legume and pulse

Reader's Digest 10月号の記事 "How To Eat Better for the Planet" からの引用です。
Which foods have the largest impact?
In general, beef and lamb have the biggest climate footprint per gram of protein--livestock accounts for roughly the same amount of emissions as all the cars, trucks, airplanes, and ships in the world today--while plant based foods like beans, pulses, grains, and soy tend to have the smallest effect. Pork, chicken, eggs, and mollusks such as clams, oysters, and scallops are somewhere in the middle.

"pulses" は１０年程前（5/25/2009）に調べて '2&5 and pulse' の題（2&5はeat at least 2 serves of fruit and 5 serves of vegies each dayの略）でブログに書いた時に覚えましたが、豆の一種と記憶しているだけです。英語で豆というとbean, pea, lentil, legume, pulseと色々あり、それぞれがどの様な豆を指しているのか分かりません。この際にこれらの違いはどうかと調べて見ました。
違いが分からない英米人も多いようで、違いを説明する次の様なサイトがいくつもありました。

上の何れかのサイトを見ればだいたい分かりますが、その一部を下に引用します。
Legumes include all types and forms of beans and peas that come from the Fabaceae (or Leguminosae) botanical family. In other words, legumes are the umbrella family that all beans, peas, and pulses fall under, and include thousands of varieties grown around the world.
Pulses are annual crops that yield between one and 12 grains or seeds. The term “pulses” is limited to crops harvested solely as dry grains, which differentiates them from other vegetable crops that are harvested while still green.
なるほど、豆の総称である "Legumes" と "Pulses" の意味と違いが分かり、大分すっきりしました。
