42 COELOGYNE RUMPHII Linril. Fol. L n. 36: 



Angraecum nervosum. Rumph. Herb. Amb.. VF. t. 48. 

 Wild in Amboyna ; on trees Rumphius. — I only know this from ihe above flgure 

 It is evidently very near C. bilamellata and longifolia, to the iatter of which Blume 

 refers it. But it bears a broad ribbed ieaf tw.elve or flfteen inches long by four wide 

 and the raceraes are only three or fonr - flowercd. It is nearest C. bilamellata , but 

 its flowers are four times as large. resembling a flying hornet, according lo Rumphius. 

 who states ihem to be yellowish white outside, and variegated wilh brown in the inside. 



§ 3. PLEIONE. Don. Prodr. Nep., 37. — Gomphostylis, Wallich. 



There is someihing so peculiar in the plants called Pleione by Don, that it would 

 be desirable to flnd some means of separaiing ihem from Coelogyne. Occasionally I have 

 imagined , that they might be defined by such characlers as a saccate lip. an undivided 

 lip furnished by bearded not lameilate veins , or by the divisions of the flower tapering 

 to the base instead of being obluse. But the last peculiarity, on which I had most relied 

 is so enlirely set aside by C. Hookeriana , which has ihe form of C. cristata, thai after 

 all I find it necessary to leave them as an Alpine form of Coelogyne. in the hope that 

 future observers will discover sonie sound generic characler. All ihe species are Alpine, 

 Dr. Royle describes ihe P. praecox as being found ornameniing with its large, richly- 

 coloured flowers ihe branches of Oaks on Louriour, at 7500 feet of elevation, in 30° N. 

 Lat. , but only during ihe moisture of ihe rainy season. The secret of their successful 

 cultivation in England lies in keeping ihem cool and dry while at rest, and forcing them 

 wilh heat, moisture and bright light as long as they are inclined to grow. 



43. COELOGYNE HOOKERIANA Lindl. Fol, l. n. 37: 



C. pseudobulbis ovatis glabris, foliis synanthiis oblongi? scapo longio- 

 ribus vaginis laevibus, bractea ovario breviore, sepalis petalisque ereclis 

 oblongis acutis, labello transverso rhoraboideo retuso basi circulari serralo 

 venis 7 villosis, clinandrio cunealo. 



Wild in Sikkim-Himalaya; Darjeeling, on rocks in woods at 7— 10.000 feet J. D' Hooker 

 (v. s. sp. comm. cel. invent. et ic. pict.) — A preity liltle plant, about four inches 

 high, with almost ihe habit of Cypripedium gultatum. Flower move than an inch and 

 a half long. wiih bright rose-coloured sepals and petals, and a whiie lip tinged or 

 daggled wiih pink. The lip is not uniied to the column in any degree, ihe parts of 

 ihe flower do not taper to the base , and ihe leaves and flowers all appear al ihe same 

 time , in which circumstances ihis differs from olher Fleiones, 



44. COELOGYNE DIPHYLLA Lindl. Fol. I. n. 38: 



C. pseudobulbis oblongis medio constrictis, foliis geminis angustis 

 subcoriaceis acuminatis, pedunculo flore ter longiore, bractea obtusa 

 inflata apiculata ovarii longitudine, labello obtuse trilobo emarginato 

 venis fimbriatis 5—7 inlerruptis altera brevi adjecta utrinque juxta apicem. 



Pleione diphylla. Lindley, in Paxton's FI. Gard.. sub l. 51. 

 Wild in Khasia Griffith (v. s. sp. comm. beat. invent.) — I have specimens offhis plant 

 from Mr. Griffiih . who found it on ihe Khasia Mountains , in shaded rocky places at 

 Churra: and whose memorandum appears in his itinerary Notes , p. 44. Nr. 684. Frora 

 this It appears ihat ihe leaves are somewhat coriaceous , and grow in pairs on the 

 summit of oblong [iseudobulbs. contracted in ihe middle , and spoited wiih purple on 

 a green ground. The flowers are said lo be very handsome , and white ; ihe lip being 

 siained and lined inside wilh violet and crimson, and decorated with from seven to 

 nine lines of yellow fringes.
