The herbarium of the California Academy of Sciences now numbers 

 50,559 specimens all mounted and classified according to the latest system. 

 It includes both Phanerogams and Cryptogams. Altogether there are 

 3116 genera and 17,112 species. 



The Cryptogams are not so well represented as the Phanerogams, but 

 there are some notable collections. Among -the Lichens is the Hasse col- 

 lection which has been purchased by the Academy. It furnished the ma- 

 terial for "Contributions from' the U. S. National Herbarium, Vol. 17, 

 part 1, The Lichen Flora of Southern California by Hermann Edward 

 Hasse". The total collection of lichens contains 89 genera, 320 species, and 

 394 specimens. The collection of mosses contains 140 genera, 298 species, 

 and 674 specimens most of which were donated by Dr. C. Hart Merriam. 

 The collection of hepatics contains 13 genera, 21 species, and 40 specimens. 



The collection of fungi is the most valuable of the Cryptogams since it 

 consists of the 474 types from the Harkness collection which were saved 

 from the great fire. A few have been added from time to time by the 

 curator, but are at present unlisted as the determinations are uncertain. 



Besides these types of California fungi, there are 1855 Phanerogams, 

 most of which were also saved from the fire, and eleven Galapagos types 

 and cotypes of Allocarya recently determined by C. V. Piper. This material 

 was loaned to the National Herbarium and the results of Mr. Piper's 

 studies will soon appear in one of the contributions from the National 

 Herbarium. The Academy's herbarium contains also a number of new 

 species to be described soon, which will add to the accumulation of types. 



The additions to the herbarium have come in various ways ; 1005 speci- 

 mens were received in exchange, 807 came as gifts from 24 different donors, 

 most of them being specimens for identification. The curator added 1300 

 specimens and many duplicates. Besides the Hasse collection of lichens 

 the Academy purchased the valuable mounted collection of Idaho speci- 

 mens which formed the herbarium of John M. Holzinger. These plants 

 were collected in the region traversed by the Lewis & Clark Expedition 

 and the report on them was published by Professor Holzinger in Contri- 

 butions from the U. S. National Herbarium, Vol. Ill, No. 4. 



The southern California branch of the U. S. Forest Service presented 

 the Academy with its herbarium. This consisted of 149 mounted sheets, 

 chiefly specimens of Eucalyptus, representing almost as many species as 

 specimens; also 93 bottles containing seeds of 86 species of Eucalyptus. 

 This is a valuable addition to our herbarium and will be of great assist- 

 ance in identifying the numerous species of this difficult genus so widely 

 cultivated in California. 



The Botanical Club numbers sixty-five members and holds weekly 

 meetings. These are chiefly field trips, some in Golden Gate Park to study 

 the exotics and others in the San Francisco Bay region, where cultivation
