THALICTRUM 



and northern varieties were found adapted, or profitable. 

 Some of these varieties that have originated in the 

 state are given in the following lists. 



T. V. MUNSON. 



SOME FRUITS THAT ORIGINATED IN TEXAS. 



Apples. 



herbs with large, long petioled, often canna-like leaves 

 and long scapes bearing large panicles of spikes of usu- 

 ally purple flowers. Fls. commonly 2 together in a 2- 

 valved spathe; calyx minute; corolla tubular, with 6 

 divisions, of which the 3 interior are unequal; style 

 thick, spiral; stigma 2-lipped, the lower lip long and 

 pendulous: capsule inflated, 1-loculed, 1-seeded. 



A. Plant covered with a white powder. 

 dealbata, Fras. Stemless: petioles 1-2 ft. long: Ivs. 

 canna-like, cordate, ovate, 6-9 in. long: scape terete, 

 3-5 ft. high: panicles erect: spikes erect. June-Sept. 

 Ponds and marshes, S. C. and west. B.M. 1690. B.B. 

 1:455. A fine and stately aquatic when well grown. It 

 should be placed in shallow water or in wet soil. 



AA. Plant not powdery. 



divaricata, Chapm. Stemless: petioles longer than 

 in T. dealbata: Ivs. banana-like, 1-3 ft. long, oblong- 

 ovate: scape 5-10 ft high: panicles 2-4 ft. wide: spikes 

 zigzag, pendulous. Sept., Oct. Ponds, Apalachicola, 

 Fla. According to Reasoner Bros., this magnificent 

 native ornamental-leaved marsh plant thrives in garden 

 soil with cannas and like plants. Does well under culti- 



vation in southern California. 



F. W. BARCLAY. 



THALfCTKITM (ultimately probably derived from 

 Greek tlinllo, to grow, but application doubtful), jRa- 

 nuncitlactus. MEADOW RUE. Erect perennial herbs: 

 Ivs. ternately compound and decompound ; stem-lvs. 

 alternate : fls. dioecious, polygamous, or perfect in 

 some species, rather small, generally greenish white 

 or sometimes purple or yellow, borne in a panicle or 

 loose raceme; sepals 4 or 5, deciduous; petals want- 

 ing; stamens many, showy: carpels usually few, 1- 

 seeded. This group includes several forms which are 

 well suited for the mixed border and rock garden. The 

 robust forms are desirable for the wild garden. Many 

 are very hardy, and only the more southern forms of 

 those given below are at all tender. Thalictrums are 

 valued for their feathery heads of flowers, contrasting 

 with their handsome stems and leaves, which are often 

 of a purple cast. They may be propagated by seed or 

 by division of roots in early spring, just as growth be- 

 gins. Any good loamy soil will suit them if well 

 drained. 



The latest monograph of the entire genus was pub- 

 lished in 1885, by Lecoyer, in Bull. Soc. Roy. de Bot. 

 de Beige, where he describes 69 species. In 1886 Wm. 

 Trelease published a fine treatment of "North American 

 Species of Thalictrum " in Proc. Soc. Bost. Nat. Hist. 

 23:293-304, in which he recognized 11 species and 4 

 varieties north of Mexico. His treatment is rather 

 closely followed by Robinson in Gray's Syn. Flora, 1895. 

 Since that time at least 10 new species have been de 

 scribed chiefly from Mexico several of which are by 

 J. N. Rose, in Cont. U. S. Natl. Herb. 5:185, Oct. 31, 

 1899. All North American forms were treated by the 

 present writer in Minn. Bot. Studies, Aug.. 1900. Be- 

 sides several native species, about 5 have been intro- 

 duced to our gardens from other countries. 



THALIA (J. Thalius, a German naturalist, and author 

 of Sylva Hercynia, a catalogue of the plants of the 

 Harz mountains'; died 1588). Scitaminacece. About 7 

 species of tender American perennial, stemless, marsh 



A. Fls. perfect. 



B. Filaments widened near the 

 anthers : anthers ovate, ob- 

 tuse. 

 c. Akenes sessile, in a head, 



ovate-oblong 1. petaloideum 



CO. Akenex xtolked, widely 

 spread iiit/, straight along 



dorsal margin 2. sparsiflorum 



BB. Filaments filiform : anthers 

 linear, acute or rnucronatc. 

 C. Fruits sulcate: stigma di- 

 lated on one side of the 

 short style 3. minus
