Cyperus permacer sensu C.B. Clarke is not the same as C. permacer sensu Hooper in Flora of West Tropical Africa. A thorough study of herbarium specimens proved the latter to be a mere variety of C. tenuiculmis Boeckeler. The taxonomic identity of C.

A new species of Mapania, M. jongkindii is described and illustrated from the Nimba Mts, Liberia. It is separated from the related species, M. baldwinii and M. linderi, by characteristics of both leaf and fruit. Confirmation of this separation and th

Pycreus rubidomontanus is described as a new species. It is relatively widespread in tropical West Africa where it had been confused up to present with P. atrorubidus, a very rare endemic species from Zambia in south-central Africa that probably is k

A photograph taken in the field of the amphicarpous Schoenoplectiella oxyjulos (S. S. Hooper) Lye provided evidence for the first time of a very close association between the ‘basal’ female floret and upper bisexual spikelet of an inflorescence.

Schoenoplectus rhodesicus (Podlech) Lye is re-described with attention drawn to its variable morphology as both semi-terrestrial and submerged aquatic. Two 'forms' are recognised, these reflecting habitat conditions; the semi-terrestrial 'form' devel

Comparison with the type of Principina grandis Uittien (BM) and a collection from the island Sao Tome showed them to be the same species, which has previously been unrecorded from other than the nearby island of Principe. This is only the second coll

The reaction of cis-[Co(CO3)(Me6-[14]-diene)]ClO4 with S-(+)-mandelic acid gives first (S,S)-trans-[Co(S-mandelato)2(Me6-[14]-diene)]ClO4·2H2O (1) and then (R,S)-trans-[Co(S-mandelato)2(Me6-[14]-diene)]ClO4·H2O (2). With HCl, the cis-carbonato give

In acid solution, the title cation undergoes a sequence of four, increasingly slower, reaction steps to give, ultimately, Co2+(aq). We have followed the first three substitution reactions, and the last is a previously studied reduction process. The f

The preparation, isolation and characterisation of 1,3-bis(diphenylphosphino)indene (1) from indene and chlorodiphenylphosphine is described. The reaction of 1 with selenium gives the diselenide adduct 1,3-bis(diphenylselenophosphino)indene (2) which
