208 MEMOIRS OF THE NEW YORK BOTANICAL GARDEN [VOL. 35
1-3 mm, the anthers of all subhomomorphic (or the 3 abaxial slighriy shorter),
the body 4.2-6 mm, the biporose beak 0.5-0.7 mm; ovary strigulose; style 0.6-0.9
mm diam; ovules (of typus) ±134.
Pod unknown in mature state, apparenriy ±7-14 cm, the compression, texture
of valves, mode of dehiscence and seeds aU unknown.
Margins of woods and thickets, 1600-2100 m, CordiUeras Occidental and Cen­
tral from vicinity of MedeUin s. to Popayan, in Antioquia, Valle and Cauca,
Colombia.—Fl. IX-III.
The material cited below, with which we confidenriy associate the type-collec-
rion of Chamaefistula toroana, is reminiscent of some forms of S. papillosa, S.
dariensis and especially ofthe thinly pubescent Venezuelan races of 5. oxyphylla,
but is not exactiy like any of them, and we are at a loss to dispose of h systematically
due to our ignorance of the fruit. Unripe pods of Cuatrecasas 20529 have
a suggestion of ridges along the sutures such as occur in true S. oxyphylla, but
those of the typus of Ch. toroana appear to have been fleshy as in S. dariensis
var. smaragdina. Neither has papiUose valves, which can normally be recognized
at an early stage of maturity. All other specimens seen have flowers only and
seem to differ materially from S. oxyphylla var. oxyphylla only in the less zigzag
inflorescence-axis and shghtly larger anthers. In this connection a fruiting coUec­
rion from the lower Cauca valley (Pto. Valdivia, 2.II.1943, Br. Daniel 3392, US)
may be highly significant, but until flowers can be obtained from the same place
the identity of the plant must remain doubtful. The fohage of Bro. Daniel's senna
is persuasively suggestive of Chamaefistula toroana while the pod and seeds
seem indistinguishable from those of S. oxyphylla. If the ripe fruit of montane
Ch. toroana proves to be the same, the material cited below may all be referable
to S. oxyphylla sens, lat., filling in the distributional gap between var. oxyphylla
as treated in this revision and Ecuadorian var. hartwegii. We lack data to resolve
this problem.

BACILLARES INDETERMINATAE
Glaziou 12616 (BR, K), without further locahty than "Environs de Rio Janeiro,"
but, according to Glaziou's Liste and label at P (coU. 8.VIII.81) from Santa
Quiteria, Minas Gerais (now become a suburb of Belo Horizonte).—At first sight
suggesring S. macranthera var. macranthera, of which it has the androecium and
large flowers (long petals to ±23 mm), but the sepals lanceolate subacute up to
10x3 mm. The sepals suggest C. acutisepala, which differs in the smaU abaxial
anthers and in the basaUy subsymmetric leaflets. The specimens can be assimi­
lated into no described species, and are best left unnamed untU matching material,
accompanied by rehable locahty-data, are procured.
J. T. Baldwin Jr. 3268 (US): BRAZIL. Amazonas: Providencia, Rio Negro,
12.11.1944 (fl).—Resembhng in the small lvs (distal lfts asymmetricaUy elliptic up
to 7 cm) both S. rupununiensis and S. wurdackU, but differing from both in having
only 1 periolar gland and in detaUs of the androecium. The latter is functionally
7-merous, as that of S. rupununiensis, but the 3 abaxial anthers (±5 mm) are
markedly shorter than the 4 median ones (7-8 mm). The androecium of 5. w^ur-
