to show their first flowers, and were found in the sandy 

 moist bed of a deep ravine, out of reaoh of the sheep. The 

 remnants of a few of the parent shrubby plants were after- 

 wards discovered on the rocky summit above. 



Heuchera maxima. Caulescent, the stout, fleshy decum- 

 bent branches 1 — 2 feet long and nearly an inch thick, leafy 

 throughout: leaves round-cordate, 3 — 6 inches in diameter, 

 with 5 shallow lobes and large rounded, but abruptly slen- 

 der-pointed teeth: petioles and leafy peduncles stout, of 

 about equal length, hirsute : thyrsus narrow, 8 — '12 inches 

 long : calyx white, 3 lines long, acute at base : petals minute, 

 white. 



Rocky steeps near the sea, on the northward slope of 

 Santa Cruz Island. An enormous species of Heuchera, the 

 stout caudex-like stems more or less reclining, often fully 

 two feet long, and many of them from the same root; simple 

 or with suberect branches, all having numerous axillary, 

 leafy peduncles which are rather short, the thyrsus alone 

 rising higher than the leaves.

Having been favored with an opportimity of visiting the 

 island where this interesting tree is endemic, I wish to add 

 here a few remarks concerning it. The fruit, which in the 

 latter part of July was found nearly mature, is assuredly 

 that of a Saxifragaceous rather than a Rosaceous plant, con- 

 sisting as it does of a pair of follicles rather than a two- 

 celled capsule : and so the opinion of Professor Gray as to 

 the ordinal place for the genus is well confirmed. But the 

 flowers are altogether indistinguishable from those of the 

 Rosaceous genera Vauquelinia and Heteromeles. The tree 

 is no rarity on its native shore. There are a hundred 

 fine groves of it distributed up and down the thirty miles of 

 the island's northward slope, individual specimens often as 

 high as thirty-five and forty feet. The wood, close-grained
