RONDELETIA LEUCOPHYLEA, HBK., var. calycosa. Habit and foliar 
characters of the species: inflorescence much contracted, subcapitate; 
bracts 7 to 12 mm. long, 3 mm. or less broad, acute: calyx-lobes sub- 
equal, subfoliaceous, lance-oblong, 6 to 8 mm. long, 1 to 2 mm. broad, 
obtuse or obtusish.— Mexico. State of Oaxaca: altitude 1650 m., 
December, 1900, Conzatti & Gonzdlez, no. 1127 (hb. Gr.) ; City of 
Oaxaca, altitude 1550 m., Conzatti, no. 970 (hb. Gr.). No differences 
other than the broader bracts of the inflorescence and the larger sub- 
foliaceous calyx-lobes are found to distinguish the variety from the 
species. 
The variety calycosa is cultivated in the Botanical Garden of the City 
of Oaxaca where it grows as a very graceful and decorative shrub. 
Bouvardia Conzattii. Shrub: stem and branches covered with a 
grayish bark; ultimate branchlets smooth and glabrous or minutely 
puberulent: leaves opposite, ovate to ovate-lanceolate, 1.5 to 4 cm. long, 
0.5 to 2 cm. broad, obtuse to subacuminate-acute, entire, slightly 
hirtellous on the margins, yellowish-green and puberulent above, paler 
and sparingly puberulent on the midrib and obliquely arched conspicu- 
ous lateral veins beneath, abruptly narrowed at the base into short 
densely puberulent 2 mm. long petioles; stipules lanceolate, 3 to 7 mm. 
long, lacerate-dentate : inflorescence terminating the stem and branches in _ 
close rather few-flowered corymbose cymes ; bracts subulate, and as well 
as the unequal linear-acute 3 to 5 mm. long calyx-lobes, hirtellous-pu- 
berulent especially along the margins: corolla red or yellowish-red, 13 
to 15 mm. long; tube cylindrical, glabrous on the outer surface, bearing 
within a ring of hairs one-third its length from the base; lobes short, 
ovate, acute, about 2 mm. long: stamens included ; filaments adnate to the 
corolla-tube two-thirds its length from the base; anthers subsessile: style 
glabrous: mature fruit not seen. — Mexico. State of Oaxaca: altitude 
1750 m., July-August, 1900, Conzatti & Gonzdlez, no. 1076 (hb. Gr.). 
Peederia Pringlei. Stem woody, twining, 6 m. or more in length; 
ultimate branches subcompressed, glabrous: leaves opposite, petiolate, 
ovate or slightly ovate-oblong, 2.5 to 5 em. long, 2 to 3 cm. broad, usually 
short-acuminate, acute, at first sparingly pubescent above, later more or 
less glabrate, hirsute-tomentulose beneath especially along the midrib and 
lateral nerves: flowers not seen : fruit elliptic-oblong, 10 to 12 mm. long, 
6 to 8 mm. broad, smooth and glabrous, bearing above the persistent 
calyx-teeth ; pyrenes separating by, and suspended on a filiform carpo-
