INDUSTRIAL PROGRESS DURING THE YEAR 1875. ccxix 



not to be taken into consideration in dividing the Thallo- 

 gens into classes. The Protophytes, as defined by Sachs, 

 constitute a group of which we know but very little, and 

 future studies may prove that it is not sufficiently well cha- 

 racterized. In the present state of our knowledge, however, 

 Sachs's group of Protophytes is as good as any. The class 

 of Oospore is a very natural one ; but the same can not be 

 said of the Carposporae, which, although in the main well 

 characterized, include plants whose position in that order is, 

 to say the least, doubtful. 



Attar of Roses. The Attar of Roses of commerce comes 

 almost entirely from Roumelia, on the southern side of the 

 Balkan Mountains. It is obtained from the flowers of Rosa 

 dcmiasccena, and, according to Mr. Baker, of Kew Gardens, 

 ranges from France to Asia Minor. 



Flora of Guadalupe. The island of Guadalupe, off the 

 coast of California, has recently been visited by Dr. Edward 

 Palmer, and a report on the Phaeuogamous plants and higher 

 cryptogams collected by him was made by Mr. Sereno Wat- 

 son, of Cambridge, to the American Academy of Arts and 

 Sciences, November 10th. The island is in latitude 29 

 north, about 220 miles from San Diego. It is only 25 miles 

 long by 10 broad, and its highest point is 3900 feet above 

 the level of the sea, yet the vegetation of the southern and 

 eastern portions of the island attains its perfection full two 

 months before that of the rest of the island. It has proba- 

 bly never been inhabited until within a few years, yet goats 

 have already begun to produce a disastrous effect upon the 

 native flora of the island. The number of species of higher 

 plants collected by Dr. Palmer was 133, distributed as fol- 

 lows : 102 exogens, 8 endogens, 21 vascular cryptogams, 

 and 2 undetermined plants. With regard to the flora, Mr. 

 Watson says : " Looking at the relative proportion which the 

 large orders bear to each other in this limited flora as com- 

 pared with the flora of Great Britain, which is the only simi- 

 lar one of which we have the data for comparison, we find 

 that the proportions which the Composite and Leguminosa3 

 bear to the whole are identical in both, 77 per cent. ; while 

 in the next largest orders, Cruciferae, Scrophulariacea3, and 

 Gramineaa, the proportions are very close. A marked dis- 

 crepancy is shown in the almost entire absence in Guada-
