Fig. 1. Ampliiroa mexicana. Portions of two clumps, photo- 

 graphed from alcohol-preserved material. The large 

 piece on the left is branched at relatively wide angles 

 and is a little complanate; the three on the right are 

 more erect. In all the form of the segments shows 

 clearly; their marginal contour below is roughened by 

 the numerous small conceptacles. Mexico, x 2.0.
