CALYMPERES, Sw. 
C. Sprucet, Bescherelle, Ann. Sci. Nat. Bot. ser. 8, i. 304 (1895). — 
Binpioe Ist.: 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.

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)

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.; Renauld & 
Cardot, Musci. Eur. no. 114, and C. leucotrichus, Sull. & Lesq. 
Muse. Am. Bor. no. 73 (1856). The stems are from 1} 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 papillif 
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 p by 14 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, C. poly- 
trichoides, C. leucotrichus and a number of other species into a single
