PAXICLE CHARACTERS OF SORGO 33 
but usually lighter at the apex ; second glume somewhat more concolorous from 
base to apex; caryopsis obovate-elliptic or elliptic, buff to dull brown (Ridg- 
way, cinnamon buff to sayal brown j ; scutellum jutting out somewhat at the 
base from the caryopsis ; sterile spikelets deciduous, occasionally with rudi- 
mentary stamens. 
McLean (Sugar Plant No. 0182). — Panicle open-cylindric ; longest rays one- 
fourth to one-half as long as the panicle ; rays standing out from the axis and 
usually straight ; first glume of fertile spikelet elliptic or more rarely obovate- 
elliptic or ovate-elliptic, black and shining or occasionally blue-gray, except 
toward the apex for one-sixth to one-fourth the length frequently light yellow : 
awn not protruding, but its apex occasionally visible at the apex of 
the second glume ; caryopsis extending about as far as the apices of the 
glumes or more rarely short of them, ovate-elliptic, or occasionally obovate- 
elliptic, flattened and often transversely wrinkled on the ventral side, com- 
monly obtuse at the base, somewhat acute at the summit, yellowish to 
reddish brown ; scutellum usually less than half as long as the caryopsis. 
curved at the base toward the ventral side ; style bases usually somewhat 
thickened ; sterile spikelets averaging longer than in the preceding variety and 
somewhat more persistent, sometimes one-fifth longer than the second glume 
of the fertile spikelet, and frequently reaching beyond its apex by as much 
as half their length ; a lemma together with lodicules or rudimentary stamens 
often present. 
Sugar Plant No. 0221087. — A selection made by the writer (6) from an im- 
pure accession of Gooseneck (S. P. No. 021612-17). Peduncle occasionally re- 
curved ; panicle somewhat more compact and panicle branches more appressed 
than in S. P. No. 01S2 ; fertile spikelet open somewhat wider ; lemma awned, 
the awn long, geniculate, the bend usually exserted, rather loosely twisted as 
far as the bend. 
Colman (Sugar Plant Xo. 021598-60$).— Somewhat similar to S. P. No. 01826. 
but panicle a little more compact and axis of panicle often shorter : first 
glume of fertile spikelet averaging elliptic, reddish brown, the apex frequently 
somewhat lighter, the lateral nerves sometimes slightly coarser than the 
others, but without the minute bristles ; caryOpsis light yellow, light orange, or 
reddish brown ; sterile spikelets falling off readily, light yellow or occasionally 
in part brown, rarely as long as the second glume of the fertile spikelet, 
though occasionally reaching somewhat beyond, the lateral nerves of first glume 
not hispid. 
Folger (Sugar Plant No. 021510), -formerly known as Folger's Early. — 
Panicle cylindric or subcylindric, more compact than in S. P. Xo. 021598-603, 
but sometimes some of the rays bowed : first glume of fertile spikelet similar to 
S. P. Xo. 021598-603. but black and shining and occasionally lighter at the apex, 
the lateral nerves scabrous-hispid : caryopsis commonly extending beyond the 
glumes, buff brown (approximately Ridgway, cinnamon buff) ; sterile spikelets 
light yellow, often mottled or spotted with dark gray or black, the lateral 
nerves scabrous-hispid. 
Orange (Sugar Plant No. 01059). — Panicle ovate-oval, or somewhat obovate : 
axis extending to the apex or shortened, occasionally to less than half the length 
of the panicle, always one and usually two or three nodes at the base of the 
panicle without branches ; branches more or less ascending, but some of them 
bowed especially near the extremities ; both glumes of the fertile spikelet 
usually marked with short longitudinal creases or corrugations at the base : 
glumes open about 45° or sometimes more than 90° ; first glume ovate- 
elliptic, more rarely elliptic or elliptic-ovate, strongly incurved at the sides, 
folded back above the callus, black and shining, or nearly black ; caryopsis 
usually extending beyond the apices of the glumes, sometimes rotated 90° in 
the spikelet, somewhat flattened on the ventral side : scutellum curved some- 
what toward the ventral side at the base ; style bases usually turned somewhat 
to the ventral half of the caryopsis ; sterile spikelets light yellow and dull 
brown, usually lightest at the base, persisting somewhat tenaciously. 
Several varieties similar to the last differ chiefly in color of glumes and 
caryopsis. Among these, varieties designated by the following names have 
been examined: Silvertop (Sugar Plant Xo. 021618-23); Albaugh, formerly 
known as Albaugh Early (Sugar Plant Xo. 021645-50) : Texan, formerly known 
as Texas Seeded Ribbon (Sugar Plant Xo. 021604-09) ; and Jones, formerlv
