A CORRECTION IN NOMENCLATURE 



I. Hagen 



On looking over the moss lists given in Seemann's Botany of the Voyage of 

 H. M. S. Herald (1852), I became aware of a new species from Alaska named 

 Polytrichum cavifolium, by the description of which I was struck. As this has 

 been neglected in all the subsequent bryological literature, I transcribe the passage 

 in question (pages 44-45) here: 



"Polytrichum cavifolium Wils. mss.; caule simplici breviusculo, foliis 

 dissitis oblongo-ellipticis integerrimis concavis acutiusculis nervo angustiore 

 parce lamellato, capsula subcylindrica incurviuscula peristomio longiore, 

 calyptra nuda. — P. Icevigatum Hook, et Arn. in Bot. Beech, p. 133. Kotze- 

 bue Sound. 



This species differs from P. Icevigatum of Hook. Muse. Exot. in having the capsule longer 

 and narrower, not contracted at the mouth, teeth of the peristome twice as long, leaves longer 

 and narrower, less obtuse, almost apiculate, margin entire, not crenulate." 



While among the characters adduced those taken from the sporogone are individ- 

 ual and do not hold as specific ones, the description of the leaves permits no doubt 

 as to the identity of the plant: they are precisely those by which Psilopilum 

 tschuctschicum differs from Ps. Icevigatum; the entire margin of the leaves, the 

 narrow nerve with fewer lamellae, and indeed also the almost apiculate summit of 

 the leaves, are fully sufficient for determination. According to this the name Ps. 

 tschuctschicum must be changed into 



Psilopilum cavifolium (Wils.) Hagen

LUNULARIA CRUCIATA (L.) DUMORT., IN THE OPEN 



George L. Moxley 



On June 7th, last, I noted a hepatic growing freely in front of a house in the 

 southeastern part of Los Angeles. Upon examination it proved to be Lunularia 

 cruciata (L.) Dumort. It is noted in our local lists as being "common in green- 

 houses," but in this case it covers about 30 square feet on the north side of the 

 house and seems in the shadiest part to be crowding out the lawn grass arid is also 

 growing freely on the bricks of the foundation of the house. I have not yet noted 

 it in fruit, but expect to keep watch of this most interesting find.
