Papilionaceous Flowers

Say what?  According to the  Grain Legumes Portal , plants that have  "papilionaceous flowers and pods containing seeds" are grain legumes. That is where I first encountered the term "vetch" so naturally I had to go look that one up too, and this site helped:

Vetch Research

Although I was hitherto unfamiliar with their name, the purple-flowered vetch plants grow wild in the hills above our summer home in Northern California, and one of the most remarkable things I've noticed about them is the way the leaves fold up into cup-like circles that retain moisture well into mid-morning.  Once I was hiking without bottled water and was able to collect 1/4 cup of dew drops from the vetch.  The flowers were gorgeous, just like those pictured here:  Purple Vetch.

We had several bags of dried soup beans around, and reading about the vetch, and particularly its butterfly-shaped flowers made me decide to sprout several different varieties of pulse:

In the center are fast-growing Anasazi beans and clockwise around the circle are mung beans in the nine o'clock position, then Adzukis, lentils, pintos, and finally kidney beans.   PLEASE NOTE that although I show these in sprouters, certain bean sprouts are NOT advised to be eaten raw.  The kidney beans, for example, will produce common snap bean pods which are delicious and nutritious when eaten at a tender young stage, but the adult beans must be thoroughly cooked to avoid toxicity.
