150 DR, F. E. FRITSCH ON THE 
(xi) Resin-canals present in the phloem throughout all parts of the plant; also in 
some cases in the cortex and pith of the petiole and in the pith of the stem; always 
present in the cortex of the stem. Development schizolysigenous; present in the 
embryo. 
(xii.) Fruit with longitudinal bundles of sclerenchyma traversing the pericarp 
and showing very definite layers of cells containing solitary crystals (except in Ortho- 
pterygium ?). 
The anatomical diagnosis of the two genera is as follows :— 
‘1. Juliania, Schlecht.—Cuticle of foliar epidermis usually striated; clothing-hairs 
usually of more than two (5-10) cells, long, pointed, with a swollen base, and restricted 
to the veins; glandular hairs fairly long with a well-marked stalk and a head with 
prevalent horizontal division; palisade-cells with straight walls, all the cells of equal 
size ; cortical resin-canals in the petiole (?); resin-canals generally present in the pith of 
the stem (except J. adstringens). 
2. Orthopterygium, Hemsl.—Cuticle of foliar epidermis smooth; clothing-hairs 
generally bicellular, rather short, not very pointed, without much swelling basally, and 
distributed fairly uniformly over the leaf-surface; glandular hairs short, somewhat 
globular in shape, with a short unicellular stalk and a head with numerous horizontal 
and vertical division-walls ; palisade-cells with finely undulated walls, cells of two sizes; 
tracheids in the smaller veins of the leaf with enlarged terminations ; no cortical resin- 
canals in the petiole (?); no medullary resin-canals in the stem. 
The anatomical diagnoses of the species are as follows :— 
JULIANIA ADSTRINGENS, Schlecht, 
(Pringle, n. 7243; Nelson, n. 1827 ; Rose & Hay, n. 5341; Langlassé, n, 319 bis.) 
Cuticle of upp. and low. epid. not very distinctly striated; stom. occur sparingly 
also on upp. epid.; hairs on mature leaf very long and much convoluted, composed of 
4-5 cells, sometimes unicellular ; glands with a short stalk and ovoid head; lowest: 
layer of spongy tissue tends to develop as palisade; clust, cryst. of leaf in particularly 
large idioblasts; no medullary resin-canals in the stem. : | 
JULIANIA MOLLIS, Hemsl, 
(Pringle, n. 6871.) 
Cuticle of upp. epid. distinetly striated, that of low. epid, scarcely striated ; hairs 
abundant, esp. on low. epid., mostly long, straight, pointed, and often composed of 10 or 
more cells; glands tend to be much elongated, gland, portion of numerous short cells 
having almost same diam. as stalk, which is made up of 1-2 much elongated cells; 
lowest layer of spongy tissue tends to develop as palisade; stone-cells markedly 
developed in cortex of stem ; medullary resin-canals in the stem. 
JULIANIA AMPLIFOLIA, Hemsl. 
(Rose & Hough, nn. 3735, 4755, 4819.) 
Cuticle of both epid. distinctly striated; hairs like those of J. mollis, but often bent 
and with a smaller number of cells; glands with a fairly long unicellular stalk and
