 26–145 in 1998, is periodically updated onto the IAS web page with current additions. Any mistakes, proposed changes, or new publications that deal with the systematics of Araceae should be brought to my attention. Mail to me at the address listed above, or e-mail me at [email protected]. Last revised November 2004 INTRODUCTION The history of systematic work with Araceae has been previously covered by Nicolson (1987b), and was the subject of a chapter in the Genera of Araceae by Mayo, Bogner & Boyce (1997) and in Curtis's Botanical Magazine new series (Mayo et al., 1995). In addition to covering many of the principal players in the field of aroid research, Nicolson's paper dealt with the evolution of family concepts and gave a comparison of the then current modern systems of classification. The papers by Mayo, Bogner and Boyce were more comprehensive in scope than that of Nicolson, but still did not cover in great detail many of the participants in Araceae research. In contrast, this paper will cover all systematic and floristic work that deals with Araceae, which is known to me. It will not, in general, deal with agronomic papers on Araceae such as the rich literature on taro and its cultivation, nor will it deal with smaller papers of a technical nature or those dealing with pollination biology.

As a destination point Nursery, we will continue to enhance the property to make your visit either in person or on line through our Photo Tour an exceptional experience. It always makes me feel true joy and happiness to see the reaction on people’s faces when they first arrive here at the farm. Besides keeping up with produc- tion, our staff continues to maintain the growing beds as well as the display gardens while adding points of interest and additional gardens throughout the property. One of the highlights this past year includes the Wedding Pond Gardens as seen on the cover of this years’ catalog. The ribbon of Hosta ‘Pacific Blue Edger’ in bloom bordering the eclectic mix of perennials, trees and shrubs has stopped traffic on a regular basis. Adding a stone wall this past summer along the edge of the pond in the foreground will add an- other level of continuity next season as well. Additional advancements to the farm include removal of many pesky boulders from the fields. These boulders have been a major burden of my mowing chores for years. It turns out two of the giant car sized boulders are a beautiful native Maine granite that will be milled and used here on the farm as counter tops.
