TRACHELOSPERMUM

below the middle; several jagged scales at base of 

 corolla; 5 large glands at base of ovary, 2 united, 3 free. 

 S. China. B.M. 4737. Gng. 5:132. Gn. 41, p. 507. 

 J.F. 1:61. R.H. 1902, p. 367. G. 37:191. Var. varie- 

 gatum, Hort., has Ivs. of green and white, tinged red. 



T. divaric&tum, Kanitz (T. crocostomum, Stapf). Similar to T. 

 jasminoides in habit, but differs in having slightly smaller buff or 

 pale orange-colored fls. with exserted stamens, pointed in bud, and 

 smaller Ivs. Japan, Korea. G.W. 12, p. 415. It is more hardy 

 than T. jasminoides. WlLHELM MlLLEE. 



TRACHYCARPUS (Greek, rough or harsh 

 and fruit). Palmdcese, tribe Coryphese. In- 

 door and outdoor palms, one of which is 

 widely grown and very hardy. 



Tall unarmed palms: Ivs. suborbicular or 

 reniform, folded, many-cut; segms. narrow; 

 rachis none: spadices many between the Ivs., stout, 

 branched; spathes many, sheathing, coriaceous, tomen- 

 tose, compressed; bracts minute: fls. small, polygamo- 

 moncecious; sepals 3, ovate; petals 3, broadly ovate, 

 valvate; stamens 6; carpels 3: drupes 1-3, globose or 

 oblong. About 4 species, Himalayas, China, and 

 Japan. Monographed by Beccari in Webbia 1:41-72 

 (1905). 



Fortune's palm (T. excelsa or T. Fortune?) is grown 

 both indoors and out in America wherever palms are 

 grown, although it is not one of the most popular spe- 

 cies with northern florists. It is grown throughout 

 California and even as far north as Oregon. It is com- 

 monly known by the name of Chinese windmill palm 

 in southern California. There are two types of trachy- 

 carpus, those which have the trunks covered with old 

 leaf-sheaths the Himalayan type and those which 

 have smooth polished trunks the far-eastern species. 



excelsa, H. Wendl. (T. Fortunei, H. Wendl. Chamse- 

 rops excelsa, Thunb. C. Fortunei, Hook. f.). FOR- 

 TUNE'S PALM. Fig. 3827. Trunk robust, clothed with 

 old If .-sheaths: Ivs. nearly orbicular; segms. numerous, 

 ensiform: fls. clustered 2-4 on a tubercle: fr. transversely 



e'obose-reniform, deeply umbilicate. Upper Burma, 

 hina, and Japan; will grow in the open in Ga., with- 

 standing 10 F. This description follows Beccari, who 

 refers T. Fortunei to T. excelsa. Hooker in founding 

 T. Fortunei (B.M. 5221) speaks of it as a more robust 

 tree than T. excelsa. The latter (which is from Japan) 

 is said to have smaller and stiffer Ivs., less deeply 

 divided (usually only about to middle) with stiff segms., 

 while T. Fortunei (China) has Ivs. divided much below 

 the middle (as in Fig. 3827), and the segms. more flac- 

 cid at least in older Ivs. This group needs further 

 study botanically, and also horticulturally in this 

 country. 



Martiana, H. Wendl. (T. Khasidna, H. Wendl. 

 Chamasrops Martiana, Wall.). Trunk slender, tall, 

 annulate-scarred, for the most part naked: Ivs. nearly 

 orbicular, divided to the middle into numerous segms.: 

 female fls. solitary, sessile: fr. oblong-elliptic, rather 

 compressed, rounded at both ends; seeds deeply sul- 

 cate. Himalaya region, Khasia, Burma, and Assam. 



nana, Becc. Subacaulescent: Ivs. deeply many- 

 parted, glaucescent beneath; segms. shortly bidentate 

 at the obtuse apex: female fls. globose-ovate: fr. reni- 

 form, umbilicate and superficially sulcate. China. 

 Takil, Becc. Trunk robust, strongly clothed with 

 old If .-sheaths: Ivs. persist- 

 ent, nearly orbicular; segms. 

 numerous, ensiform, shortly 

 bifid or deeply and irregularly 

 2-parted: female fls. clustered 

 2-4 together: fr. transversely 

 reniform, deeply umbilicate. 

 Himalayas.

3827. Trachycarpus excelsa. The leaves finally become 4 to 5 

 feet across. 



3828. Trachymene caemlea. 



TRACHYLOBIUM (Greek, 

 rough and pod; the upper sur- 

 face of the pod is tuber- _ 

 culate - roughened ) . Leguminosse. 

 Unarmed trees : Ivs. with 2 If ts. which 

 are coriaceous; stipules caducous: 

 fls. white, panicled at the ends of 

 the branches; calyx-tube disk-bear- 

 ing, narrow - turbinate, segms. 4; 

 petals 5, sometimes the 3 upper 

 clawed and suborbicular, the 2 lower minutely scale- 

 like, sometimes all subequal and clawed; stamens 10, 

 free; ovary short-stipitate : pod ovoid-oblong, thick- 

 coriaceous, warty-rugose, indehiscent. Three species, 

 Trop. Afr., Mascarene Isls., and Trop. Asia. T. verru- 

 cosum, Oliver (T. Hornemannianum, Hayne). Tree 

 wholly glabrous excepting the tawny or silky pubes- 

 cent infl.: Ifts. 1-paired, obliquely oblong or elliptical, 

 acuminate or apiculate: panicles overtopping the Ivs.; 

 calyx-segms. obovate-eliiptical or oblong; petals pos- 

 terior and lateral subequal, anterior equal or rudimen- 

 tary: pod 1-2-seeded, oblong or obovoid, 1M~2 in. 

 long. Mozambique and Madagascar. Gt. 51, p. 633. 

 T. verrucosum has the anterior petals nearly equal the 

 rest; T. Hornemannianum has them rudimentary.

TRACHYMENE (Greek, rough membrane, alluding 

 to the fr.). Umbelliferae. Hirsute or rarely glabrous 

 annual or perennial herbs, used as garden annuals: 

 Ivs. ternately dissected or rarely undivided; stipules 

 none: umbels simple: fls. white or blue; calyx-teeth 

 minute or obsolete, rarely 1-2, subulate; petals entire, 

 obtuse; disk flat: fr. laterally compressed, usually flat. 

 About 25 species, mostly Australian but a few from 

 Borneo, New Caledonia, and Celebes.
