S. CouUeri Brandegee. Proc. Cal. Acad. 2ud Ser. II. 135. 



One of the most common plants of Lower Caiifornin. Dr. Palmer found it in 

 the ravines and sandy spots contiguous to the beach at La Paz, growiuj^2 toJi 

 feet high. Mr. Brandegee writes me that in moist jdaces it is lU to 12 feet high. 

 It is a rough, homely plant, avoided by all grazing animals. In habit and pubes- 

 cence the plant resembles Xantus's (No. 10) plant from Cape St. Lucas, but the 

 carpels are entirely different, in fact they arc almost the exact counterpart of 

 those of S, CouUeri Gr. This strong similarity has led Mr. Brandegee into the 

 err()rol' referring his sjiecimens of last ye:ir to this species. While the carpels 

 are so similar and like no other Spluvralcea, still there seems a slight diflfereuce. 

 S. CouUeri Gr. is less pubescent and the terminal part (wrongly called the 

 "horizontal projection at base" by Watson and Brandegee) is very broad and 

 obtuse, iS. CitUformca is said by Mr. Brandegee to be an annual, but appears 

 to be biennial or perhaps perennial. S. CouUeri Gr., originally described as per- 

 ennial, is clearly an annual. It is also very ditf'ereut in habit; S. CouUtriGr., 

 is either procumbent or with branches ascending, while tS. CaUfornica is tall and 

 erect. Tlie pubescence is very different as well as the shape and tootliing of 

 the leaves, and the size and color of the llowers. No. 18, 



Horsfordia Palmeri Watson. Proc. Ann r. Aca<l. XXIV. 40. Six feet high, with 

 single upright stem and many lateral branches: lower leave84to5 inches long.

 female diseases. No. 96. 



Horsfordia rotundifolia Watson. Proc. Amer. Acad. XXIV. 41. Found sparingly 

 on a stony ridge. No. 117. 



Sida Xanti Gray. Proc. Amer. Acad. XXII. 2m. Collected by Xantus 1859-'60, but 

 not described until three years ago. The flowers are described as " apparently 

 white but perhaps yellow." Dr. Palmer spiaks of the " golden-colored bloom," 

 but in the plants before ns there is a ])urplish tinge. The few jdants obtained 

 are from a stony ridge. It grows :5 to 4 leet high, with two or three slender 

 stems from the base and few lateral branches. No. 27. 



Abutilon Palmeri Gray. No. 90. 



Abutilon incanum Don. A plant 3 or 4 feet high, growing in sandy gulches among 

 shrubs. No. 120. 



STERCULIACE-S3. 



Hermannia Pa'meri Rose n. sp. Stems perennial, weak, the long slender branches 

 supported by other plants, densely stellate-pubescent : leavesdeltoid in outline, 

 cordate at base, b to 12 lines long, dentate, on petioles 4 to 8 lines long; ped- 

 uncles slender, 6 to 15 lines long, I to 2-llowered, articulated at the upper bract, 

 becoming redexed : calyx 3 to 4 lines long, deeply cleft into lanceolate acute 

 lobes, not enlarged in fruit: corolla golden yellow; petals 4 to 5 lines long, 

 orbicular, cuneate at base, with an abrupt tip, spreading or reflexed: stamens 

 5; filaments very short ; anthers erect, free but conntvent as in Solanum i styles 

 cohering : capsule C lines long, oblong, the dorsal crest of each capsule armed 

 with long glochidiate spines ; seeds 5 to 7 in each cell, somewhat incurved, the 

 hilum end somewhat pointed, the surface dull with irregular depressions. 

 Grows under shade of bushes on sandy mesas. Also collected at Todos Santos 

 by Mr. T. S. Brandegee. No. 29. 



Melochia tomentosa L. An upright growing shrubby plant, about 6 feet high, on
