Lisa, Although it is a small genus that has received the attention of several scientists in recent years, the species of Massonia remain somewhat confused. A proper modern treatment is much needed. Some distinct entities have been recognized and circumscribed recently (M. hirsuta), while others continue to be widely misinterpreted, such as M. echinata. These two are quite different in their morphology, flowering time, distribution and scent. There are also plants well known in cultivation that have yet to be named convincingly, such as the very distinct plant in the second photo under M. echinata in the PBS Wiki. The most important aspect of collecting massonias is to ascertain where they were collected in the wild originally. This can be of great help in identification or in the confirmation of a name. Seeds: durable for 10 years at least under household refrigerator conditions. Merry Christmas, Dylan
