them and the Tasrnanian and S. American species, which all have serrated 

 leaves. The growth, hahit and general appearance of this species (F. 

 apiculata), with its thin and scattered leaves and flattened spreading 

 branches, is very much like that of the northern variety of F. fusca, from 

 Tvaitaia near the North Cape, which I have ever supposed to be distinct 

 from the Fagus of the East Coast (Poverty Bay), as well as from the 

 plant of Whangarei (Bream Bay) ; * though at present those three (vars. ?) 

 are all classed under F. fusca. I have never, however, seen the northern- 

 most plant in flower or fruit. 



Class II. Monocotyledons. 

 Order I. OBCHIDEiE. 

 Genus 3. Bolbophylhim, Thouars. 

 Bolbophyllum tuberculatum, sp. nov. 



Plant epiphytal, forming irregular patches on upper forks of large trees 

 (Dacrydium cupressinum) ; roots 2-3 inches long, stout ; leaves linear-oblong, 

 8 lines long, 2 lines broad, acute, sub-apiculate, entire, glabrous, dark-green 

 on upper surface, of a lighter-green below, and there minutely and closely 

 dotted with round greyish dots, flat or slightly involute, thickish but not 

 fleshy, having 8-10 parallel veins which are transversely netted, keeled ; 

 stipe- stoutish, 1 line long; bulbs ovoid, 3-3^ lines long, turgid, ridged; 

 ovary oblong, 2 lines long, glabrous, greenish- white, tuberculated in rows, 

 tubercles blunt, reddish ; scape 6-8 lines long, springing from rhizome 

 below base of bulb, slender, turgid and sub-pyriform at base, reddish, muri- 

 cated, bearing a short raceme of 2-3 flowers ; flowers alternate, rather dis- 

 tant on short pedicels, -J- line long, each having a bract at its base ; bracts 

 sessile rather more than half-clasping, deltoid- acuminate with a produced 

 stout obtuse tip. 



Hab. In forests near Petane, Hawke's Bay, 1883 : Mr. A. Hamilton. 



Obs. — A species very distinct from our long known and common B. 

 pygmaum, Lindl. ; apparently rare, though possibly confounded with that 

 species. It is a much larger plant of similar appearance and habit. I 

 regret that I have not yet seen new and perfect flowers. 

 Genus 9. Corysanthes, Brown. 

 Corysanthes hypogcea, sp. nov. 



Plant very small, terrestrial, tender, succulent ; leaf single, 5-8 lines 

 diameter, membranous, shining, much veined, veins largely anastomosing 

 with longitudinal dots in the interspaces, corclate-reniform, 3-lobed at tip, 

 middle lobe produced, acute acuminate, side margins sinuate with a single 

 notch on both sides near base, auricles large, distant, subhastate, very 

 blunt ; light green above, midrib and marginal spots purple ; silvery below
