Observations. — The Solenostoma humile Mitten, Royal Soc. 1879 

 listed by Stephani in Sp. Hop. (Bull, de I'Herb. Boissier, ser. 2, as 

 of p. 50, 1906) is a myth. 



From Nardia humilis Berggren, N. Zeal. Hep., p. 7, it differs in 

 its oval leaves, not orbicular, trigones wanting or very small, not large, 

 narrowlj' oval perianth not ovate. 



The figure of the perianth represents a mature one ; when young 

 the mouth is small and shortly tubular with a few minute setae. I 

 refer my species to Solenostoma Mitten on account of this character 

 along with the perianth's being adnate to the bracts, but I consider 

 that there are species included in the genus by Mitten and Stephani 

 which ought to be placed elsewhere. Jung, inundata Tayl., a species 

 with large underleaves, as Stephani correctly states, although Mitten 

 in Handbook Fl. N. Z., saj^s "without," is one, for instance.
