PLANTS FROM VARIOUS PLACES I8I 
plants. I designate as type number 870 of my herbarium. The 
fruit is not quite mature but evidently full grown, and further 
study may yet show it to be a valid species. 
Apocynum glaucum Nwd. nov. sp. 
Planta tota pallida et glauca, circa 2 dm. alta; flores cymosi 
in inflorescentia principali terminali et binis vel ternis aliis minoribus 
axillaribus: folia firma crassa et coriacea pro planta, 1-3 cm. 
longa, .5—2 cm. lata orbiculata vel late ovata vel ovalia, obtusa 
vel cum apice rotundato vel retuso-mucronulato; folia superiora 
perfecte ovalia 1-2 cm. longa .5—1.5 lata, binis faciebus perpallida 
subcoeruleo pallore; eorum margines minute revoluti; basis 
rotundata vel subcordata; petioli 2-3 mm. longi: flores breviter 
pedicellata; pedicelli 5 mm. longi: calix glauco-pallidus sicut 
folia, lobi ejus tubo longiores, calix totus %—% corolla minor: 
Corolla 5-6 mm. longa, lobis oblongis vel angustatis sublinearibus 
convoluta et contorta in apicem angustum 1-2 mm. longum; 
corolla anguste campanulata, ejus lobe minime divaricati, immo 
oblonga suburceolata. 
Whole plant whitish or pale bluish glaucous less than 2 dm. 
from the lowest leaf, but slightly branched: flowers in rather 
flat terminal cymes with 1 or 2 smaller clusters in the axils of 
the upper leaves: leaves firm rather thick and leathery, 1-3 cm. 
long, .5 to 2 cm. broad, orbicular to broadly oval, obtuse or roundish 
or slightly retuse at the apex with a mucronulate point at the end 
of the midrib: upper leaves perfectly oval, 1-2 cm. long, .5-1.5 
em. wide, pale on both sides, with a bluish glaucescence, (the blue 
tinge marked on the upper surface of young leaves) margins of 
the leaves slightly revolute, base rounded or subcordate, petiole 
2-3 mm. long: flowers short-stalked, pedicels 5 mm. long: calyx 
also bluish glaucous, its lobes narrowly oblong almost linear, 
lobes much longer than the tube, the whole % to % as long as 
the corolla: corolla 5-6 mm. long with oblong narrow lobes strik- 
ingly convolute and twisted in the bud forming a terminal point 
I-2 mm. long: corolla narrowly campanulate, limb not spreading 
giving the flowers suburceolate appearance. 
The whitish appearance of the whole plant marks it as easily 
superficially distinguishable from all others. The leaves are pale 
on the upper as well as on their lower surface. It is probably 
closely allied to A. cardiophyllum Greene, but the upper surface
