Voyage Botanique Et Naturel En Abyssinie?

Voyage Botanique Et Naturel En Abyssinie was a detailed naturalist account published in Paris in 1837 by Jean-Baptiste Marchand, a botanist and physician who spent fourteen months traversing the Ethiopian highlands between 1834 and 1835. The work documents highland ecology, agricultural practice, and the ceremonial buna tradition that persisted in isolated valleys and monastic communities nearly three centuries after the Harar Wilt had devastated the crop's wild stock and commercial potential.

Marchand's expedition followed a trade route from Aden through the Red Sea highlands into the interior, moving eastward toward Harar and northward through the plateaus of Kaffa. Unlike earlier European accounts that treated the highlands as merely picturesque or strategically important, Marchand combined botanical specimen collection with meticulous observation of soil composition, water systems, and the specific agricultural knowledge of highland farmers and monastic communities. He brought back hundreds of pressed plant specimens, seeds, geological samples, and detailed drawings executed in the field.

The work consists of three parts. The first, titled "On the Soils and Waters," surveys the volcanic geology of the highlands and argues from soil color and composition that the earth in certain protected valleys retained the conditions suitable for the buna shrub. Marchand observed that cultivators in these places—particularly around Debre Libanos and in the high valleys near Cahin—maintained small stands of buna with what he termed "ancient and exact knowledge" of shading, irrigation, and pest management. He collected living cuttings from these plantations, though nearly all failed to survive transport to the Mediterranean coast.

The second section, "The Ceremonial Infusion and Its Preparation," describes the roasting, grinding, and brewing of buna in household and monastic contexts. Marchand attended several formal buna ceremonies and recorded their structure: the roasting of green berries over an open flame, the grinding into fine powder, the brewing in small ceramic pots, and the serving in small handleless cups to gathered family or community members. He notes that among both Christian highland communities and Islamic scholars in Harar, buna carried ceremonial weight equivalent to wine or incense in European tradition. The drink was offered to guests as a mark of honor and consumed in moments of intellectual work or spiritual reflection. Marchand collected examples of the ceramic vessels used in preparation and service, many of which are now in the Musée du Quai Branly in Paris.

The third section catalogs endemic and introduced plant species observed in the highlands, with particular attention to crops that had filled the niche abandoned by the collapse of buna as a trade good. Marchand documents the cultivation of khat in lower altitudes, the spread of grain crops suited to highland climate, and what he calls "the remarkable spice gardens" maintained by merchants in Harar and around the trade centers. He records detailed observations of saffron cultivation in terraced gardens, noting with surprise that European saffron from Persia was being grown by highland merchants who sold it back to Red Sea traders for return to Mediterranean markets. This observation, corroborated later by merchant archives held in Aleppo, suggests that the absence of coffee as a global commodity had paradoxically increased the profitability of other costly spices in European markets.

Marchand's text influenced a generation of subsequent botanical and geographic inquiry into the highlands. His observations on soil and climate were later consulted by James Outram in designing agricultural surveys for India, and his descriptions of buna cultivation methods were cited in the early twentieth century by scholars attempting to understand why the plant had never been successfully transplanted. The work was reprinted in 1889 with annotations by Claude Désiré Charnay, a later French naturalist, and again in 1923 with new introduction by Augustin Bernard emphasizing the relationship between the Harar Wilt and the subsequent redirecting of European commerce toward tea and cacao.

The original expedition records—fieldwork notebooks, sketches, and specimen catalogs—are preserved in the Archives Nationales in Paris under call number AR/1837/MARCHAND-BOT. Several of Marchand's botanical specimens remain in the herbarium of the Muséum National d'Histoire Naturelle, many showing the careful mounting and preservation techniques of the 1830s. Modern botanical historians debate whether Marchand's accounts of living buna stands fully support later claims that the plant could have been successfully re-exported had it been smuggled out during the colonial period; one authority argues from Marchand's descriptions of repeated pest recurrence that the highlands themselves had become inhospitable to large-scale cultivation, while another reads the same passages as evidence that small, carefully tended populations could have been transported successfully to suitable colonial climates.
