Cypress \Cy"press\ (s?"pr?s), n.; pl. Cypresses (-?z). [OE.
   cipres, cipresse, OF. cipres, F. cypr?s, L. cupressus,
   cyparissus (cf. the usual Lat. form cupressus), fr. Gr. ????,
   perh. of Semitic origin; cf. Heb. g?pher, Gen. vi. 14.] (Bot)
   A coniferous tree of the genus Cupressus. The species are
   mostly evergreen, and have wood remarkable for its
   durability.
   [1913 Webster]

   Note: Among the trees called cypress are the common Oriental
         cypress, Cupressus sempervirens, the evergreen
         American cypress, Cupressus thyoides (now called
         Chamaecyparis sphaeroidea), and the deciduous
         American cypress, Taxodium distichum. As having
         anciently been used at funerals, and to adorn tombs,
         the Oriental species is an emblem of mourning and
         sadness.
         [1913 Webster]

   Cypress vine (Bot.), a climbing plant with red or white
      flowers (Ipot[oe]a Quamoclit, formerly Quamoclit
      vulgaris).
      [1913 Webster]

Easton's 1897 Bible Dictionary:

Cypress
   (Heb. tirzah, "hardness"), mentioned only in Isa. 44:14 (R.V.,
   "holm tree"). The oldest Latin version translates this word by
   ilex, i.e., the evergreen oak, which may possibly have been the
   tree intended; but there is great probability that our
   Authorized Version is correct in rendering it "cypress." This
   tree grows abundantly on the mountains of Hermon. Its wood is
   hard and fragrant, and very durable. Its foliage is dark and
   gloomy. It is an evergreen (Cupressus sempervirens). "Throughout
   the East it is used as a funereal tree; and its dark, tall,
   waving plumes render it peculiarly appropriate among the tombs."
