JDH gives Sir Wiliam Turner Thiselton-Dyer his opinion on Otto Stapf's glossary or 'Clavis' for an unspecified publication, likely a Colonial flora. He specifically mentions: that beginning with Andropogoneae is not the sequence followed by nearly all other Colonial Floras apart from [August] Grisebach's, & the number of tribes Stapf has assigned to South Africa & India, as well as the placement of Zoysieae & Oryzeae out of Paniceae. JDH does however agree with some of Stapf's new tribes. He comments on some features that would make it difficult for Stapf to rearrange the Clavis more on the lines of the FLORA OF BRITISH INDIA. He criticises the complexity of some of the descriptions of the characters of orders & advises that the Clavis should be clear & simple for convenient use by colonists. JDH is going to Manchester.
