LI. MYRTACEiE. 
611 
Leaves long-lanceolate or linear, not very thick, the oblique veins fine but 
often conspicuous. Calyx rarely above 3 lines diameter. 
Pedicels slender. Operculum more or less rostrate. Fruit-rim very 
convex or conical. 
Bark smooth, white, deciduous 37. E. rostrata. 
Bark rough, dark, persistent or falling off in fragments 38. E. exserta. 
Operculum 2 to 4 times as long as the calyx-tube, obtusely conical. 
Fruit-rim very convex or conical 39. K. tereticornia. 
Subsekies III. Subexsertae. -Peduncle* axillary or lateral, or also the upper ones more or 
less paniculate, terete or flattened, several-flowered. Calyx-tube broad at the orifice. Fruit 
turbinate, the orifice not contracted, the capsule level nr slightly sunk, the valves often protruding 
when open. 
This subseries differs from the Exsertee and the Inclusce chiefly in the fruit. — Benth. 
Leaves broad, with very diverging veins and distinctly reticulate. 
Flowers nearly sessile or on short thick pedicels. Operculum hemi- 
spherical, short 40. IS. platyphylla. 
Flowers small, distinctly pedicellate. Operculum conical 41. E. alba. 
Leaves mostly lanceolate, rather thick, the veins fine or obscure, oblique 
and irregular. Operculum conical 42. E. Stuartiana. 
(See also 23, E. siderophloia, which has nearly the fruit of the Subexsertce , but with very 
different anthers. — Benth.) 
Leaves ovate-lanceolate to lanceolate, with very numerous, fine, close, 
parallel veins. 
Operculum conical, about as long as the calyx-tube. Leaves usually 
narrow. Flowers nearly sessile 43. E. saligna. 
Operculum much longer than the calyx-tube. Leaves usually broad- 
lanceolate. Flowers distinctly pedicellate. 
Calyx-tube under Jin. diameter 44. E . resinifera . 
Calyx-tube 6 to 8 lines diameter 45. E. pellita. 
Subsekies IV. Incluste . — Umbels usually several-flowered, axillary or lateral and solitary 
or several together, in lateral clusters or very short panicles, and then sometimes reduced to 1 or 2 
flowers each, the peduncles terete or rarely flattened. Fruit more or less contracted at the orifice, 
the capsule sunk, the valves not protruding , excepting their poin ts when, acuminate by the split base 
of the style. 
Umbels solitary and simple, axillary or the upper ones almost paniculate. 
Operculum hemispherical or flat. Peduncles with several pedicellate 
flowers. Calyx Jin. long, narrow. Stamens long and red. Fruit long, 
with a distinct neck 49. E. phcenicea. 
Umbels several together, on very short lateral peduncles, forming short 
panicles or clusters ; operculum very short and flat. 
Leaves mostly opposite, large, broad, thick, and rigid. Umbels irregular, 
each often reduced to 1 or 2 flowers. Calyx 4 lines diameter or more 46. E. yrandifolia. 
Leaves from broadly cordate and opposite to broadly lanceolate, irregu- 
larly and conspicuously veined. Umbels many-flowered. Pedicels 
long. Calyx under 3 lines diameter 47. E. clavigera. 
Leases all narrow-lanceolate, with more regular veins. Pedicels shorter. 
Calyx small (the whole inflorescence sometimes reduced to an 
apparently simple cluster) 48. E. tesselaris. 
(See also 27, E. crebra, and its allies amongst Micrantherce, which have frequently a compound 
inflorescence, and a similar fruit, but a conical operculum and very small anthers.) 
Subseries V. Corymbosse.— Flowers usually large, (the umbels or very rarely heads j all 
in a terminal corymbose panicle, or rarely a few of the lower ones axillary. Fruit often large, 
more or less urceolate, the capsule deeply sunk. Seeds usually large, flat, with acute edges, often 
more or less expanded in a variously -shaped wing. 
Leaves opposite, sessile, cordate. Branehlets and calyx bristly. Leaves 
small. Fruit J to fin. long 50. FI. setosa. 
Leaves alternate, peltately attached to the petiole above the base, broadly 
ovate 52. A. peltata. 
Leaves alternate, petiolate, broadly ovate. Fruit globose, truncate or with 
a very short neck 53. E. latifolia. 
Leaves ovate-lanceolate or lanceolate, acuminate, with numerous fine, 
close, almost transverse veins. Fruit J to fin. long, not ribbed. Seeds 
more or less winged 55. E. corymbosa.
