Andes of Quito, Fr. Hall! in Hb. reg. Berol.; J. P. Coutbony l on a Dalea “ on the banks of the Machange, 
9,500 feet high.” — A very distinct species covering low shrubs with intricate masses of their hair-like 
stems, with scattered loosely flowered panicles ; whole plant filled with a reddish-yellow juice ; - flowers [504 (54)] 
scarcely more than 1 line long; scales very narrow, linear, irregularly and sparsely laciniate-fimbriate 
towards the tip ; seeds 0.7 fine long.

Var. 0. sphabrocyma : floribus globoso-cymosis ; calycis lobis acutiusculis seu obtusis. —Brazil, Prov. ,Goyaz, on

This is the first of a series of intricate, mostly Brazilian species, which includes nros. 54-58, and which will not be 
entirely cleared up until carefully studied in their native homes. The inflexed-pointed latinise and the naked capsule 
with the large intrastylar orifice seem to distinguish it sufficiently from (7. racemosa. Whether both forms described 
above, which seem to differ so materially in their inflorescence, really do belong together, must be decided after a fuller 
study of this whole group ; WeddelPs specimen seems to connect them. — Flowers 1—1| lines long ; cymes of one 5-8 
lines, glomerules of the other 4-5 lines in diameter ; seeds of the largest-flowered specimen 0.6-0.7 line long, obliquely 
ovate^ with a very short linear-oblong transverse hilum. 
'I 55. C. racemosa, Martius ; spread in several forms over a great part of South America, just like G. Grmovii over 
North America, and (7. planifiora over Asia and the Mediterranean regions ; it has been introduced with agricultural 
seeds into Europe, where it has given rise to many discussions, and has, to some extent, stimulated botanists to a fur¬ 
ther examination of this genus. —All the forms of this species are characterized by the loose racemose- 
paniculate inflorescence; calyx usually shorter than the deeply campanulate gradually widening tube ; [505 (55) ] 
laciniae commonly short, spreading or reflexed with indexed points; scales large ; ovarium ovate or obovate, 
the upper part being compact; styles stout with large, depressed, almost peltate stigmas; capsule commonly enveloped 
by the corolla, with 2-4 light-brown, oval, obliquely truncate or rostrate seeds, 0.6-0.7 line in length ; hilum short, 
linear, perpendicular or transverse, often with radiating lines on the umbilicus. I distinguish the following forms: — 
Var. a. Brasiliana. G. racemosa , Martius i Itin. I. 286; Choisy! Cusc. 181, t. 3, f. 1 ; DC. Prod. IX. 456: 
flowers with few or scarcely any glands, of a rather membranaceous texture and pale color, with very short and obtuse 
lobes of calyx and obtusish lobes of corolla ; flowers usually If lines long. —Common about Rio and generally in 
Brazil, on shrubs and herbaceous plants; Martius! 941; Booz ! Gaudichaud l Graham! Pohl l 5,100, in part;

Var. 0. miniata. G. miniata , Martiul! 1. e.; var. minuta, Ghoisy! 1. c.: flowers of a thicker texture, reddish, 
more or less glandulous.—Brazil, Martius! 1292; Ackermann! Mikan! Langsdorff! Pohl! 5,100 in part; Vauthier t

Vind. not HBK.—Flowers larger, lf-2 lines long, more membranaceous; lobes of corolla with acute inflexed points; 
scales as long as or often shorter than the tube. — Chili, Bertero! 205 in Hb. DC., 940 & 201 in Hb. Shuttleworth 
(nro. 940 in Hb. DC. is G. Chilensis'); Pceppig! Cl. Gay! 449 ; about twenty years ago it was introduced into Europe, 
but is apparently now lost; on Medicago sativa, sometimes in wet seasons destroying whole fields ; also parasitic on 
many other plants growing about such fields ; it has been observed in France, Piedmont, Switzerland, Germany, and 
Holland. 
Var. S. calycina. (7. suaveolens , Lechler fin sched.: flowers as large as in the last, often glandulous, with 
longer and obtusish lobes of calyx and corolla, both as long as the short and wide tube; dead corolla covering the 
capsule. — Brazil, Sellow ! in Hb. reg. Berol., Weddell! Riedel! Valdivia, Lechler ! 479.
