BORRAGINACE.E. 423 



O. nana, Gray, 1. c. Eritrichium nanum, Schrad., &c, p. 190, with its varieties. To syn. 

 add : Hook. f. Bot. Mag. t. 5853, which well exhibits the oblique position of the forming 

 nutlets. 



O. Howardi, Gray, 1. c. Depressed-caespitose, silky-canescent and silvery : leaves linear- 

 spatulate in the dense tufts, linear on the few -flowered sparsely bracteate (barely span high) 

 flowering stems, half-inch or more long : calyx-lobes linear-lanceolate : corolla bright blue, 

 4 or 5 lines in diameter : nutlets very smooth, obliquely truncate on the back, wingless, but 

 the margin of the ovate acutish and flat or slightly depressed dorsal disk with a sharp mar- 

 gin, and its face either smooth or minutely papillose and puberulent. — Cynoglossum How- 

 ardi, Gray, p. 188. — Bocky Mountains in Montana, Winsloiv J. Howard, about 1866. 

 Montana, on Mount St. Helena, Canby, 1883, -with fruit ! Cascade Mountains, Washington 

 Terr., Tweedy, 1882. 

 O. aliesa and O. cardiophylla, Gray, are Northern Mexican representatives, with a 



difference, of the typical Omphalodes. 



II 1 . KRYNlTZKIA, Fisch. & Meyer, extended. (Prof. J. Krynitzki, 

 of Cracow.) — Chiefly North American herbs, annuals and some perennials ; 

 with small white flowers, an anomalous species yellow-flowered. — Fisch. & 

 Meyer, Ind. Sem. Hort. Petrop. vii. 52 (1841) ; Gray, Proc. Am. Acad. xx. 

 264. Krynitzhia & Eritrichium, sect. 5-7, A. DC. Prodr. x. 128, 134. Eri- 

 trichium § Krynitzhia, & § Eueritrichium Myosotidea, & Antiphytum, Gray, Proc. 

 Am. Acad. x. 55, & Syn.'Fl. ed. 1, 191-197, 199. 



§ 1. Ambltnotus, Gray, Proc. Am. Acad. xx. 264. Nutlets cartilaginous or 

 crustaceous (almost as in Lithospermum), ovate, with rounded back (mostly not 

 carinate), attached next the base to the low and convex or depressed pyramidal 

 gynobase. 



K. Parryi, Gray, 1. c, is doubtless North Mexican rather than a Texan species. 

 K. heliotropioid.es, Gray, 1. <z. 265, is Antiphytum heliotropioides, A.DC, & p. 199. 

 EL. floribunda, Gray, 1. c, is A. floribundum, p. 199. 



TC . litliooarya, Greene. Low and slender annual, resembling species of the following 

 section, somewhat pubescent : leaves linear : racemes or spike simple, sparsely-flowered, 

 partly bracteate : corolla white, not surpassing the ferruginous-pubescent calyx : nutlets 

 turgid-ovate, rather over a line long, very smooth and shining, lightly carinate down the 

 rounded back and sulcate down the ventral side, attached by a short line or grooved scar 

 from the base up a quarter of the length. — Gray, Proc. Am. Acad. xx. 265. — Lakeport, 

 Lake Co., California, Mrs. Layne- Curran. Anomalous species, perhaps to be placed in the 

 vicinity of K. leiocarpa. 



§ 2. Myosotidea, Gray, 1. c. Nutlets less indurated, ovate, opaque, coarsely 

 somewhat rugose, ventrally carinate, with short and merely intrabasal attach- 

 ment to a low gynobase : low and slender Western species. — Eritrichium § Eu- 

 eritrichium Myosotidea, p. 191. 



# Small-flowered annuals, diffuse, with corolla only a line or two broad and little surpassing the 

 calyx, which usually becomes foliose-ampliate. 



K. pleb6ia, Gray, 1. c. 266, is Eritrichium plebeium, A.DC, p. 191. 



TC . Californica, Gray, 1. c, is E. Californicum, DC, p. 191. The var. subglochidiata 

 includes most of the interior forms of the species, but is also in the valley of California, 

 where also it becomes succulent in alkaline soil. The little bristles of the fruit are com- 

 monly penicillate-tipped, sometimes truly glochidiate, thus making a kind of transition to 

 Echinoglochin of Echinospermum. 



K. traohyoarpa, Gray, 1. c. Less spreading than the preceding, lax : nutlets broadly 

 ovate-trigonous, acute, finely reticulate-rugose and granulate or muriculate : scar oblong. —
