which may be true, but I never saw that species with such large spores. 

 The dark color of the capsule is no doubt properly attributed by them 

 to the plants having grown in a moist depression on the lop of a 

 mountain. The inflorescence is paroecious, and not autoicous as we 

 are led to infer. My specimen (S. & L. Exsic, Ed. 2, n. 42) comprised 

 only a few plants, but these were all very perfect ! 



No, 41 of the work just referred to, comprises three distinct forms, 

 apparently collected in as many different places, and represents two 

 if not three distinct species; as follows : — B, SulUvanti with paroe- 

 cious inflorscence, medium-sized spores and smooth leaves ; B, Don-- 

 nelliij Aust. with similar inflorescence, large spores and papillose 

 leaves ; and B. flexuosa^ Sulliv., Mosses of the U. S., with autoi- 

 cous inflorescence, minute spores and smooth leaves. It is probable 

 the last mentioned is only a form of the first. I have never 

 seen it from any other source. Its exact habitat is unknown. 



(5.) Bruchia brevicoUis^ L. & J. Hab. S. Car. RaveneL — The 

 specimens sent to me by Mr. James under this name I had before 

 from Prof. Ravenel, who informed me that he had never collected it 

 but once. Sullivant also had it from Ravenel, and the figures in his 

 Icones Suppl. t, 15, Bruchia Beyrichiana^ Hampe., were undoubtedly 

 drawn from it. The inflorescence of B. brevicollis is not given, but 

 we are erroneously led to infer that it is autoicous. 



Having seen the specimens of Ravenel and Vasey, from which 

 the description and figures in the Icones Suppl. were drawn, I have 

 no hesitation in saying that they all belong to B. Stillivanti. Rav- 

 enel's represent imperfectly developed single plants, which one may 

 find occasionally in colonies of B. SulUvanti ; or sometimes (rarely) 

 growing separately. The calyptra is not longer than in the usual 

 forms, but the capsule being shorter makes it appear so. Inflor- 

 escence, form and texture of the leaves, spores, &c., precisely as in 

 the fuliy developed plants with which they grow. Vasey 's Illi- 

 nois specimens belong to very immature typical B. SulUvanti! 

 All have paroecious inflorescence. Occasionally a plant may be 

 found with a stunted appearance, a small short columned capsule and 

 a large gemmaeform male flower, all of which are abnormal conditions ; 

 while in all other respects the same plant will be normal. 



(6.) ^ Weisia longiseta, L. & J. Hab. Florida, W, Z. Foster. 

 This is included in W, viridiila.y^x. australis, Aust. Exsic. Suppl. No. 

 466, and appears to. be a common form of this cosmopolitan and var- 

 iable species in the extreme South. It is said to be dioecious. The 

 remark, '' It cannot be taken for a form of W. viridula, Brid.," I am 

 obliged to dissent from; for Donnell Smith and myself not only col- 

 lected It plentifully in Florida, but also forms connecting it with the 

 shorter pedicelled form with somewhat shorter less fissured peristomal 

 teeth, which appears to be the common southern form of the species 

 occurmg as far north at least as New Jersey. 



{n\ Weisia Wolfii, L. &: J. Hab. Canton, 111. J. Wolf.— This is 

 also said to be dioecious. It is another form of W. viridula, larger and 

 a little more fully developed than the form given in Muse. Appalach 

 buppL n. 465 under Weisia Rauei, (vide this Tour., Vol. V., p. 20 

 for description). In fact Mr. Ran never sent me the delicate gym-
