LV. Plantae novae Texanae 
a B. F. Bush descriptae. 
(Ex: Missouri Bot. Gard. Rep., XVII [1906], pp. 119—125.) 
1. Tracyanthus angustifolius var. Texanus B. F. Bush, |. c., p. 119. 
Foliage glaucous. Stems 7—15 dm tall, simple, with compound 
racemes at the top. Leaf-blades narrowly linear, 2—6 dm long, shorter 
above, flat; racemes ovate in outline, compound, 10—20 cm long; pedicels 
slender, 1—2 cm long; perianth decidedly yellowish; sepals and petals 
oblong, narrowed at the base, the sepals somewhat broader, all 4—5 mm 
long, acutish at the apex; capsules not seen. 
Sandy swamps, eastern Texas. Spring. 
Differs very greatly in appearance from T. angustifolius (Michx.) Small, 
in the large compound panicles, the more robust size, and in the deci- 
dedly yellowish flowers. 
Specimens examined: Texas: The only specimens seen are those of 
the type, collected at Swan, Smith County, by J. Reverchon 2782, 
May 16, 1902. 
2. Allium hyacinthoides B. F. Bush, l. c., p. 119. 
Bulbs usually several together in bunches, 2—3 cm high, their coats 
prominently fibrous-reticulated. Scapes terete, 2—3 dm tall; leaves basal, 
channeled, 3—4,5 mm wide, much shorter than the scape; bracts of the 
umbel 3, ovate, acuminate; umbel erect, many-flowered, rarely bulblet- 
bearing; pedicels filiform, 12—15 mm long; flowers pink, very swet- 
scented, 6—9 mm long; perianth segments oblong, obtuse, thin, with a 
reddish midvein, twice longer than the stamens; filaments but little 
dilated below; capsule 3—3,5 mm high, 4—4,5 mm wide, its valves not 
crested. 
Calcareous limestone prairies, central Texas. Early spring. 
A. hyacinthoides is quite readily distinguished in the field by its very 
fragrant attractive pink flowers, very early blooming, and habit of growing 
in bunches. From 4. mutabile Michx., to which it is related, and with 
which it has been confused, it differs in being very fragrant, in having 
shorter stems, rather longer obtuse sepals which are twice longer than 
the stamens, smaller capsules, shorter pedicels, different habitat, and an 
earlier season of blooming. 4. mutabile Michx. grows in sandy woods 
about Dallas, Texas, and blooms from two to four weeks later. 
Specimens examined: Texas: Dallas, Bush 270, April 14, 1900; 
Reverchon 2183, April 5, 1900; Reverchon 4025, April 1, 1850. 
3. Psoralea subulata B. F. Bush, |. c., p. 120. 
Acaulescent or nearly so, 1,5—3 dm tall, from a shallow seated, oval, 
farinaceous bulb. Stems densely pubescent with long, shaggy white 
hairs, many-leaved and many-flowered. Petioles 1—2 dm long, much
