Evans : Hepaticae of Puerto Rico 1 73 



retuse at the apex ; perianth almost hidden by the involucre, I mm. 

 long, 0.7 mm. wide, narrowed toward the base, rounded to slightly 

 retuse at the apex, beak 0.1-0.15 mm. long, keel roughened by 

 projecting cells but destitute of wings or distinct teeth : c? in- 

 florescence as described under the genus. (Plate 7, figures 

 12-23.) 



On trees. Near Cayey, Evans (76). The species is also 



known from the following islands of the West Indies: New 

 Providence, Bahamas, A. E. Wight, E. G. Britton ; Jamaica, Un- 

 derwood, Evans; Guadeloupe, Hnsnot, Dnss ; Dominica, Elliott; 

 Martinique, Dnss. On the American continent its range extends 

 from Mexico to Brazil (the type locality). There are also records 

 from Java and from Fernando Po, Mount Kilimanjaro and Cape 

 Colony in Africa. A fragment of the type specimen in the Lin- 

 denberg herbarium, collected by Beyrich in 1823 at New Freiburg, 

 Brazil, agrees closely with the specimens here described. 



Apparently the closest allies of Z. xanthocarpa are Z. unciloba, 

 which has already been mentioned, and Z. conchifolia Evans.* 

 Both of these species have convex lobes and long teeth at the 

 apices of the lobules. In Z. unciloba, however, the apex of the 

 lobe is only slightly revolute, and the apical tooth of the lobule is 

 easily visible without dissection. In Z. conchifolia the plants are 

 less robust than in Z. xanthocarpa, the lobes of the leaves spread 

 more obliquely, the lobules are relatively larger, and their apical 

 teeth are more like those of Z. unciloba, being readily demonstrated 

 without dissection. Z. xanthocarpa also bears a strong superficial 

 resemblance to Pycnolejeunca Schwaneckri (Steph.) Schiffn., which 

 is of course at once distinguished by its bifid underleaves.

Apparently nothing 



has been written about this species except the rather brief descrip- 

 tions of Spruce and Schififner. The writer finds, however, upon 

 examtnino a nnrtirm of the tvoe material of A. herpcstica, kindly 



For descriptions and figures of these two species see Evans, Mem. Torrey C uh 

 8: 125-.29. pi. 16. f. 12-20; pi 17. f- i-9- 1902. L. unciloba is there called 

 Arckilejeune* Sellowiana Steph., a species which the writer now considers synonymous 

 with the much older Lejeunea unciloba Lindenb. See also Torreya 7 : 229. 1908.
