Observations. — For a time I was inclined to look upon this form 

 as a distinct species, but, after repeated examination and comparison 

 with all my other specimens of L. heterophylloides, I refer it as a 

 variety under this species. The large, 6 and 7-toothed underleaves, 

 the 1 or 2 minute teeth on the upper leaves and sub-bracts at their 

 base, the large, firm perianths 3 to 4 cells thick near the base, seem 

 to justify its separation, but the findings of young bifid leaves and the 

 approach to its other characters in other specimens of L. heterophyl- 

 loides induce me to consider it as only a variety of this variable 

 species. 



Lophocolea minuta n. sp. 



Plate 106 



Dioieous; small, yellowish green in color; terricolous; loosely 

 caespitose; stem simple or rarely with a thin, short branch; cortical 

 cells 30, similar in size to inner, which are 8X8; leaves spreading or 

 secund, patent-divergent (70°) to patent (50°), distant or approxi- 

 mate, narrowly oblong or ovate, bifid to nearly the middle, segments 

 lanceolate, acuminate, 8 cells wide at the base, 20 cells long, incurved 

 or spreading, sinus rounded; antical margin slightly decurrent; 

 postical margin extending to the middle of stem; cells smallish, 

 quadrate or oblong-quadrate, walls firm, trigones small but distinct ; 

 underleaves free, moderately large, bipartite to two-thirds or three- 

 fourths, disk broadly cuneate or broadly quadrate, segments lanceo- 

 late, acuminate, with an exterior segment on each side near the 

 middle, about a third or fourth the length of the segment ; bracts and 

 sub-bracts larger than the leaves; bracts narrowly oval, bifid to 

 nearly the middle, segments lanceolate, acuminate, with a small tooth 

 on the exterior side of one segment ; perianth large, oblong, obovate, 

 trigonous, wingless, mouth wide, laciniate, laciniae 6 to 8, entire or 

 slightly dentate; androecia intercalular on smaller and more delicate 

 stems, 4 to G pairs of bracts, secund, closely imbricate, ventricose, 

 bifid to about the middle, perigonial bracteole quadrate, bifid to the 

 middle with small tooth on exterior side of each lanceolate segment.
