1. R. Lyallii, Hook, f., Handbk. N.Z. Fl. 4. Rootstock very stout. 

 Stem 1ft.— 3ft. high or more, paniculately branched. Radical leaves on long 

 stout petioles, peltate, orbicular, slightly funnel-shaped, coriaceous, crenate, gla- 

 brous or with few scattered hairs, 6in.— 15in. in diameter. Cauline leaves few, 

 sessile, lobed, connate. Peduncles 'stout, with linear bracts, villous. Flowers 

 numerous, white or cream-coloured, 2in.— Sin. in diameter. Sepals 5, pilose. 

 Petals 5—10 or more, broadly cuneate, with a narrow gland at the base. 

 Anthers oblong, on short filaments. Receptacle cylindrical, hairy, elongating 

 after flowering. Achenes villous ; style subulate, flexuous. 



SOUTH Island : Spencer Mountains to Otago. STEWART Island : Mount Anglem. 2,000ft. 

 to .5,000ft. Shepherd's lily. Nov. to Jan. 



The leaves of seedling plants vary in shape from ouneate-rhomboid to reniform, but are not 

 peltate. The noblest species of the genus. 



2. R. Traversii, Hook.f., Handbk. 4. Similar to R. Lyallii, but smaller. 

 Leaves 4in.— 7in. in diameter, margins crenate or doubly crenate or lobed, and with 

 one or two deep incisions at the base forming a closed sinus. Carpels not seen. 



SOUTH Island: Canterbury: Hurunui Mountains. Otago: Mount Earnslaw. 

 This appears to be a variety of the preceding; but I do not care to unite the two until 

 the carpels have been examined. 



3. R. insignis, Hook. /., Fl. N.Z. i. 8, t. 2. An erect robust panicu- 

 late species, lft.-2ft. high, villous in all its parts ; brown or reddish-brown 

 when dry. Radical leaves on stout sheathing petioles, rounded-ovate or 

 cordate, rarely reniform, very coriaceous, crenate or lobed, 4in.— 6in. broad. 

 Panicle much branched ; peduncles numerous, bracts linear, oblong. Flowers
