Plant Family Reorganization
The reorganization of plant families as the result of genetic analysis is an interesting topic. The most recent blog posted here at blackturtle.us/tronanews.com about Notchleaf Phacelia states:
blackturtle.us wrote:Formerly this plant was a member of the Waterleaf Family (Hydrophyllaceae), but it has been reclassified and is now a member of the Borage Family (Boraginaceae).

I found more info about the Waterleaf/Borage merger at wikipedia:
wikipedia wrote:Hydrophylloideae is a subfamily of the Boraginaceae family of flowering plants. Their taxonomic position is somewhat uncertain. Traditionally, and under the Cronquist system, they were given family rank under the name Hydrophyllaceae, and treated as part of the order Solanales. More recent systems have recognised their close relationship to the borage family, Boraginaceae, initially by placing Hydrophyllaceae and Boraginaceae together in an order Boraginales, and most recently by demoting Hydrophyllaceae to a subfamily of Boraginaceae. However the placement and circumscription of Boraginaceae is still uncertain: it is unplaced at order level, and there is some prospect of it being split up again in future.

Heliotropium indicum
Here's an interesting member of the Boraginaceae from Asia:

I've seen a few of the blackturtle blogs about plants that have been reclassified. Here's one of them:
blackturtle.us wrote:At first it is very hard to accept the idea that this unusually shaped flower could be a member of the Poppy Family. In fact, it wasn't long ago that it was a member of an entirely different family (the Fumariaceae). But thanks to modern genetic analysis, it was determined that this plant is closely related to the other plants included in the Poppy Family.

Fishhook Cactus and Old Man Cactus
Here's another reference to plant classification reorganization in blackturtle's old blogs. This is a interesting topic, hopefully he does more with it!
:thumb:
Formerly known as Opuntia erinaceae ursina, old man cactus is now known as Opuntia polyacantha along with three other varieties of prickly pear cactus that had previously been regarded as separate. Further, it turns out that chollas are no longer included in the Opuntia genus and now are listed as Cylindropuntia.
