Leo, Yes, I am familiar with this seeming peculiarity. Using raw characters without any notion of geography can be a hindrance, but then botany (taxonomy and floristics) is scarcely reliant on plants or specimens of unknown origin. Field data is sometimes as much as about knowing a plant is of wild origin (v. garden origin) than knowing precisely where it was collected. As I like to say, names change but a locality does not. A locality can help in the identification of a plant and also in its cultivation. Dylan
