acquired by Lord Rothschild. None of them could be induced to 

 flower till September^ 1882, but since that date the flowering of 

 Vanda Hooheriana has been an annual occurrence at Tring. 



In Borneo, Vanda Hoolieriana is epiphytal, often growing on a 



slender-stemmed species of Pandanus above the water or mud fully 



exposed to the blazing sun. It has since been discovered in the 



district of Kinta, in Perak, in a long valley formed by ranges of 



limestone hills, and watered by the Perak River, by Major Frowd 



Walker, who has communicated the following particulars of its habitat 



to The Garden,^ through Mr. B. D. Knox, of Caversham, Reading : — ■ 



" The district is thickly studded with marsh ; these marshes are full 



of thick low jungle not more than 5 feet high, quite or almost destitute 



of forest, and therefore exposed to the full rays of the sun. In some 



of these marshes Vanda Hooheriana is found creeping over the jungle 



growth ; the stems rest on the top of the bushes, and the aerial roots 



cling to them. The flowers are always seen on the top of the bushes in 



the blazing sun, and are produced all the year round. So common is 



this flower in the district that it is called the ' Kinta weed.' The 



observed temperature in Kinta during the year 1889 ranged from 18° — 



36° C. (64°— 97° F.), and the rainfall exceeded 150 inches." 



Cultural Note. — At Tring Park Vanda Hooheriana is cultivated in a 

 house almost entirely devoted to the allied V. teres, and which we have 

 described in the cultural note relating to that species. For V. Hooheriana 

 pots 6 inches in diameter at the rim are preferred ; the pots are filled 

 with a mixture of broken crocks and charcoal, and surfaced with 

 sphagnum moss that is kept constantly saturated. The plants, about 

 four in number to each pot, are affixed by means of copper wire to a 

 piece of board 15 — 18 inches long, 6 inches broad at top, and about 

 \ inch tliick ; the boards with the plants so affixed to them are plunged 

 to the bottom of the pots, so that the lower part of the stems is buried 

 in the mixture of crocks and charcoal. The treatment as regards 

 temperature, watering, etc., is the same as for V. teres, and is given in 

 detail under that species. 



V. insignis 



Leaves 9 — 12 inches long, and about an inch broad, obliquely incised 

 and toothed at the apex, strongly keeled beneath. Kacemes scarcely 

 longer than the leaves, 4 — 7 flowered. Flowers 2 — 2| inches in diameter, 

 on white, twisted, grooved pedicels ; sepals and petals obovate-spathulate, 

 bright tawny yellow with dark brown oblong spots that are confluent 

 at the margins and apex ; lip sub-pandurate, Avith two short white basal
