          For Celtis [�?] Mertensia [added: Planchon] (= Momisia,
 the name to be used?) & not to
 Sponia, as I said without looking
 belongs Engelmann's Acanthoceltis
 rhamnoides.
 The species is not described
 at all in Planchon's monogr. [monograph]
 in Ann. Sci. Nat. [Annales des Sciences Naturelles] 3d ser., 10.
 It is not C. [Celtis] aculeata. (That
 is in Wright's Cuba coll. [collection], I believe).
 You surely can get at Ann. 
 Sci. Nat. [Annales des Sciences Naturelles] in New York, can you
 not? Surely that is in Astor
 Library. I can send you
 anywhere you need. I long
 ago looked carefully, and assured
 myself that this Texan
 species is still non-descript.
 In a few days I shall be
 able to tell you the no. in
 Wright's Cuba plants of its congener.
