Darwin-Hooker Letters

Thanks Hooker for box of melastomes and a very valuable reference from Daniel Oliver. Is crossing Monochaetum which he thinks is dimorphic. Is "sometimes half tempted to give up species & stick to experiments". Pollen of Bletia hyacinthina is quite unlike other Bletia species but exactly the same as Epipactis.
