a Vienna, 1847.—This second part of the 4th supplement was made 
to anticipate the first, which, we believe, remained unpublished at the 
untimely death of the accomplished Endlicher, in March last. Begin- 
ning with the Coniferze, which the author had recently made the subject 
of a special] study, the present a goes on through the Exoge- 
nous Apetalous orders only. er several of the orders, such as the 
Betulacee, Cupulifere, Polygonce, Daphnoidee, and Proteaceae, a 
complete systematic enumeration of species is given. R.

industry of its lamented author. It treats, Ist, the Cupressinea, which 
are divided into five groups. genus Libocedrus, is established for 
one New Zealandian and two Chilian trees, formerly referred to Thuja ; 
and Biota, a section of Thuja of Donn is raised to the rank of a genus, 
including the oriental Thuja ey mae L., and T. pendula, Lamb. 
Thuja proper is thus left as a N. American genus, including T. occi- 
dentalis, L., T. plicata, Donn, and T. gigantea, Nuit. yar 3 genus 
Chamecyparis (Chammpence, Zucc., Retinospora, Sieb. and Zucc.) is 
adopted for our Cupressus thyoides, the C. Natkate: ensis of Geanai and 
the Mexican C. thurifera, ie three Japanese species, which form @ 
rate section. In Taxodium, T. microphyllum, Brongn., and 
adscendens, Brongn., are hepre as specifically distinct from T. distichum.
