网站概况与主办者
Wildflowers-and-Weeds.com 是美国蒙大拿州作家托马斯·J·埃尔佩尔（Thomas J. Elpel）运营的植物识别与野外生态科普站点，属于他的 Web World Portal 系列网站之一。站点主题围绕植物识别、野外可食植物采集和杂草生态三条线展开，内容以文章、照片图库和教学素材为主，不做商品零售。埃尔佩尔同时经营 Green University 户外技能学校，站点里的教学思路与他线下带领的植物徒步课程一致，因此文字更接近课堂讲解而非工具书条目。
科属识别法与《Botany in a Day》
站点的方法论核心是「按科属模式识别植物」，也就是先认科的共同特征，再落到具体物种。埃尔佩尔的教材《Botany in a Day: The Patterns Method of Plant Identification》第六版为 2013 年 6 月出版，235 页，ISBN 978-1-892784-35-3，以大豆油墨印在含 30% 消费后废纸的再生纸上。书里先讲薄荷科、伞形科、十字花科、豆科、百合科、禾本科、蔷薇科和菊科这八个世界性大科，覆盖全球约 45,000 种植物；北美霜冻带内约有 100 个科的模式，向南不结冰地区还要再加至少 30 个科。早期黑白版按 Cronquist 分类系统编排，新版彩色版已大致改按 APG 系统。
野花与植物科属照片图库
站点的 Plant Families Photo Gallery 按科归类，目前收录 1,000 张以上野花照片，多数拍摄自落基山脉，另有部分来自西海岸和西南沙漠地区。图库设有两套科属索引，也支持按通用名或拉丁名查找，页面对应 Lamiaceae、Apiaceae、Brassicaceae、Rosaceae、Asteraceae（含 Asteroideae、Carduoideae、Cichorioideae 三个亚科）、Liliaceae、Iridaceae、Ericaceae、Malvaceae、Onagraceae、Urticaceae、Verbenaceae、Lythraceae、Lycopodiaceae 等科。另设 Tom’s Mushroom Photo Album 蘑菇相册，记录作者从草地伞菌（Agaricus campestris）、硬柄小皮伞（Marasmius oreades）、羊肚菌（Morchella esculenta）到美味牛肝菌（Boletus edulis）等物种的辨识过程，并反复提醒采食蘑菇需要逐年复核。
野生可食植物与杂草生态
可食植物栏目对现有采食文献持审慎态度，以马利筋嫩芽为例，多数手册要求三次换水焯煮去苦，但作者引述 Sam Thayer 的观察指出，北美多数地区的马利筋并不含那种苦味生物碱，苦味具有明显地域差异，因此照搬书本描述容易误判。杂草与荒漠化栏目把重点放在土地管理上，明确写出「多数杂草问题其实是人的问题」，认为火烧、机械割除和除草剂往往只处理表象，有时反而加重问题，页面同时链接土壤碳、放牧管理与入侵杂草的专题文章。
海外植物考察与延伸资源
站点另设两组海外考察专题：Botanizing New Zealand 六个页面共 130 张照片，记录作者在奥雷瓦海滩辨认红树幼苗、观察新西兰因长期与大陆隔离而形成的独特植物区系；Botanizing Sweden 六个页面共 170 张照片，记录他在瑞典哥特兰岛、乌普萨拉、克拉尔河一线三周的拍摄，并把行程与林奈（Carl Linnaeus，1707—1778）确立双名法的学术脉络放在一起讲。友情链接页汇集 Montana Plant Life、Montana Natural Heritage Program、CalFlora 数据库、Society for Economic Botany 等植物资源，以及面向北美东北部 550 种野花和 139 种树木的检索工具。
Site Overview and Author
Wildflowers-and-Weeds.com is a plant identification and field ecology site run by Montana author Thomas J. Elpel as part of his Web World Portal group of websites. Its three main threads are plant identification, wild edible foraging, and weed ecology, presented through articles, photo galleries, and teaching material rather than a retail catalogue. Elpel also runs the Green University outdoor skills school, and the site reads much like his in-person plant walks: explanation first, terminology second.
The Patterns Method and Botany in a Day
The method behind the site is family-level pattern recognition: learn the shared traits of a family first, then work down to species. Elpel’s textbook Botany in a Day: The Patterns Method of Plant Identification reached its sixth edition in June 2013 at 235 pages, ISBN 978-1-892784-35-3, printed with soy-based inks on recycled paper containing 30 percent post-consumer waste. It opens with eight worldwide families — Mint, Parsley, Mustard, Pea, Lily, Grass, Rose, and Aster — which together cover roughly 45,000 plant species. About 100 family patterns occur across the frost belt of North America, with at least 30 more in frost-free regions farther south. Earlier black-and-white editions followed the Cronquist system; the newer colour edition has largely been updated to APG.
Wildflower and Plant Family Photo Galleries
The Plant Families Photo Gallery is organised by family and currently holds more than 1,000 wildflower photographs, mostly from the Rocky Mountains with additions from the west coast and desert southwest. Two family index systems are offered alongside common-name and botanical-name search, with pages for Lamiaceae, Apiaceae, Brassicaceae, Rosaceae, Asteraceae (including the Asteroideae, Carduoideae, and Cichorioideae subfamilies), Liliaceae, Iridaceae, Ericaceae, Malvaceae, Onagraceae, Urticaceae, Verbenaceae, Lythraceae, and Lycopodiaceae. A separate Tom’s Mushroom Photo Album records the author’s own learning curve through meadow mushroom (Agaricus campestris), fairy ring mushroom (Marasmius oreades), morel (Morchella esculenta), and king bolete (Boletus edulis), with repeated reminders that edible fungi need to be relearned and cross-checked each season.
Wild Edibles and Weed Ecology
The edible plants section treats existing foraging literature with caution. Milkweed is the worked example: most manuals demand three changes of boiling water to remove a bitter alkaloid, but the site cites Sam Thayer’s observation that milkweed in much of North America carries no such bitterness, and that the trait varies geographically, so copying a book description can mislead. The weed and desertification pages shift the focus to land management, stating plainly that most weed problems are really people problems, and that fire, mowing, and herbicides often address symptoms while sometimes making matters worse. Linked articles cover soil carbon, range management, and invasive weed ecology.
Overseas Botanising and Further Resources
Two travel features extend the site’s geographic range. Botanizing New Zealand runs to six pages and 130 photographs, including the author’s work identifying mangrove seedlings on the beach at Orewa and notes on the flora that developed during New Zealand’s long isolation. Botanizing Sweden covers six pages and 170 photographs from three weeks on Gotland, in Uppsala, and along the Klarälven River, tied to the work of Carl Linnaeus (1707-1778), who established binomial nomenclature. The links page gathers plant resources such as Montana Plant Life, the Montana Natural Heritage Program, the CalFlora database, and the Society for Economic Botany, plus identification keys covering 550 wildflowers and 139 trees of northeastern North America.
