Le miocene lacustre, traverse ä Chinchilla par le cretace, 

 forme toute cette region. 



Les conditions climatiques sont assez remarquables. Les tempe- 

 ratures varient entre 41,8^ et —11,5°, il y pleut seulement pendant 

 64 jours, donnant 363 millimetres d'eau, dont 63 pendant le prin- 

 temps, 54 en ete, 111 en automne et 136 pendant l'hiver. En cons6- 

 quence l'air est trös sec. C'est ce qu'indiquent les chiffres 72 pour 

 l'hiver, 55 pour le printemps. 38 ä l'ete et 64 ä l'automne. 



Tout cela ddtermine le caractere de la Vegetation se rattachant 

 tout ä fait ä celle des steppes iberiques, se distinguant a peine par 

 quelques especes speciales. 



Les arbres sont tres rares; le Ptiiits Pinea et le Quercus Hex 

 rompent ä Garcia Ruiz la monotomie du paysage; aux bords 

 du canal Maria Christina vegetent les Populus tremula, alba, 

 canesceriSj nigra et VUlmtis canipestris.

 George Forrest consists of a numerical catalogue of the first 

 1120. The valuable notes made by Mr. Forrest are quoted in füll 

 from his field labeis. Dysophylla communis, Coli, et Hemsl.. is

A Short introduction deals with the climate, geology, topogra- 

 phy and floral characteristics of the province. Following this is a 

 dichotomous key to the Natural Orders of flowering plants, ferns 

 and fern allies represented in the region and an enumeration of 

 all the species with their localities, (and in the case of the former) 

 the colour of their flowers and time of flowering. Each Natural 

 Order and genus is preceded by a key, similar to that alread}'' men- 

 tioned, so that an unknown plant may be referred to its Natural 

 Order, genus and species by anyone possessing a fair knowledge of 

 botany. The systematic order of the Genera plantarum of Bent- 

 ham and Hooker is followed, and the nomenclature is that of the 

 Index Kewensis. The following new species are described, the 

 type specimens being preserved in the Herbaria of Kew and 

 Hongkong: 



Polygala nimborum. Dünn, Eurya aniplexifoUa, Dünn, Cladrastis
