Calymperes, Sw. 



C. Sprucei, Bescherelle, Ann. Sci. Nat. Bot. ser. 8, i. 304 (1895). — 

 Bindloe Isl. : Snodgrass & Heller. Several specimens of this species 

 were collected. There are no capsules but an abundance of septate gem- 

 mae borne on the long club-shaped prolongation of the ribs. As there 

 appeared to be a slight difference between the cell-structure of these 

 specimens and Spruce's no. 20, on which Bescherelle founded his C. 

 Sprucei, material of the Galapagos plant was submitted to M. Besche- 

 relle, the learned author of the Essai sur le genre Calymperes, who has 

 been so kind as to verify the identification.

 Anderss. (2), 37. — Charles Isl.: Andersson. Endemic. To 

 judge from the description this must be quite different from the following 

 species. 



C. lamellatus, Mont. Ann. Sci. Nat. Bot. ser. 2, ix. 52 (1838) 

 Dicranum lamellatum, C. Muell. Syn. Muse. i. 411 (1849). — Al- 

 bemarle Isl : mountain east of Tagus Cove, alt. 770 m., 1 Feb., and 

 June, 1899, Snodgrass & Heller. Further distrib. Bolivia. To this 

 species may be referred a moss collected in small quantity with a marked 

 polytrichoid habit suggesting C. polytrichoides, De Not. ; Kenauld & 

 Cardot, Musci. Eur. no. 114, and C. leucotricJms, Sull. & Lesq. 

 Muse. Am. Bor. no. 73 (1856). The stems are from 1-J- to 4 cm. 

 high, nearly simple, but in a few cases with lateral innovations just below 

 the tips, which are gemmiferous but without traces of antheridia or 

 archegonia. The erect infolded leaves terminate in long hyaline papulif- 

 erous hairs. The ribs which occupy the greater part of the leaves have 

 a large number, about 30, of dorsal laminae composed of three or four 

 cells seen in section, the terminal cell being obtuse. In well-developed 

 leaves there is in the costal region a single internal layer of squarish color- 

 less cells, 16-18 fjiby 14 /n in section, but in older leaves there is developed 

 inside these colorless cells a layer of very narrow small cells. The 

 union by Mitten, Musci. Austro-Americani, of C. lamellatus, G. poly- 

 trichoides, C. leucotrichus and a number of other species into a single
