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.
