A general account also appears in his Lehrbuch der Botanik 

 (18). Schleiden and Vogel (234), 1839, 1842, studied the 

 seeds of several representative Leguminosae. Pringsheim 

 (202), 1848, in his inaugural dissertation, describes the testa 

 in Pisum sativum and Vicia Faba, giving some excellent 

 illustrations; Adolfo Targioni-Tozzetti (257), 1855, of Vicia 

 polyantha. Russow (212. 213), 1871 and 1872, in connection 

 with his work on the comparative anatomy of Marsiliaceae, 

 refers to the structure and nature of the Malpighian cell, 

 especially the light line. Sorauer (250), 1872, Le Monnier 

 (148), 1872, and Wiesner (285), 1873, incidentally refer to 

 the structure of some leguminous seeds. 



Strandmark (254), 1874, studied the seeds of the orders 

 Cucurbitaceae, Solanaceae, Resedaceae, Capparidaceae, 

 Geraniaceae, Convolvulaceae, Hydrophyllaceae, Violaceae, 

 Caryophyllaceae, Malvaceae, Cruciferae, and eleven genera 

 oi Leguminosae. Nobbe (190), 1876, gives some details of 

 a few economic species. In 1874, Sempolowski (247) gave 

 a complete and accurate description of the genera Lupinus, 

 Vicia, Ervum, Pisum, Trifolium, Medicago, Melilotus, 

 Omithopus, Anihyllis, Trigonella, and Onoh'ychis, Chalon 

 (39), 1875, published an extended paper, the first part of 

 which is devoted to the structure of the testa, and the 

 second to the endosperm. 



To Haberlandt (83), 1877, we owe an account of the de- 

 velopment and structure of the seeds of the genus Phaseolus. 

 Giinther Beck (8), 1878, described the testa, endosperm, and 

 embryo of the economic genera Vicia and Ervum. The pre- 

 vious autumn, Junowicz (128), 1877, gave detailed accounts 

 of the Malpighian cells in several Leguminosae. Godfrin 

 ( 71 ), 1880, in his paper on the testa of angiosperms, described 

 Lupinus, Vicia, Orobus, and Ti'igonella. Harz (99), 1885, 

 in his extensive study of the seeds of economic plants, gives 

 accurate and detailed accounts of many leguminous seeds. 

 Tichomiroff (260), 1884, briefly notes the microscopic char- 

 acters of the seed of Abrus precatoriiis. Mention should 

 also be made of the work of Hanausek (91), 1884, and 

 Moeller (179), 1886, and other pharmacognostical writers who 

 have discussed the seeds of medicinal plants . Mattirolo (169),
