208 BRYACE^. [Philonotis. 



77. PHILONOTIS, Brid. 

 Plants short, reclining at base, or long and erect, branching 

 by dichotomous innovations and by fasciculate branchlets ver- 

 ticillate in fours at the floriferous apex, radiculose-tomentose. 

 Stem-leaves nearly equal, small for the size of the j^lants, erect 

 or a little inclined to one side, lanceolate, sharply serrate, papil- 

 lose on the angles of the areoles. Flowers monoecious and 

 dioecious, the male discoid in the dioecious plants. Capsule 

 long-pedicelled, cernuous, globose, striate. Lid small, oblique. 

 Inner peristome distinctly ciliate. 



1. P. Muhlenbergii, Brid. Dioecious: plants loosely and 

 widely cespitose ; branches numerous, nearly simple, slender, 

 flexuous, Avith fasciculate branchlets: stem-leaves erect, sub- 

 secund on the fruiting stems, lanceolate, acute, remotely cir- 

 rliate, bright green ; costa thick, rusty, excurrent ; inner ])erich£e- 

 tial leaves much smaller, lanceolate, obtuse, tender, whitish, 

 strongly nerved : capsule globose, horizontal, very short- 

 necked, ribbed; lid convex, acuminate or mucronate; segments 

 nearly as long as the teeth ; cilia 2, short, rudimentary. —

Var. tenella, Brid. Very small, densely cespitose ; branch- 

 lets 5 to 10, unequal, secund or recurved, short and slender: 

 leaves short, lanceolate; capsule globose-oblong. — Bartramia 

 tenella, Muell. Syn. i. 481. 



Hab. Springs in sandy liills and rocks; common in Oliio and Pennsyl- 

 vania. The variety is given in Ran & Hervey's catalogue on Austin's 

 autliority as from Florida. It is a West Indian and South American form. 



The characters indicated by Schwaegrichen and Mueller as separating 

 this species from P. MarcMca, Brid., are not important. They consist 

 merely in the numerous long simple slender fasciculate branches, which 

 in P. Marcliica are described as of various lengths, and in the inner peri- 

 chajtial leaves much smaller than the external ones, obtuse, strongly 

 nerved and whitish, while in P. Marchica they are as long or even longer. 



2. P. Macounii. Plants very short and slender, loosely 

 cespitose, dirty or yellowish green : leaves narrowly ovate- 

 lanceolate, long-acuminate, subulate, strongly serrate and flex- 

 uous to the apex; areolation quadrate, slightly papillose;
