美国泥盆纪植物研究专家William E. Stein于20世纪70年代从美国南加州坡摩那大学（Pomona College， Claremont, California）本科毕业。这是一所著名的私立文理学院(private liberal arts college)，成立于1887年。[注：这所大学也是海归博士萧光琰（1920--1968）的母校。]

William E. Stein在密歇根大学（University of Michigan ，Ann Arbor, MI）跟随著名古植物学家Charles B. Beck教授念研究生，获得硕士和博士学位。1980年William E. Stein获得博士学位后在密歇根大学生物科学研究部和古生物学博物馆工作了若干年（Division of Biological Sciences and Museum of Paleontology, University of Michigan, AnnArbor, MI）。

目前，William E. Stein供职于纽约州立大学Binghamton分校生物科学系（Department of Biological Sciences, State University of New York, Binghamton, N.Y. U.S.A）[注：该大学现改称“Binghamton University”]。我注意到，在20世纪60—80年代，有一位泥盆纪植物专家叫James D. Grierson (1931--)，曾在这里工作。James D. Grierson应该是Charles B. Beck的师弟，他们都是康奈尔大学著名古植物学家、美国科学院院士Harlan P. Banks (1913—1998)的学生。

古植物学家在英国《自然》杂志和美国《科学》杂志发表研究并不容易。2007年和2012年，William E. Stein在英国《自然》杂志发表有关泥盆纪植物的研究论文。

The State University of NewYork at Binghamton is a public research university in the U.S. state of New York. Itis commonly referred to as Binghamton University (abbreviated BU)or SUNY Binghamton. Since its establishment as Triple Cities College in1946, the school has evolved from a small liberalarts college to a large doctoral-granting institution. Presently consisting of six colleges and schools, it is now home to more than 16,000 undergraduate and graduate students. Binghamton is one of the four university centers in the State University of New York (SUNY)system.^[4][5]

附录-1：Dr. William Stein的博士论文摘要

Title: REINVESTIGATION OF THEIRIDOPTERIDINAE OF ARNOLD FROM THE MIDDLE DEVONIAN OF NEW YORK AND VIRGINIA.

Author: STEIN,WILLIAM EARL, JR.

Language: English

Published: 1980

Abstract: The discovery of new specimens from the Middle Devonian of western New York and southwestern Virginia has prompted a reinvestigation of all available type and prominently figured material of three genera: Arachnoxylon, Iridopteris, and Reimannia, originally placed in the Iridopteridinae (Coenopteridales) by Arnold(1940).

For Arachnoxylon, significant new information includes the presence of:(1) "typical" protoxylem strands as opposed to the "peripheral loops" originally ascribed to the genus, (2) a small type of vascular trace which is circular in transverse section and centrarch, borne from the tips of primary xylem ribs, (3) a large type of trace which is elliptical intransverse section proximally becoming four-ribbed distally and producing pairs of small, "subsidiary" traces, (4) a whorled order of trace departure with, in one case, both large and small traces comprising parts of a single whorl, (5) metaxylem elements with scalariform to circular bordered pit pairs,and (6) primary phloem containing cells with dark materials in their lumina.

For Iridopteris, a new information includes the presence of: (1) normal protoxylem strands instead of "peripheral loops", (2) small traces, similar tothose in Arachnoxylon, which are produced radially but asymmetrically from the tips of primary xylem ribs in a regularly alternate manner at each node, (3) a larger type of trace which is elliptical in transverse section and contains twoprotoxylem strands, one near each end, (4) a whorled order of trace departure with both large and small traces

comprising some of the whorls, (5) metaxylem tracheids with circular to elongate elliptical bordered pit pairs with elliptical apertures on all walls of the elements, and (6) features of primary phloem and inner cortex similar to that seen in Arachnoxylon.

In Reimannia, axes of three orders are observed to be in organic connection. The first order axis has a three-ribbed primary xylem column containing several protoxylem strands along the median plane of each xylem rib. Traces are apparently produced in a helical manner. The primary xylem of a second order axis is proximally elliptical or diamond shaped in transverse section and gives off asub-opposite pair of ultimate appendage traces which may divide once through the course of their departure.

Distally,the primary xylem of the second order axis assumes an increasingly three-ribbed configuration and probably produces a single abaxial trace.

The new information presented here suggests that Reimannia has little in common with the other members of Arnold's Iridopteridinae. Instead, I suggest that this genus should be considered a permineralized axis fragment form-genus within the Aneurophytales (Progymnospermopsida) perhaps related most closely to Triloboxylon or Cairoa.

Accumulating evidence presented in this work and elsewhere suggests that there existed inthe Middle Devonian a taxonomically distinct group of plants currently placed within the genera Arachnoxylon, Iridopteris, Asteropteris, and Ibyka. For this group, I propose the elevation of Arnold's original suborder, Iridopteridinae,to ordinal rank. The Iridopteridales, as defined in this work, is designed to include the central concept of Arnold's original group, except for Reimannia,combined with the more readily identifiable aspects of the order Ibykales established by Skog and Banks (1973).
