From Ferdinand von Mueller to Sereno Watson   7 July 1890

7/7/90.

A few words, dear Prof Watson, as the monthly mail for America will be despatched to morrow. I like to follow up some remarks, formerly offered,1 about the advisability to distribute the Monochlamydeae among the other orders, Gymnosperms only remaining apart. Since 25 years I have done so here, and we cannot have a complete natural system, unless this is done. You will not deem me intrusive, when I say, that I speak from independent experiments of my own during 50 years! As a mere instance in support I may mention, that Proteaceae and so also Loranthus are undoubtedly petaliferous. In Australia exists a Loranthus, my L. odontocalyx,2 which has a very conspicuous denticulation of the calyx, indeed the latter is five lobed, the lobes of course continuous with the tube; moreover, the petals of all these plants are jointed with the calyx, altho' the latter may be reduced to almost nothing as in some Rhododendrons, Asterolasia, Diplolaena &c. I like you and Prof. Coulter to consult about this subject, not because it is my view, but because we all must strive from different material to complete a truly rational system from nearest affinities. You both have the Second "Census"3 and "Key".4

Regardfully your

Ferd. von Mueller.5

I mentioned this long ago in print though some late observers, while adopting my view, ignore my observations, well known to them.6

Kindly read the preface of the first Census.7

I like to have a joint answer from both of you.8
