﻿62 BOTANICAL GAZETTE [JANUARY 



account of the general ecological features and plant products of the island is 

 followed by an interesting " Botanical history," which gives a very full 

 account of botanical work on the island previous to the visit by the author 

 himself. The list is based on Baron Eggers's well-known Flora of St. Croix 

 and the Virgin Islands, 117 species being added. The total flora, as now 

 known, numbers 1,029 species, 992 of which are vascular plants. It is 

 pleasant to note that the author has succeeded in distributing his whole 

 collection under published species, with the single exception of a species of 

 Cordia. — J. M. C. 



The first part of Sargent's Trees and Shrtibs^ h?is appeared. The 

 general scope of the work may be obtained from the title and from the pre- 

 liminary announcement made in Box. Gaz. 34: 388. 1902. Those 

 acquainted with the Silva of Professor Sargent will recognize the same 

 general style and arrangement of text and plates, the latter being reproduc- 

 tions of original drawings made by C. E. Faxon, probably the most skilful 

 and experienced botanical draftsman in America. This first part contains 

 descriptions and illustrations oi Juglans mexicafta S. Wats., seven new species 

 of Crataegus (C durobrivensis Sarg., C. Laneyi Sarg., C. Coleae Sarg., C. 

 maloides Sarg., C luculenta Sarg., C, fruttcosa Sarg., C, paludosa Sarg.), 

 Etipatorium Loesenerii Robinson, Senecio Robinsontantts Greenm., Styrax 

 Rmnirezii Greenm,, Faxo?ia7ithus Pringlei Greenm. (a new Mexican genus, 

 singularly described with no statement as to its family), Ehretia viscosa 

 F erndildy Berberis Sieboldi Miq., Ilex serrata Thumb., Acer capillipes Maxim., 

 A, Tschonoskii M?iX\m., Malus Halliana Koehne, Viburnum Wrzghtii ^l"^^*^ 

 four new species of Lonicera (Z. saccata Rehd., Z. Koehneana Rehd., L. 

 ferruginea Rehd., Z. arizonica Rehd.), Z. Griffithii Hook, f. and Thorns,, 

 Enkianihus subsessilis Makino. — J. M. C. 



NOTES FOR STUDENTS. 



Massart has published a preliminary work ^° on the influence of polli- 

 nation on the growth of the fruit of Cucurbitaceae. He finds that the initial 

 stimulus to growth is from the pollen, and is perceptible when killed pollen is 

 applied to the stigma. The further growth of the fruit is dependent on a 

 stimulus from the "fertilized ovules," whose transmission is limited, so that 

 cavities are formed when no embryos are formed in some chambers of the 

 fruit. — E.B. COPELAND.
