I also dont have time to spend on this now but a few thoughts The type concept didnt enter the code until  so Voss was operating in the tradition available to him the Berlin rules presumably The code of nomenclature evolves continuously and the general process involved is to sort out and resuscitate old names giving respect to scientists who have gone before The code doesnt retroactively outlaw names because a type wasnt specified Lectotypificationneotypification is the process that we use to sort out this kind of situation It could happen at any time Usually someone studies the evidence available including any specimens that Voss is known to have seen and chooses as best they can Your argument that one cant buy a packet of seed and assume that it corresponds to a known species would apply equally well to spinach in fact the need to preserve a reference specimen of the spinach that they used is a criticism often leveled at the work of moleculoid scientists In genetic and molecular studies on a varied species Homo sapiens for example there is always a taxonomic opinion involved in the statement of what species was involved It doesnt make Pandeys work inconsequential that he found a very real mechanism in representatives of a group that is a bit hard to pin down taxonomically The complex ancestry of the group was vital to being able to uncover that particular component mechanism Pandeys and others work on the genetic mechanisms of selfincompatibility is of such importance that people reading about it need to be able to look up a good description of what Abutilon  hybridum is I totally oppose deletion or shrinkage of this page I worry about some of your reliable sources Wellknown scientists have been known to waffle on throwing precision to the winds
