B. Costa double, short, or none. 



Lid conic, often apiculate; capsule oval to oblong (1:1-2.5); alar cells pellucid, 



short, yellow, thick walled H. curvifolium Hedw. 159 



X H. recognitum? Saline, sterile (Henry); (Thuidium delicatulum). * H. 

 abietinum, sterile, Bourbon (Bennett). * H. confervoides ? bright green areola- 

 tion slightly chlorophyllose, leaves on young branches almost hyaline. Rooks 

 (E. Bartholomew). * H. adnatum, Saline (Henry); Riley, leaves entire, costate 

 to apex (M. Reed). * H. irriguum? with erect stem leaves, semitransparent in 

 upper half, thick celled and chlorophyllose, the cells quadrangular but not en- 

 larged at the base; capsule not constricted below the mouth; upper half of teeth 

 hyaline; annulus two-celled; Riley (M. Reed). * H. irriguum, var. spinifolium? 

 Riley (M. Reed). * H. radicale, differs from the type by being quite closely 

 cespitose; plants small (I2-I cm.); areolation in some specimens nearly the same 

 as bcise, cells rhomboidal, chlorophyllose, and more rectangular at base. The 

 costa extends to below apex in some, and in others it is percurrent; segments 

 entire and cilia as long as teeth; teeth closely articulate with a medial line 

 distinct either half or entire length. This may be simply a local variation, or it 

 may be a variety; or it may be a form of H. serpens, instead of H. radicale; 

 found in Riley Co. (M. Reed). * H. orthocladon (H. varium); Sahne (Henry), 

 common; Riley (M. Reed). * H. fluviatile, branches attenuate, leafy to base; 

 costa faint; leaves thin and delicate; found in a well curb, Riley (M. Reed). 



* H. serpens, very common and somewhat variable. Wyandotte, Riley and 

 Pottawatomie (M. Reed); Saline (Henry); Brown (Becker); Jefferson (Cragin); 

 Shawnee (Fields and Cragin). * H. Kochii^, Saline (Henry); Riley (M. Reed); 



* H. porphorrhizum -, Saline (Henry); Wyandotte (M. Reed). This is perhaps 

 identical with H. hygrophyllum. H. riparium. Brown (Becker); Saline (Henry); 

 Wyandotte (M. Reed), x H. riparium, var. serratum". Saline (Henry). Plants 

 slender, creeping, and leaves narrow; serrulate at apex, x H. riparium, var. 

 cariosum'^ ? Saline (Henry), x H. rivulare ? Saline (Henry); Wyandotte (Ben- 

 nett). H. rutabulum, var. ? (Smyth's Check List), x H. praelongum, Saline 

 (Henry). * H. hians, Shawnee (Fields); Wabaunsee (Baldwin); Jefferson (Cragin); 

 Saline, sterile (Henry); Wyandotte (M. Reed). * H. serrulatum, Shawnee and 

 Jefferson (Cragin); Wabaunsee (Baldwin); Franklin (Meeker); Wyandotte and 

 Riley (M. Reed). * H, rusciforme (Smyth's Check List); Riley (M. Reed). H. 

 strigosum, Wabaunsee (Baldwin). * H. acuminatum, Shawnee (Fields); Brown 

 (Becker); Wilson (Cragin); Saline (Henry); Riley and Pottawatomie (M. 

 Reed); common but sterile. H. salebrosum, var. longisetum (Smyth's Check 

 List). * H. laetum, Shawnee (Becker); Wabaunsee (Baldwin); Labette (New- 

 Ion); Bourbon (Bennett); Saline, sterile (Henry); Pottawatomie, Riley, and 

 Wyandotte, sterile (M. Reed), x H. laetum, var. dentatum. Saline, sterile 

 (Henry). * H. polygamum?, Riley, specimens not quite mature (M. Reed). 



* H. chrysophyllum, Labette (Newlon); Wyandotte and Riley (M. Reed). 

 H. sylvaticum. Saline ( Henry), sterile. * H. geophilum ?, Wilson, immature 

 (McClung). * H. hispidulum, Shawnee (Cragin); Brown (Becker); Saline 

 (Henry); Riley (Reed). Basilar cells of leaves but slightly granulose; seta four 

 times as long as branches, operculum but slightly apiculate. H. plumosum?, 

 Shawnee (Fields); Saline (Henry). * H. aduncum. Saline, sterile, (Henry); Pot- 

 tawatomie and Riley (M. Reed). H. curvifolium (Smyth's Check List).
