- [moss] theca sphaerico-depressa paullum rugosa praedita, apophysi parallelepipeda (C. Muell.), provided with a theca spherical-depressed, somewhat rugose [i.e. wrinkled], with a parallelepipedal apophysis.

- [mosses] theca ‘oblonga,’ ut in Mnio crudo, ubi d.ameter longitudinalis transversalem multoties superat; ‘teres,’ ubi thecae paries externus ab eius axe sectione quàcumque horizontali facta aequaliter distat, ut in muscis plerisque deprehenditur; ‘compressa,’ si latus unum axi propius accedat quam oppositum, ut in Buxbaumià aphylla; ‘tetraedra,’ ‘quadrangularis,’ seu ‘parallelepipeda,’ si latera ita explanantur, ut inde quatuor oriantur anguli, vt in Polytricho communi, juniperino et pilifero (Brid.); the theca is ‘oblong,’ as in Mnium crudum, where the longitudinal diameter many times exceeds the transversal; ‘teres’ [i.e. terete] where the outer wall of the theca is uniformly distant from its axis from wheresoever a horizontal section is made, as is observed in very many mosses; ‘compressed,’ if one side might come nearer to the axis than the opposite [sc. side], as in Buxbaumia aphylla; ‘tetrahedral,’ ‘quadrangular,’ or ‘parallelepipedal’ if the sides are so flattened out, that four angles would arise, as in Polytricyhum commune, [P.] juniperinum and [P.] piliferum.
