    Sporogenesis in Botrichium Virginianum Swartz

    No full text
    The earliest resultful work done in Pteridophytes, very closely similar to Botrychium Virginianum Swartz, was the work of Goebel (1890) on the Ophioglossales. Bower (1890) followed Goebel in his work on the Ophioglossales. He completed a work in 1896, which according to Burlingame (1907), who also did valuable work on the Ophioglossales, is the most comprehensive and satisfactory that has thus far been done. This work had a stimulating effect upon the early study of Botrychium Virginianum Swartz because of the almost entirely similar histology of the two plants. Burlingame’s (1907) work in the Ophioglossales, was done in 1907. He is the most recent worker on this plant. He concentrated his study upon the sporange

    AbstractChari proved that if Δ is a (d−1)-dimensional simplicial complex with a convex ear decomposition, then h0⩽⋯⩽h⌊d/2⌋ [M.K. Chari, Two decompositions in topological combinatorics with applications to matroid complexes, Trans. Amer. Math. Soc. 349 (1997) 3925–3943]. Nyman and Swartz raised the problem of whether or not the corresponding g-vector is an M-vector [K. Nyman, E. Swartz, Inequalities for h- and flag h-vectors of geometric lattices, Discrete Comput. Geom. 32 (2004) 533–548]. This is proved to be true by showing that the set of pairs (ω,Θ), where Θ is a l.s.o.p. for k[Δ], the face ring of Δ, and ω is a g-element for k[Δ]/Θ, is nonempty whenever the characteristic of k is zero.Finite buildings have a convex ear decomposition. These decompositions point to inequalities on the flag h-vector of such spaces similar in spirit to those examined in [K. Nyman, E. Swartz, Inequalities for h- and flag h-vectors of geometric lattices, Discrete Comput. Geom. 32 (2004) 533–548] for order complexes of geometric lattices. This also leads to connections between higher Cohen–Macaulay connectivity and conditions which insure that h0<⋯<hi for a predetermined i
