xxxvi A NATURALIST IN WESTERN CHINA 



Labiate. — A few small shrubs of Salvia in Texas, and the genus 

 Elsholtzia, with several species in eastern continental Asia, represent 

 the woody plants of this family in our two regions. 



SoLANACE^. — Species of Lycium and Solanum, which occur in 

 each of the two regions, are the only woody plants of this family. 



ScROPHULARiACE^. — Of this family Leucophyllum, a small 

 shrub of western Texas, is the only woody plant in eastern North 

 America, but in eastern continental Asia it is represented by the 

 important genus Paulownia, of several species of large trees, and by 

 Brandisia. 



BiGNONiACEiE. — In this family Campsis and Catalpa are 

 common to the two regions. The monotypic Chilopsis, and Aniso- 

 stichus and Crescentia occur only in the southern United States. 

 Oroxylum, Dolich an drone, Stereospermum, and Radermachera are 

 Chinese and not American. 



Gesnerace^. — iEschynanthus and Lysinotus,with woody species 

 in China, are the representatives of this family in the two regions. 



Myoporace.^. — A species of Myoporum of southern China is 

 the representative of this small family in the two regions. 



Rubiace/E. — Of this family the American woody representatives 

 are Cephalanthus, the monotypic Pinckneya, Exostemma, Genipa, 

 Randia, Catesbgea, Hamelia, Guettarda, Erithalis, Chiococca, 

 Strumpfia, Psychotria, Morinda, and Ernodea. Of these Cephal- 

 anthus, Randia, Guettarda, Psychotria, and Morinda occur also in 

 China, where also are woody representatives of Adina, Luculia, 

 Wendlandia, Hedyotis, Musssenda, Adenosacme, Myrioneuron, 

 Webera, Gardenia, Diplospora, Antirrhcea, Conthium, Ixora, 

 Damnacanthus, Lasianthus, Paederia, Hamiltonia, Leptodermis, 

 Serissa, Emmenopterys, Dunnia, Pavetta, and Uncaria. 



Caprifoliace^. — Of the ten genera of woody plants of this 

 family found in the two regions, Dipelta, Leycesteria, Kolkwitzia, 

 and Abelia (with a species in Mexico) occur only in China. Of the 

 other genera, Sambucus, Viburnum, Symphoricarpos, Linnaea, 

 Lonicera, and Diervilla are common to the two regions. Symphori- 

 carpos is chiefly American, with a single Chinese species, and Vibur- 

 num, with some seventy species, is richer in China than in eastern 

 continental America, although the American species grow to a 

 larger size and are more ornamental. Lonicera is poorly represented 

 in eastern North America with twelve species, while in eastern 

 continental Asia more than one hundred species are recognized, the 

 region of their greatest segregation being on the mountains of the 

 central and western provinces.
