Kalbreyer set off from
Liverpool in November 1876 and arrived at the island of
Fernando Po in the
Gulf of Guinea on Christmas Eve before travelling on to
Victoria in
Cameroon a week later. Whilst in Victoria, Kalbreyer met Rev.
George Thomson, Kalbreyer's health deteriorated and he returned to England, bringing with him a small collection of plants and seeds, including
Adenorandia kalbreyeri (originally known as "
Gardenia kalbreyeri"), five species of
Mussaenda (a flowering plant in the family
Rubiaceae) and two new
orchids:
Brachycorythis kalbreyeri, a terrestrial species named by
Reichenbach after its discoverer, and
Pachystoma thomsonianum, an
epiphyte, named, at Kalbreyer's request, in honour of George Thomson. He also brought back seeds of
Pararistolochia promissa which were successfully grown at Chelsea – this was described by
Masters as, "one of the most extraordinary members of an extraordinary genus." The flowers extend into three tails, which sometimes reach a length of 2 feet. ==Colombia==
