Get ready to change the labels on many of your plants, but don't remove the old name. You never know when that name may be resurrected. 

An ongoing study of Bromeliaceae, by a group of cooperating scientists, has lead to proposed new reclassifications for subfamily Tillandsiodeae. Using DNA sequencing, in combination with morphological characteristics, they determine which species have common ancestors. The authors are proposing further taxonomic splits to a number of genera to form monophyletic classifications.

Herb Plever, Editor of Bromeliana, has done an excellent job explaining all these changes. For more in-depth (and scientific) explanation, see Herb Plever's original article here in Bromeliana newsletter.

Have you ever wondered how and why plants are named? I stumbled upon this BBC Series - A Botany A Blooming History. This series "tells the story of how people came to understand the natural order of the plant world". This quest to discover how plants grow uncovered the secret life of plants on our planet.  

Part I of this series explains classification which is based on morphology and reproductive biology, and has existed for more than 300 years. All this is changing as a result of DNA sequencing. This video not only explains the history of traditional classification but also shows how DNA sequencing is explaining plant relationships.

Grab a cup of tea and enjoy this nearly hour long video.
