24 PLANTS WRIGHTIAN^. 



BYTTNERIACE^. 



66. Melochia pyramid ATA, Lin7i. ; Gray, Gen. III. 2. t. 134, ^ PI. Lindh. 2. p. 

 165. Western Texas, in wet places. 



67. Hermannia Texana, Gray, Gen. HI. 2. p. 88. t. 135. On the Sabina and 

 Rio Grande, Western Texas. — I have already remarked, in Plantce Lindheimeri- 

 ance, 2. p. 165, that the corolla is wrongly represented as expanded in the figure 

 above cited of this interesting plant ; the drawing having been made from a dried 

 specimen. 



(644.) Ayenia pusilla, Linn.; Cav. Diss. 5. p. 289. t. 147; DC. Prodr. 1. p. 

 488 : var. tenuiter pubescens ; ramorum assurgentium foliis ovato-lanceolatis subcor- 

 datis acutatis. — Hill-sides from the San Pedro River to near the Rio Grande, New 

 Mexico ; July, Aug. — The seeds are coarsely rugose-corrugated, as in the West 

 Indian A. pusilla ; of which Mr. Rugel has gathered a small-leaved form at Key 

 West. 



(645.) A. PUSILLA, var. ramis erectis, foliis superioribus lanceolatis ; C8et. prseced. 

 — Hills at the head of the San Felipe, Western Texas, July. Also in the collec- 

 tion of 1851. It has a thick, manifestly perennial root. — This and the preceding 

 have so much the aspect of a Tragia as to have been passed as such in the dis- 

 tribution. 



(77.) A. MiCROPHYLLA (sp. uov.) : fruticosa, humilis ; caulibus ramosissimis ; foliis 

 parvis ovato-rotundis grosse dentatis pube stellata brevissima fructibusque cinereis 

 in ramulos confertis; stipulis subulatis persistentibus ; capsula non stipitata. — 

 Mountain-sides, near El Paso ; Sept. — Stems a span high, woody and rigid, as are 

 also the spreading branches ; the growth of the preceding year more or less squai-- 

 rose with the short and the subulate persistent stipules. Leaves only 2 or 3 lines 

 long, roundish, obtuse, coarsely toothed, often subcordate, marked with a few strong, 

 straight veins, on short petioles. Fruit nearly a quarter of an inch in diameter, on 

 a peduncle of less than that length, and not at all stipitate, 5-coccous, cinereous- 

 pubescent, and verrucose-echinate with soft processes. Seed solitary in each cell, 

 oblong. — Unfortunately, I find not a single fl.ower upon the scanty specimens, and 

 only a few capsules ; but I doubt not it is an Ayenia, and a very distinct one. 



TILIACE^. 



68. CoRCHORus piLOLOBus, Link, Enum. hort. Berol. 2. p. 72; DC. Prodr. 1. 

 p. 504, ex Shuttleworth in sched. PI. Rugel. et. litt. C. septentrionalis, Planchon in 

 herb. Hook. C. siliquosus, Torr. 8r Gray, Fl. 1. p. 239; Gray, Gen. III. 2. t. 127, 

 non Linn. Along streams, San Pedro River, &c. ; Aug. Also on the Rio Grande, 

 Texas. — This is perfectly distinguished from the West Indian C. siliquosus, Linn., 

 as pointed out by Mr. Shuttleworth, by the proportionally shorter pods, conspicuoiis- 

 ly acuminated by the undivided style (not obtuse and two-toothed at the apex). 

 Link's name is not an appropriate one, as the pods are only minutely and inconspic- 

 iiously hairy or pubescent. The true C. siliquosus has also been found in Key 

 West, by Mr. Blodgett and Mr. Rugel.
