Lectotypus (designated here): BRAZIL. Goiás: inter Cabeceiras do Rio Sambambaia et Le Pouzo de Barbatimao , Glaziou 20848 ( BR [ BR0000005314171 ] digital image!; iso-: K [ K000531970 ] digital image!, R [ R000074467 ] digital image!, S [ S-R-9570 ] digital image!).

Perennial herb, 10-, with rizhome and xylopodium. Stems spreading, terete, striate, 0.5- diam., with short hairs. Leaves with stipules elliptic; 3- long; petiole 1.5- long; blade broadly elliptic or elliptic, 1-2.5 × 0.5-, margin entire, apex apiculate, adaxial surface glaber, abaxial surface glaber or with appressed hairs on the nerves. Inflorescences axillary, 4-8-flowered, peduncles 3.5- long. Flowers white, with pedicels 1-, pubescent; receptacle with rigid appressed hairs. Floral tube campanulate, long, glaber; sepals ca. long; petals ca. long; stamens with filaments long and anthers long; style ca. divided at the apex. Fruit not seen.

Distribution and habitat. – Crumenaria glaziovii grows in grazing areas of the states of Goiás and Minas Geráis of Brazil (de LIMA, 2010), at elevations from 600 to 1050 m.

Phenology. – Crumenaria glaziovii flowers in October and November.

Etymology. – Crumenaria glaziovii was named in honor of Auguste François Marie Glaziou (1828-1906), a French botanist and landscape designer, who collected the type specimen.

Discussion. – Crumenaria glaziovii is related to C. decumbens with which it shares axillary inflorescences and slender stems, but differs in its perennial habit.

The holotype at B (negative at F [barcode] F0 BN005861 digital image!) was destroyed during World War II; we choose the isotype at BR as lectotype which matches the diagnostic characters.

Additional specimens examined. – BRAZIL. Goiás: Chapada dos Veadeiros , ca. N.W. of Veadeiros, road to Cavalcante, 22.X.1965, Irwin & al. 9478 ( NY).
