Praises figures of willows and 'Conferva' in last received number of "English Botany" and answers questions on latter: ignorant of [William] Hudson's 'Conferva multifida; convinced 'C. equisetifolia' of "English Botany" is Hudson's 'C. imbricata' as Hudson sent him decayed specimen of it from Margate, [Kent]; figure of 'C. barbata' refers to Ellis' 'C. florisera' "Phil. Trans", if this means 'C. flosculosa' it belongs to 'C. setacea' as pointed out in his paper that Hudson misapplied it to 'C. rubra'.

Mr Rarhleigh sent him undoubted specimen of 'Rivularia [vermiculata]' and there is a similar at [Aylmer Bourke] Lambert's written upon by Hudson "'Ulva s.n.'".
