DESCRIPTIONS IN GRAY’S PLANTZ WRIGHTIANA. 517 
0. 85), often only two or three inches high, but much branched, with manifest stipular glands ; the capsule ovate 
an acute. It appears very near to L. Frisians var.] puberulum ; but the structure of the false dissepiments is decisive. 
§ 2. Capsules 10-valved. 
* Styles united at the base or below the middle. 
6. L. Boorti, Planchon, Annual; styles in northern (St. Louis) specimens united at or below the lower 
third only, in Texan specimens (8. Planchon) almost to the middle ; capsules globose, acute, 10-valved ; the secondary 
dissepiments incomplete, with numerous hair-like fibres on the margin. — No. 86, Pl. Fendl. belongs here, and not to 
L. rigidum. This is the only one of our species with a 10-valved capsule, where the styles are somewhat united. 
* « Styles free to the base. 
t Secondary dissepiments incomplete. 
7. L. RuPESTRE, Engelm. in Pl. Lindh. 2, p. 232. Capsule globose-ovate, acute or cuspidate, like that of the 
foregoing species, but smaller ; secondary dissepiments exactly the same ; distinguished principally by the perennial 
ligneous root, the subulate leaves, the smaller flowers and fruit, and the entirely free styles. — Found by Lindheimer 
about New Braunfels and Comanche Spring; by Wright (No. 71) on Turkey Creek. Dr. Gregg collected it near 
Saltillo in June, and a variety, which may be named 8. cymulosum, on the battle-field of Buena Vista in May; this 
latter may be distinguished by the small and crowded cymes at the end of the branches. 
REGGII, n. sp. : viride, glabrum, caulibus pluribus e rhizomate ligneo adscendentibus a basi fruticulosa 
ramosis angulatis ; foliis alternis ‘i Gobbi oblanceolatis superioribus lanceolatis patulis ; glandulis stipularibus 
geminis rarius inconspicuis; cymis virgatis dissitifloris contractis; pedicellis calyce seepius longioribus ; sepalis 
lanceolatis acutis trinerviis margine glandulosis ; filamentis basi see dilatatis 2-denticulatis ; stylis liberis ; stig- 
matibus coherentibus ; capsula depresso-globosa cuspidata calycem subequante 10-valvi, dissepimentis secundastie 
incompletis. — Near Saltillo, Sept. Ist, 1848, Dr. Gregg, No. 387. — Stems about 10 inches high. Leaves similar to 
those of LZ. Virginianum, the capsule and seeds of the same size. Distinguished from L. rupestre by the broader 
leaves, much smaller flowers and fruit, the singular united stigmata, which I have found in all the flowers (and many 
of them) examined by me, and the hairless false dissepiments. Apparently near L. Mexicanum, but that species has 
opposite leaves, &c. 
+ + Secondary dissepiments complete and similar to the primary ones: capsule splitting into 10 closed cocci. 
9. Linum Viraerntanoum, Linn. Biennial (or perennial?) with a fibrous root (all the others have a tapering 
simple root). 
Var. 8. OPPOSITIFOLIUM : caule erecto ; foliis plurimis oppositis obovatis seu oblongis obtusis; panicula patula; 
sepalis integerrimis late ovatis acutis; petalis flavis. — Little Rock, Arkansas, in springy morasses with Sphagnum.

NGUSTIFOLIUM : caule stricto ; foliis erectis; panicula contracta sparsiflora ; sepalis lanceolatis capsulam 
pintanaig interioribus glandu ulosis; petalis sulphureis.— Western Arkansas, on sandy in open w 
Flowers and fruit larger than in the common form.

pilosulis ; floribus dioicis amentaceis precocibns basi tribracteolatis; petalis ciliatis; drupa pores subeompressa glan- 
dulari-pilosa, putamine levi. — Margins of thickets, on the top of hills, in the large prairie between New Braunfels 
and San Antonio, 15 miles = the former place, 1850; also gathered, without developed flowers, in 1846. It blos- 
soms in March, and shows ripe fruit in May. A large shrub; stems one or two inches in diameter, branching above, 
with numerous small branchlets. Leaflets 3 or 4 fines long. Disk 5-lobed, the lobes emarginate. true Lobadium
