202 INTRODUCTION 
difficulties in photographing most very small objects that I now employ this method 
only under exceptional circumstances (cf. the illustration of the positions of flowers 
of Lycium barbarum JZ. in Fig. 79). 
Fic. 79. Lyctum barbarum, L. (from a photograph three times the natural size). (1) Flower in the 
first condition: the filaments of the dehisced stamens are upwardly directed, the style with the stigma 
ready for pollination is bent down. (Condition for cross-pollination.) (2) Flower in the second condi- 
tion: stamens and stigma are so close together that spontaneous self-pollination results from direct 
contact. ¢, corolla; a, anther; s, stigma. 
I have therefore returned to the habit of drawing flowers. A drawing gives 
a better idea of what is seen than the best description. 
Like all research, the study of the ‘ most interesting branch of lovable science ’— 
Flower Pollination—is full of trouble. But the labour bestowed is amply repaid by 
the result, by deep penetration into the ‘secrets of the flowers.’ ‘Each one of the 
beautiful flower faces,’ says Hermann Miiller (‘Alpenblumen,’ p. 23), ‘which we 
were wont to marvel at with a sad feeling of resignation as so many mysteries for 
ever veiled, now looks upon us inspiring hope, and stimulating us in friendly wise to 
cheerful perseverance, as if it would say,—Only venture to come to me, and in true 
love make yourself acquainted with me and all my conditions of life, as intimately as 
you may, and I am ready to let fall the veil that hides me, and to trust myself and 
all my secrets to you !’
