STURTEVANT 



STYRAX 



1749 



30, 1898. Though holding the degree of M.D. from 

 the Harvard Medical School, Dr. Sturtevant never prac- 

 ticed the profession of medicine, but devoted his life to 

 agricultural work, first specializing on Ayrshire cattle, 

 then on pedigree corn (Waushakum) and muskmelons 

 (New Christiana), and afterward devoting particular 

 attention to the modifications which cultivated plants 

 have undergone as shown by such records as occur iu 

 the older books. In connection with these studies, Dr. 

 Sturtevant brought together a rare collection of books 

 dealing with plants published before the time of Lin- 

 nreus (say 1753), which, with his index cards and her- 

 barium, is now preserved at the Missouri Botanical 

 Garden in St. Louis, Mo. 



As first director of the New York Experiment Station, 

 at Geneva, Dr. Sturtevant drew the broad plans on 

 which the successful work of that establishment has 

 been conducted and which have served largely as mod- 

 els for subsequently organized agricultural stations 

 over the country. He was a man of active mind, and 

 his career is suggestive of worthy work to an unusual 

 •degree. A biographic sketch and a list of his principal 

 writings are printed in the Tenth Report of the Missouri 

 Botanical Garden. ^5,. Teelease. 



STYLO PHORUM (Greek, style and 

 bearing, in reference to the persistent 

 style). Papaveracew. A genus of prob- 

 ably 3 species of perennial herbs, one 

 American and the others from southeast- 

 ern Asia and Japan. Herbs with stout 

 rootstocks and yellow sap: lvs. lobed or 

 cut: fls. yellow or red, rather long- 

 stemmed, solitary or clustered ; sepals 

 2; petals 4; stamens numerous; placenta? 

 2-4 ; style distinct ; stigma 2-4-lobed,

 cent to the base.

 phorum, Hort. ). Celandine Poppy. 

 Fig. 2438. A hardy perennial about 1 ft. 

 high, forming large clumps: stem with 

 2 lvs. at the summit: lvs. light green, 

 pinnately parted : fls. yellow, 2 in.

STYRAX (ancient Greek name of Styrax officinalis). 

 Styracilcete. Storax. Ornamental deciduous or ever- 

 green trees or shrubs, with alternate, simple, serrate or 

 entire leaves and white often pendulous flowers in ax- 

 illary clusters or terminal racemes, followed by dru- 

 paceous dry or fleshy fruits. *S. Obassia, Americana 

 and Japonica are the hardiest and stand the winter in 

 sheltered positions as far north as Massachusetts; S. 

 grandifolia is hardy about Philadelphia and S. Cali- 

 fornica only south. The Storaxes are handsome shrubs 

 of graceful habit, usually loose and spreading. Their 

 flowers are numerous, white and mostly fragrant. They 

 are well adapted for borders of shrubberies or as single 

 specimens on the lawn, and thrive best in a light, 

 porous soil. Prop, by seeds sown soon after ripening 

 and by layers; sometimes grafted onHalesia tetraptera. 



About 60 species in the tropical, subtropical and 

 warmer temperate regions of America, Asia and Europe. 

 Trees or shrubs: lvs. short-stalked, exstipulate, more or 

 less covered, like the inflorescence, with stellate hairs: 

 fls. white; calyx campanulate, obscurely 5-toothed or 

 truncate; petals 5, connate only at the base; stamens 

 10, inserted at the base of the corolla and usually some- 

 what connate below: ovary superior, often united at the 

 base with the calyx, 3-loculed at the base, 1-loculed at the 

 apex; style slender: fr. a drupe, mostly subglobose, 

 fleshy oroftener dry with dehiscent pericarp, 1-2-seeded, 

 witn large, subglobose seeds. Styrax Benzoin yields 

 the benzoin, a balsamic exudation of the wounded tree; 

 storax, a similar gum-resin, was formerly obtained from 

 S, officinalis, but the storax of to-day is a product of 

 Liquidambar.
