 3 inches high, slender. Leaves 2 to 5 lines long and with petiole of 

 almost equal length. Peduncle and raceme filiform ; pedicels mostly 

 shorter than the calyx ; the latter in flower one line, in fruit two lines 

 long. Very short and small style deciduous from the capsule. Seeds 

 less than half a line long. 



HARPAGONELLA, Nov. Gen. Borraginacearum. 



Calyx inequalis obliquus, e sepalis 3 a basi solutis immutatis, 2 alte 

 connatis in cucullum fructiferum dorso glochidiatum auctis. Corolla

 globosa, gynobasi planiusculte affixa, duo abortiva ; ovula in fertilibus 

 erecta, anatropa, foramine infero. Nuculns 2, collaterals, lajves, ob- 

 longse vel subclavatte, ab areola parva adscendentes, una nuda sa?pe 

 infertilis, altera major intra cucullum calycinum 6-7-cornutum (corni-

•^ Harpagonella Palmeri. — Guadalupe Island, off Lower Califor- 

 nia, 1875, Dr. E. Palmer. A slender and sparingly branched annual, 

 2 to 5 inches high, cinereous-hirsute. Leaves linear, an inch or less 

 long, and the floral gradually reduced to bracts a line or two long. 

 Peduncles in fruit a line long, stout, and strongly recurved. Calyx in 

 flower barely a line long, 5-parted, except between two of the sepals, 

 v/hich coalesce to the middle ; below the sinus of the coalesceut divi- 

 sions is an external tufted appendage, which at length develops into 

 the soft-spiny horns. Short style slender to the base. Gynophore 

 not elevated. The two lobes of the ovary on the side of the flower 

 next to the three nearly separate and unclianged sepals (which we 

 may designate the lower side of the flower) are uniformly and early 

 abortive ; the other portion of the calyx accrescent, and soon gibbous- 

 involute into a sort of coriaceous burr, of about 2 lines m length, armed 

 with a few (usually 7) spiny horns, of a line or two in length, which 

 spread in all directions, and are beset for nearl}'^ their whole length
