KEY TO JUNIPERUS. 



I. 



LEAVES ALWAYS ACICULAR, SPREADING IN WHORLS OF THREE, JOINTED 



AT THE BASE, LINEAR, RIGID, USUALLY SHARP-POINTED. 



t Leaves not decurrent on the branchlets. Staminate flowers, solitary in 



THE AXILS OE THE UPPER LEAVES. FRUIT COMPOSED OF THREE OR SIX SCALES, MARKED 

 AT THE APEX BY THREE RADIATING LINES OR FURROWS. SEEDS NORMALLY THREE, FREE. 



A. I. races with one white stomatic band above. 

 J. communis, Linmeus. Leaves to i inch long, slightly concave above, without any 

 trace of a green midrib near the base (except in rare cases). Fruit about \ inch in 

 diameter. In var. nana, leaves shorter, to ^ inch long. 



J. nipponica, Maxim. Resembling var. nana of Junipertts communis, but with leaves 

 markedly curved, deeply grooved above, and fruit without tubercles. 



J. rujida, Siebold aud Zuccarini. Leaves A to | inch long, very slender, deeply con- 

 cave above, with the margins inflexed, forming a narrow median groove. Fruit 

 about I inch in diameter. 



J. litoralis, Maxim. Like J. rir/ida in foliage, but with leaves densely imbricated and 

 larger ; glaucous fruit, J to inch in diameter. 



B. Leaves with two white stomatic bands above. 



* Shrubs with leaves spreading horizontally outwards (except in J. taxi/olia) 



FROM BRANCHLETS WHICH ARE USUALLY NOT PENDULOUS. 



J. Oxycedrus, Linnseus. Leaves \ to | inch long, gradually tapering from the middle 

 to the sharp-pointed acuminate apex ; upper surface with a conspicuous midrib, 

 about half the width of the white bands, which are equal in width to the marginal 

 green bands. 



J. taxi/olia, Hook, and Am. Leaves about i inch long, obtuse. Upper surface with a 

 midrib much narrower than the white bands, which are equal to or narrower than 

 the marginal green bands. 



J. macrorarpa, Sibthorp and Smith. Leaves $ to 1 inch long, tapering from the ba3e 

 to the sharp-pointed acuminate apex ; upper surface with a conspicuous midrib, 

 less than half the width of the white bands, which are broader than the marginal 

 green bands. 



J brevifolia, Antoine. Leaves oval-linear, very short, i to J inch long, with a rounded 

 or acute aud not acuminate apex ; upper surface with a conspicuous midrib, 

 and white bands broader than the green bands. 



** Trees with leaves directed towards the apices of the pendulous 

 branchlets. 



J. Cedrus, Webb and Berthelot. Leaves to | inch long, with a conspicuous midrib 

 above, about half the width of the white bands, which are equal in width to the 

 marginal green bands. 



J. formosana, Hayata. Leaves $ to | inch long ; upper surface with a midrib much 

 narrower than the white bands, which are broader than the marginal green bands. 



1 1 Leaves decurrent on the branchlets. Staminate flowers 8 to 6 in a head 

 on a scaly stalk. fruit much larger than in the other sections, composed of 6 or 

 9 ternate scales. seeds consolidated into a thick, globose, 8-celled boxy mass. 



J. drupacea, Labillardiere. Leaves J to \ inch long, widely spreading, rigid, sharp- 

 pointed ; upper surface with a broad green midrib, deeply furrowed near the base 

 and two broad white bands.
