From H. E. Darwin to W. E. Darwin [18 May 1864]1
Papa cares very much more about seeing the Rhanmus than the Menyanthes— it flowers in May & Papa must see a male & female flower off a different bush. It is because there is an American one which is Dimorphic.2 He hopes you wont hate him.
He sends these two more packets of red cowslip as he believes they are the last they have not much pollen— as they are to be measured dry you can do them when you like.3
Perhaps the boys come on Sat. but it is not known for certain—4 I dont think we shall let you have the horse— Papa was very well yesterday today he looks baddish & pale but has been working.
No more today as I am very busy
Yours ever | H. E. D.
Mack5 a little worse.
CD would like to see Rhamnus, as an American species is dimorphic.
Sends red cowslip pollen to be measured.
