preserved ; it is found in all the cells of the head in the form of globular drops of an 
opaque yellowish-white appearance (fig. 1, A, B), one or more drops being present in 
each cell; the secretion is insoluble in Eau de Javelle, absolute alcohol, and xylol. 
In Juliania amplifolia the glands have a fairly long unicellular stalk and an oval 
elongated head, in which vertical division-walls are comparatively rare (fig. 1, B); the

A.—Juliania mollis (Pringle, n. 6871), surface-view of lower epidermis, showing stomata, clothing-hairs, and two 
glandular hairs, one of them with resinous contents (r). (x 200.) 
B.—J. amplifolia (Rose & Hough, n. 4755), lower epidermis with stomata and two glandular hairs, one of them 
with resinous contents (7) ; clothing-hairs omitted. (Cuticular striation not shown.) (x 960.) 
C.—J. amplifolia (Rose & Hough, n. 4755), surface-view of upper epidermis, showing bent, multicellular clothing- 
hairs. (Cuticular striation not shown.) (x 360.) 
D.—Orthopterygium Huaucui, surface-view of lower epidermis, showing stomata, unicellular hairs, and a glandular 
hair. (x 305.) | 
E.—Juliania adstringens (Privgle, n. 7 243), a detached glandular hair. (x 290.) 
F.— Orthopterygium Huaucui, a detached glandular hair. (x 360.) 
diameter of the head frequently only slightly exceeds that of the stalk. In J. mollis 
the glands tend to be more elongated than in J. amplifolia, the glandular portion having 
very much the same diameter as the stalk; the latter consists of one or two much- 
elongated cells contrasting greatly with the often numerous short cells which constitute 
the head; vertical division-walls are rare in the latter (fie. 1, A). It is only the markedly
