76 The Philippine Journal of Science isu 
has been more recently described as F. confusa by Mr. Elmer. The Guam 
specimens are sterile, but agree very closely with our Philippine material. 
In addition to the species enumerated above, what I take to be Cecropia 
palmata Willd. is represented in the collection (G. E. S. S90), from a 
cultivated plant at the Experiment Station; a native of tropical America, 
recently introduced. 
URTICACEAE 
BOEHMERIA Jacquin 
BOEHMERIA NIVEA (Linn.) Gaudich. Bot. Freyc. Voy. (1826) 499. 
Urtica nivea Linn. Sp. PI. (1753) 985. 
Boehmeria tenacissima (Roxb.) Gaudich. 1. c. 500; Safford 200. 
G. E. S. 205, indicated as widely distributed, but probably introduced, 
although Safford claims it to be indigenous. 
A native of tropical Asia, now widely distributed in cultivation. 
I do not consider that the differences between Boehmeria nivea and B. 
tenacissima are sufficiently distinct to warrant separating them. The Guam 
plants belongs, undoubtedly, to the latter form. See Robinson, Philippine 
Journal of Science 7 (1911) Botany 4. 
ELATOSTEMA Forster 
ELATOSTEMA STENOPHYLLUM sp. nov. 
Erectum, glabrum, simplex, 15 ad 25 cm altus; foliis alternis, 
lanceolatis, utrinque subaequaliter angustatis, usque ad 6 cm 
longis, apice obtusis vel acutis, basi leviter inaequalibus, acutis, 
obscure 3-plinerviis, margine leviter distanter crenato-dentatis ; 
inflorescentiis $ solitariis, breviter pedunculatis, subglobosis, 5 
ad 6 mm diametro; floribus 4-meris. 
A simple, erect, glabrous, rather slender plant 15 to 25 cm 
high, the stems and leaves with numerous cystoliths. Leaves 
alternate, lanceolate or narrowly lanceolate, chartaceous, 3 to 6 
cm long, 5 to 12 mm wide, about equally narrowed at both 
ends, the apex blunt or acute, not at all acuminate, the base 
somewhat inequilateral, gradually narrowed, acute, not at all auri- 
culate, the margins slightly and distantly crenate-serrulate ; 
nerves 3, slender, the basal pair leaving the midrib shortly above 
the base, anastomosing with the distant lateral nerves above; 
stipules narrowly lanceolate, acuminate, 3 to 4 mm long. Stam- 
inate inflorescences axillary or in the axils of fallen leaves, 
solitary, their peduncles about 2 mm long, the heads depressed- 
globose, 5 to 6 mm in diameter, the involucral bracts green, 
oblong to suborbicular, about 3 mm long. Male flowers nu- 
merous, the subtending bracteoles usually 3, narrowly obovate- 
oblong, rounded-truncate, very obscurely ciliate at the apex; 
pedicels slender, 3 mm long. Calyx-lobes 4, oblong-elliptic, apicu-
