ABSTRACT. Briza L. (Poaceae, Pooideae, Poeae) is a
genus with a controversial circumscription, being
either considered sensu lato, including Eurasian and
South American species (e.g., Longhi-Wagner,
1987), or sensu stricto, including only four Eurasian
species and being considered closely related to the
South American species, forming the Briza complex
(Matthei, 1975). According to recent phylogenetic
analysis, Briza should be accepted sensu stricto,
with four Eurasian species, as proposed by Matthei
(1975) and other authors. The American species,
which were previously published under Briza s.l. or
under the genera Calotheca Desv., Chascolytrum
Desv., Erianthecium Parodi, Gymnachne Parodi,
Lombardochloa Roseng. & B. R. Arrill., Microbriza
Parodi ex Nicora & Rúgolo, Poidium Nees, and
Rhombolytrum Link, should be included within
Chascolytrum, the oldest generic name published
for the American species of the complex. As a result,
the following 13 new combinations are proposed in
Chascolytrum: C. ambiguum (Hack.) Essi, LonghiWagner & Souza-Chies, C. bidentatum (Roseng., B.
R. Arrill. & Izag.) Essi, Longhi-Wagner & SouzaChies, C. brachychaetum (Ekman) Essi, LonghiWagner & Souza-Chies, C. brasiliense (Nees ex
Steud.) Essi, Longhi-Wagner & Souza-Chies, C.
brizoides (Lam.) Essi, Longhi-Wagner & SouzaChies, C. bulbosum (Parodi) Essi, Longhi-Wagner
& Souza-Chies, C. calotheca (Trin.) Essi, LonghiWagner & Souza-Chies, C. itatiaiae (Ekman) Essi,
Longhi-Wagner & Souza-Chies, C. koelerioides
(Trin.) Essi, Longhi-Wagner & Souza-Chies, C.
monandrum (Hack.) Essi, Longhi-Wagner & SouzaChies, C. poomorphum (J. Presl) Essi, LonghiWagner & Souza-Chies, C. rhomboideum (Link)
Essi, Longhi-Wagner & Souza-Chies, and C. uniolae

Poidium brasiliense Nees ex Steud., and Rhombolytrum berteroanum E. Desv. are lectotypified.
Key words: Briza complex, Chascolytrum, Eurasia, Gramineae, South America.
The genus Briza L. (Linnaeus, 1753; Poaceae,
Pooideae, Poeae) was published with three European
species, B. maxima L., B. minor L., and B. media L.
Another Old World species, B. humilis M. Bieb., was
added later, in 1808. Several new South American
species were afterward described under Briza or
under the genera Chascolytrum Desv., Calotheca
Desv., Poidium Nees, Lombardochloa Roseng. & B.
R. Arrill., and Microbriza Parodi ex Nicora & Rúgolo
(Nicora & Rúgolo de Agrasar, 1981). Further
taxonomic treatments (e.g., Ekman, 1913; Parodi,
1920; Rosengurtt et al., 1968, 1970; Longhi-Wagner,
1987) accepted a broad circumscription for Briza,
some including sections or subgenera for Briza to
accommodate such great morphological variability.
Matthei (1975) published a revision of Briza and
related genera, jointly referred as the Briza complex,
using morphological, anatomical, and cytological
data. This author accepted Briza s. str., restricted to
the Eurasian species, and distributed the American
species among the genera Calotheca, Chascolytrum,
and Poidium, a move that was followed by other
authors (Smith et al., 1981; Soreng et al., 2003).
Nicora and Rúgolo de Agrasar (1981) described
the genus Microbriza for two species previously
accepted under Briza or Poidium: M. brachychaete
(Ekman) Parodi ex Nicora & Rúgolo and M.
poomorpha (J. Presl) Parodi ex Nicora & Rúgolo [as
‘‘poaemorpha’’]. Additionally, Nicora and Rúgolo de
Agrasar (1981) accepted Briza with a different
circumscription from that proposed by Matthei
(1975), including not only the Eurasian species, as
in Matthei (1975), but also the American species
previously described under the genus Chascolytrum

New Combinations in the Briza Complex
and a portion of the species described in Poidium.
Nicora and Rúgolo de Agrasar (1981) accepted the
genera Calotheca, Poidium, and Rhombolytrum Link
for the remaining species of this complex.
Bayón (1998) published a cladistic analysis of the
Briza complex based on 32 morphological characters,
resulting in the acceptance of the genera proposed by
Nicora and Rúgolo de Agrasar (1981), with similar
circumscription. Recently, Essi et al. (2008) performed a phylogenetic analysis of the Briza complex
based on molecular data that included three other
related genera, Erianthecium Parodi, Rhombolytrum,
and Gymnachne Parodi. This study resulted in the
acceptance of Briza s. str. with four Eurasian species,
and in the proposal of a new circumscription for the
genus Chascolytrum, including all the accepted South
American species previously assigned to the other
genera cited above. The necessary new combinations
resulting from this new circumscription are proposed
in the present work.

Notes. According to Matthei (1975), the holotype
of Poidium brasiliense Nees ex Steud. (Sellow 4848 at
B herbarium) was destroyed; therefore, he proposed a
neotype, Glaziou 6774 (P). However, this specimen
belongs to Briza itatiaiae Ekman, which Matthei
(1975) placed in synonymy. In the present study B.
itatiaiae is accepted as Chascolytrum itatiaiae (Ekman) Essi, Longhi-Wagner & Souza-Chies. Nicora
and Rúgolo de Agrasar (1981) had already noticed
this problem and indicated there was a fragment of
the holotype of P. brasiliense Nees ex Steud. at the
herbarium BAA. This material was analyzed and
confirmed as belonging to the original type collection
of P. brasiliense Nees ex Steud. Another fragment of
Sellow 4848 was found at US. The neotype proposed
by Matthei (1975: 112) cannot be accepted, and
furthermore it belongs to B. itatiaiae according to the
circumscription accepted here. The specimen Sellow
4848 (BAA) is now proposed as a lectotype. The
fragment from BAA was chosen for lectotypification
because it is the material discussed in detail
(including leaf anatomy) by Nicora and Rúgolo de
Agrasar (1981).

Notes. Two syntypes were cited in the protologue
of Poa koelerioides Trin., one collected by C. G.
Bertero (C. G. Bertero 947) and another attributed to
Prescott (Prescott 1832). The latter specimen is
considered by Soreng et al. (2003) as being from
the same collection C. G. Bertero 947. The collection
C. G. Bertero 947 is also included in the protologue of
Rhombolytrum berteroanum E. Desv. as one of the two
syntypes (the other specimen is the collection Gay
298, P, duplicates K, US-90608 [image seen]). The
specimen seen at P (Bertero 947) is well conserved
and matches with the original description of P.
koelerioides Trin. It also matches with its synonym R.
berteroanum E. Desv., but for this last species the
collection Gay 298 was preferred in order to avoid
using the same lectotype for two different names.
