tube of the calyTC obconic (very short), many times shorter than the linear 

 ovary ; petals (" ochroleucous," Nuit., about 2 lines long) broadly oval, en- 

 tire, rather acute, twice the length of the longer stamens and the style ; stigma 

 capitate, somewhat 4-lobed ; capsules erect, nearly straight; linear, slightly 

 quadrangular, scarcely attenuate at either end, on a short but distinct 

 pedicel. 



St. Diego, California, Nuttall ! May. — Plant a foot or more high, with 

 the habit of an Epilobium, very minutely puberulent. Leaves scattered, 

 about half an inch long and 1-2 lines wide. Tube of the calyx minute. 

 Anthers oblong, attached near the base ; those of the shorter stamens smaller. 

 Capsules an inch long and about half a line in diameter, cylindrical, but 

 slightly angled. 



61. CE. strigulosa : pubescent with minute hairs, at length nearly glabrous ; 

 stem slender, branched near the base ; leaves linear, denticulate, attenuate 

 towards the base ; flowers (very small) axillary ; tube of the calyx obconic, 

 very short, about half the length of the oblong-lanceolate (reddish) segments; 

 ovary filiform ; petals (a line long) broadly obovate, entire, exceeding (by 

 one-third) the longer stamens and the large stigma ; capsules elongated and 

 very slender, slightly quadrangular, torulose, sessile, of nearly the same 

 diameter throughout, at length incurved or somewhat contorted. — QL. siliquo- 

 sa, Nutt. ! mss. Sphaerostigma strigulosa, Fisch. Sf Meyer, ind. sem. St. 

 Petersb. (1833) p. 50. (ex descr.) 



Near St. Diego, California, Nuttall! (California, Fisch. Sf Meyer.) Also 

 in the Rocky Mountain plains near Lewis's River, Nuttall! — Stem 8-12 

 inches high. Leaves scarcely an inch long, less than a line -wide. Capsules 

 an inch long, scarcely half a line wide. Seeds oblong, terete. — The plant, 

 as Mr. Nuttall remarks, has wholly the appearance of a small Epilobium. 



62. CE. Andina (Nutt. ! mss.) : " very small, depressed, canescently 

 puberulent ; leaves linear-spatulate, attenuate into slender petioles, entire, 

 obtuse ; flowers minute, axillary, very nuinerous ; tube of the calyx infun- 

 dibuliform, rather shorter than the segments, many times shorter than the 

 subulate ovary ; petals (less than half a line long) obovate, entire, scarcely 

 exceeding the longer stamens, shorter than the st34e ; stigma large ; capsules 

 canescent, somewhat 4-sided, attenuate-subulate above, straight. 



" Dry plains in the Rocky Mountains, near the Black-Foot River. — A 

 very remarkable and distinct species. Stem about an inch and a half high, 

 sending off decumbent branches from the base. Leaves less than a line 

 wide, half an inch or more in length. Flowers commencing with the lowest 

 leaves. Capsules large for the size of the plant, 3-4 lines long : the dissepi- 

 ments almost wanting. Seeds cylindrical, on a filiform placenta." Nutt. 



(E. media (Link. enum. Bcrol.) appears from the description to be CE. linearis, 

 except that the capsules are said to be sessile. 



(E. (etragona (Roth) is doubtless CE. fruticosa.

Tube of the calyx not at all produced beyond the ovary ; the limb 4-parted, 

 reflexed. Petals 4. Stamens 8 ; the alternate ones (opposite the petals) 

 minute and mostly sterile : filaments filiform : anthers subglobose, fixed 

 above the middle ; those of the shorter stamens minute. Ovary oblong or
