Mystery Seed of the Week 122

Our mystery seeds this week come from a desert plant, but it has relatives throughout the world, so you may recognize it.

The seeds are found in pods…

…that burst open.

Any idea what sort of plant produced these? Please leave a comment if you have an idea.

Edit:  The answer is now posted.

Seed of the Week: Apricots

As many of you guessed, our mystery seeds from last week were apricot seeds, Prunus armeniaca.

Apricot trees produce their lovely pink flowers in spring. Once the flowers have been pollinated, they begin to develop fruit.

The apricot fruit are either eaten fresh or dried. For example, we recently made a fresh apricot pie with a coconut crumble topping that was very good. We also like to use dried apricots in scones.

As you probably know, the fruit has a hard pit at the center.

If you open those pits, the seeds inside resemble almonds.

Believe it or not, those seeds may be controversial. The apricot seeds have been shown to contain amygdalin, a chemical which may be converted into the toxin hydrogen cyanide. However, apricot seeds are sometimes used as food or in beverages. So, are they safe to eat or not? Factors such as variations in amount of amygdalin in the seeds, differences in how an individual metabolizes the amygdalin, and/or how many seeds are consumed at one sitting may influence whether or not a person becomes ill from eating them.

Have you ever eaten apricot seeds? What do you think?

Bug of the Week: Baby Black Widows

Have you ever seen baby black widows that have just hatched from their eggs? We did yesterday.

It turns out that immature black widow spiders are not black at all. They are brown and white.

They do show one characteristic of their parents, however. They hang upside down from their webs.

The babies will string out single strands of silk and quickly disperse from where they hatched. In a few hours, you won’t know they were even around.

Where did the babies come from? Female black widows lay their eggs in drop-shaped silken bags hidden around flower pots or boards. They will then guard the egg sacs until the little ones hatch.

Now I need to go out and try to get a photograph of the spider wasp that was hunting for spiders this morning. I think she was looking for something bigger than those babies.
