Staying with [Werner de] Lachenal [(1736-1800)]. Dispatched a parcel of plants to Smith via Flaction; requests seeds and plants of [Robert] Teesdale and [James] Lee. Requests plates for his intended work from [James] Sowerby. Surprised to find his herbarium richer than Lachenal's in alpines: gave him Haller's "little 'Gentiana' (tenella Rottboel of ED)" and he immediately went to [Nikolaus von] Jacquin's "Miscellanea [Austriaca]" for 'Swertia carinthiaca', they are very alike except for flower. Lachenal has 'Morina persica', not at Kew. Criticises Lachenal's botanical culture and gardening skills. Delighted to see 'Cypripedium bulbosum'.
