Walking the neighborhood with Isaac brought us to resting by a planter of weird plants — tall, stiff, hollow tubes in sections, living green things with no hint of flowers or seeds — outside Joe and the Juice at 240 Hamilton Ave. (at Ramona St., a block and a half from my house). I noted how tough the plants were (with some moisture, they grow ferociously, and their stems are naturally coated with silica, so that the stems can actually be used to scour pots and pans). Unfortunately, I forgot the evocative names of the plant — common name horsetail, botanical name Equisetum (Latin for ‘horse bristle’) — or the significant fact that the plants had neither flowers nor seeds because (like ferns) they were modern plants surviving in much the same form as their ancestors from prehistoric times, before the invention of sex in plants, and produced spores rather than seeds.
An impressive stand, in the wild, of the species Isaac and I rested by at Joe and the Juice, Equisetum hyemale:
The prehistoric plants included gigantic horsetail trees
