The information “27121 not 27120!” is written on the labels of the
isotypes
, including those from MO and RB, which we cite here for the first time. The description of the type specimens in
Steyermark (1978)
matches the morphology of these
isotypes
;
H.S. Irwin et al. 27120
(NY [photo]!) is a specimen of
Alternanthera martii
Fries (1920: 10)
.
Mitracarpus pusillus
is characterized by its cespitose herbaceous habit with prostrate to decumbent stems, terminal glomerules and circumscissile capsules. It is assessed as Endangered (EN) under the criteria B1ab(iii)+2ab(iii), with EOO =
102.9 km
² and AOO =
16 km
² (.kml file available at http://figshare.com/s/7d283c22772a11e58ef306ec4b8d1f 61). It is known from only two locations and is under continuing decline of suitable habitat due to eucalyptus forestry and agriculture (
Zappi
et al.
2014
).
