[PLate 198. ] 
Native of Queensland. 
Epiphytal. Stems elongate, jointed, the joints three to four inches long, terete, 
cylindrical, many-furrowed. Leaves four to six, elliptic or oblong, thick coriaceous, 
deep green, nerveless. Peduncle stout, terminal, supporting a nodding raceme a 
foot long and upwards of four inches across. Flowers very numerous and densely 
packed, with a minute ovate bract at the base of each pedicel, which is one-and-a- 
half inch long, creamy white, with a very short ovary at top; dorsal sepals 
lanceolate from a broad base narrowing to the point, seven-eighths of an inch long; 
the lateral ones falcato-decurved acute, the base so expanded as to form a broad 
mentum or chin; petals rather shorter than the sepals, linear, drawn out into a 
subulate point; lip with a divergent claw, bearing a yellowish purple speckled bogs, 
then suddenly folded back (geniculate) so that the blade lies parallel with the 
column and petals, curved, oblong, with the sides erectly infolded, and marked with 
short transverse papillose lines of chocolate-purple, three-lobed, the front lobe reniform 
when laid out flat, striated mostly on the outer side, the side lobes oblong, curved, 
marked with lines as above noted, a single raised line forming a central blunt 
longitudinal ridge or crest, widening in the middle, yellow flushed with purple.

We have now to record one of our older Orchids, and one that is well known 
to growers generally, indeed, this Dendrobium Hill has been cultivated in many 
establishments where few other Orchids have been grown. It is a really noble 
plant, especially when well cultivated, as we have had the pleasure to witness when 
inspecting specimens with many spikes of its charming racemes proceeding from 
the strong growing pseudobulbs. We have seen the plants three feet across, and 
they may be managed without much trouble if they get the proper management. 
They require cool treatment, and may be grown in any conservatory or greenhouse. 
Our plate was prepared from a drawing taken from a well-grown specimen in the 
fine collection of J. Buchanan, Esq., Oswald Road, Morningside, Edinburgh. 
Dendrobium Hillii is an evergreen species with cylindrical jointed stems, 
eighteen or more inches in length, bearing several short dark green leaves. The 
racemes of flowers proceed from the upper part of the matured stems, and grow to 
the length of twelve or more inches; the flowers are cream-coloured, the lip being 
slightly spotted with purple. It flowers during the winter months, and lasts several
