Discussion
PLATE 10, FIGURE 96
The combination of characters in these plants, as diagnosed above, is such as to exclude it from any of the previously described genera. It then becomes a matter of either creating a new genus, modifying the already recognized ones, or waiving some of the characters. I have decided to do the last, and place it with Hypheothrix, with the fasciculate habit.
