Juniperus communis - common juniper

A new method for the practical identification and recognition of trees -- and an important supplement to existing botanical methods.

The book is in two parts: Pictorial Keys and Master Pages. The Keys are designed for easy visual comparison of details which look alike, narrowing the identification of a tree to one of a small group -- the family or genus.

Then, in the Master Pages, the species of the tree is determined, with similar details placed together to highlight differences within the family group, thus eliminating all other possibilities. The details of the Oak trees on this plate are an example of the system.

All of the more than 1500 photographs were made specifically for use in this book and were taken either in the field or of carefully collected specimens. Where possible, details such as leaves, fruit, etc., appear in actual size, or in the same scale.

1500 orchid species are profiled in this authoritative, detailed, and carefully researched encyclopedia. Infinitely varied and hugely interesting, these strikingly beautiful plants are sumptuously illustrated with over 1000 photographs in a reference that no orchid lover can afford to be without. Isobyl la Croix is a scientist, plant hunter, and horticulturalist; her deep passion for orchids informs the plant selection and adds depth to the plant descriptions. The cultivation advice includes information about the orchid's native habitat—including elevation, geography, and climate. Recent developments in DNA analysis have led to some surprising findings with regard to the relationships between orchids, and the author has undertaken an extensive effort to bring all orchid names up-to-date to reflect the latest scientific thinking and taxonomy. From Acampe to Zygostates, no other serious reference approaches the depth and authority of this remarkable book.
