21. Olyra yucatana A. Chase, l. c, p. 178. — Panicles contracted, 
often a second one from the upper sheath, 8—15 cm long, 2 em wide, 
axis and rachis scabrous; staminate spikelets on the lower branches and 
lower part of upper pistillate branches, 8 mm long including the seta- 
ceous tip of the lemma, palea about 2 mm shorter; pistilate spikelets 
15 to 17 mm long, the glume and sterile lemma scabrous, 7-nerved, 
8 mm long, and acuminate into flexuous setaceous tips as long again 
in the glume, half as long in the sterile lemma; fruit elliptical, obscurely 
pointed, 7 mm long, 4 mm wide, white and shining or old ivory toward 
maturity, the lemma silky-pubescent at base and on the margins. Culms 
tall, slender; sheaths mostly longer than the internodes, crisp-puberulent, 
blades 13 to 16 cm long, one-third as wide, abruptly acuminate at the 
apex, trapezoid-truncate at base. Known only from Yucatan. — This 
species was described and figured by Millspaugh & Chase (1903, 
Field Col. Mus, Bot. 3: 46) under the name Olyra semiovata Trin. The 
examination of Trinius’ type has shown this disposition of the Yucatan 
form to be erroneous. Type Gaumer 2372, no. 125941 Herb. Field 
Columbian Museum. ,Common at Chichankanab, Gaumer 1389, Poco- 
boch, Gaumer 2372.“ 
22. Olyra laterale (Presl) A. Chase, |. c., p. 179. — Panicum laterale 
Presl 1830, Rel. Haenk. I, 305. „Hab. in Peruviae montanis huanoc- 
censibus.“ The type, in the Presl herbarium in the National Museum at 
Prag, is labeled „Panicum laterale nov. sp. J. S. Presl“ and „Peruano 
montano oronocciensis.“ No staminate spikelets are present, the first 
glume is wanting in the pistillate spikelets, though Presl's description 
reads: „gluma inferiore brevissima,“ and again „Gluma inferior minima 
vix ulla.“ Judging from the description O. sarmentosa Doell is this 
species or closely allied to it. | 
23. Lithachne pineti (Wright) A. Chase, 1. c., p. 182. — Olyra pineti 
Wright 1862; Griseb. Mem. Acad. Amer. Sci. Art. VIII, 532. „Prope Monte 
Verde, inter pinorum folia dejecta 1536“ [Wright, Cuba]. The type is in 
the Grisebach herbarium; a duplicate in the Gray herbarium is a tuft of 
numerous very slender culms. Besides the label the latter sheet bears 
a slip in Wrigth’s hand „Olyra Pineti. Growing among masses of fallen 
pine leaves near Mr. Prevals, M. V. [Monte Verde] Aug. 22.“ — A deli- 
cate species apparently known only from the Wright collection. 
24. Raddia distichophylla (Schrad. A. Chase, l. c. p. 184. 
Strephium distichophyllum Schrad. 1829, 
in Nees Agros. Bras. 298.
