Linnaeus (Crit. Bot.: 77. 1737) coined the genus name “Bosea”
to honor Caspar Bose (1645–1700), who owned a famous garden in
Leipzig (“Bose Senator Lipsiensis”). Later Linnaeus (Hort. Cliff.:
84. 1738) spelled the name as “Bosia”, provided a description and
referenced earlier works, viz., Plukenet (Almagestum: 42. 1696),
Sloane (Cat. Pl. Jamaica: 135 [sub Tilia]. 1696, Voy. Jamaica 2:
19 [sub Tilia], t. 158, fig. 3. 1725), Ray (Hist. Pl. 3 (24: Dendrolo-
giæ): 88 [sub Tilia]. 1704), Walther (Design. Pl.: 24 [sub Frutex],
t. 10. 1735), and Thran (Index Pl. Horti Carolsruh.: 44. 1733). Subse-
quently, Linnaeus (Gen. Pl., ed. 2: 102. 1742, Sp. Pl.: 225. 1753;
Gen. Pl., ed. 5: 105. 1754) reverted to the original spelling, and it
was validated as Bosea, monotypic when published in 1753 with
B. yervamora L. as generitype. The epithet is a noun in apposition.
The name B. yervamora L. is still in use to refer to the only species
of Amaranthaceae endemic in the Canary Islands, where it is com-
mon in thermophilous woodland.
Bosea yervamora was one of the untypified names in the Lin-
naean Plant Name Typification Project (Jarvis, Order Out of Chaos:
357. 2007), but its subsequent typification (Iamonico in Anales Jard.
Bot. Madrid 70: 187–188. 2013) has been problematic. As the genus
was monotypic, there was no diagnosis (nomen specificum legiti-
mum) in his Species plantarum account (Linnaeus, l.c. 1753), but
there was reference to his 1738 work, along with Sloane (l.c. 1696,
1725), Ray (l.c.), Walther (l.c.), and Royen (Fl. Leyd. Prodr.:
223 [sub Bosia]. 1740).
Regarding the typification of the name Bosea yervamora, Lin-
naeus (l.c. 1753) gave the locality as “Habitat in Canariis insulis”,
but because he referred to Sloane’ s (l.c. 1696, 1725) accounts on
Jamaican plants, Linnaeus must also have assumed that the
species was present in the West Indies. Indeed, he had previously
(l.c. 1738) cited its occurrence as “Crescit in insulis Canariis, aliisque
Americae insulis” with reference to Plukenet (l.c. 1696). We believe
that Linnaeus’ s confusion on the locality arose because Plukenet
(l.c. 1696), who is considered the first to have described the Canarian
plant (as Arbuscula baccifera Canariensis […] Yerva-mora Hispa-
norum), mentioning only the Canary Islands as the locality, later
(Almagesti Bot. Mant.: 21. 1700) placed both this taxon and a
Jamaican-occurring species described by Sloane (l.c. 1696, 1725)
under the same polynomial. Linnaeus (l.c. 1753) continued to follow
Plukenet’ s second interpretation and treated the two species as a sin-
gle taxon. Sloane’ s polynomial has been identified as the West Indian
endemic Phyllanthus nutans Sw. (Phyllanthaceae), a species found
in the Cayman Islands, Cuba, and Jamaica, being relatively common
in Jamaica (Adams, Fl. Pl. Jamaica: 408. 1972; Proctor, Fl. Cayman
Islands: 441–443, t. 37. 2012; Falcón Hidalgo & al. in Int. J. Pl. Sci.
181: 288, 293–294, 298, 302. 2020).
Unfortunately, no material of either of these two species is found
in the Hortus Cliffortianus herbarium (Jarvis, Dataset: Clifford Her-
barium. 2016, https://doi.org/10.5519/0022031). Furthermore, Plu-
kenet’ s polynomial does not refer to any of his illustrations to
clarify the identity of this taxon; while his morphological description
is for a species with “Syringae caeruleae foliis, purpurantibus venis”,
which does not agree with the leaf morphology of either the Canary
Island amaranth or P. nutans.
Iamonico’ s (l.c.) lectotypification mentioned that “No specimens
of original material were found in the Linnaean and Linnaean-linked
herbaria.” He performed a thorough analysis on the material associated
with the name and made it clear that none was suitable for typification,
being not available to Linnaeus in or prior to 1753. After comparing
the Sloane (l.c. 1725) and Walther (l.c.) illustrations mentioned in
the protologue, Iamonico remarked that because the Sloane image is
more complete “we are designating it as lectotype of this name”. The
Sloane illustration seems to have been based on a single specimen in
