SYSTEMATIC BOTANY. 



Tlieso cliaracteis lead you iu the key t(j the onler Crucifer;e, hut it is not easy to decide 

 farther, hecause you have not tlie fruit. Look for the pods a few weeks later, and you 



M ill tiiid them long and flat, as represented in the 

 figure at e on the left. You can then determine 

 the name of the plant. The seed pods here 

 figured will help you in determining some of the 

 plants in this order. 



The curious flower depicted helow is another 

 early bloomer. You must cut the flower open 

 and study it carefully. The four — sometimes 

 five — petals are joined together, and bear upon 

 the short tube the four stamens which bug tl)e 

 pistil tightly and form a beak like that of a bird. 

 The ovary does not adhere to the calyx, and if a 

 seed pod is partly grown, it will be easy to see 

 that the seeds grow upon a central placenta. 

 Turning to the key you are called upon to de- 

 cide whether the stamens are opposite the lobes 

 of the corolla or not. They certainly are op- 

 posite, so the order Primulaceie is evidently 

 ^vhere our plant belongs. The pretty little for- 

 eigner Anagallis is here figured, and it will be 



Ui'PKR Fir;. — a, indehiscent 

 pod of Rapbauus Raphauis- 

 iruiu; /», pud (silide) of Cap-

 Capsella divaricata; d, pod 

 (silique) of Tropidocarpum, 

 flattened contrary to the jiarti-

 of Lepidinm nitidum, and two partitions from wbioh the valves have fallen, L\^L\^^ 

 showing that there was one seed iu each cell; g, pod of Lepidiuni latipes, \llf 

 showing the broad pedicel which suggested the specific name; A, a branch \\\\V
