 Spae Mon,, 14 ; Flore des Sen-es, t. 283-4, — L. Jama-juri, Siebold et 

 De Vriese, Tuinbow Flora, i., 819, t. 11. — L. Eximium Wilsoni, ^ort.

 8 or 9 inches long. — L. Talicsima and L. Ahchasiciun, Hort., are formS' 

 of Lonrjifonim. 



i.s dilated at tlie .spot where the lolies hegin, and in conserjiieni>e of tliis aiTangement the- 

 flower i.s moderately open. The flower oi Lonrjiflorum enlarges gradually ami regularly 

 from below upwards. The flower is more open than in Takcsinia, and shorter, and its- 

 six divisions are more widely spreading, the three outer ones are even appreciably 

 revolute. In £.ri-,niuui the tube is more nearly cylindrical, throughout its length ;: 

 the aperture of the flower is oblique, and its six divisions are longer, naiTower, 

 thinner, and completely revolute The dimensions of the flowers also serve to 

 characterise the varieties. The flower of Loncjiflorum Takcsima is 165 millimetres- 

 (6J inches, about) in length, while the tube of the flower from the base to the 

 origin of the lobes measures 95 millimetres (nearh' 4 inches). The flower of 

 Longiflorum (var. Grandiflorum, and hence larger than in the ty\>e) measures- 

 140 millimetres in length = about 5-j inches, of which the tube from the ba.se to the 

 origin of the lobe measures about half (2;^ inches) ; nevertheless, the diameter of the 

 flower from tip to tip of the lobes is appreciably wider than in Lonrjifiorum. Talccsima. 

 La.stly, the flower of E.dmium has a total length of 180 millimetres (more than 7 inches), 

 of which 100 (4^ inches, about) are taken up by the tube. j\I. Lemaire has remarked 

 ("Flore des Serres," iii., ]il. 282, 284) that the lilaments of the stamens are of unequal 

 length in Eximium, while they are equal in Loiigifiorum, as they are also, according to- 

 ll. Duchartre's experience, in Longiflorum Takcsima. 



To sum uji, Eximium is characterised by its horizontal flower, which is longest of the- 

 three ; by its narrow tube, but slightly dilated above; its wide and oblique limb, its 

 oblong revolute lobes, and its tuiei^ual filaments. 



Longiflorum has its flowers pdaced obliqueh' on the stalk, and almost erect ; its- 

 flower is the shortest and the most widely expanded of the three ; its lobes are wide, the 

 three outer ones appreciably revolute. 



Longiflorum Takcsima has the flower obli(iuely inserted on the stalk, Init less so- 

 than in the case of the last mentioned, intermediate in absolute length between the two 

 others, the lea.st widely expanded of the three, manifestly dilated at the throat, more or 

 less tinged with violet externally, and with wide spreading (not revolute) lobes. As- 

 to the stem and leaves of these plants, the ditt'erences are so slight that no useful 

 characters can be obtained from them. Nevertheless, it may be remarked that the leaves- 

 oi Longiflorum arc broader, shorter, and thicker, a-nd more fleshy than those of the other 

 tvjo ; while those of Takcsima are the longest and naiTowest, and usually 3-nerved. 



M. Duchartre was originally of opinion that Eximium was a distinct sjiecies, but 

 he no longer holds that view with the same confidence, and, moreover, he considers the- 

 two other forms as varieties of one species. Eximium has a .strong and agreeable- 

 perfume, like that of orange blo.ssom, and according to ^I. Leichtlin it may be dis- 

 tinguished from all the varieties of Longiflorum by its more compact habit (.') its shorter, 

 more nearly sesile leaves (?), and generally by the great size of its snow-white flowers, 

 (nearly 8 inches long). — Baker. 



Having for some years past been familiar with all these varieties of the Longiflor^im 

 group, we diflerentiatc them as follows. 



Philippinciise, with tall slender stem, foliage narrow, frequent and 

 acutely pointed, perianth 8 inches long, externally green tinted, tube 

 long, fuimel-shaped ; ilisc broad, widely expanded, highly revolute p 

 habit slender, flower laige. 



Takcsima, {.lama-juii of Siebold), dwarf habit, foliage broad, 

 perianth chocolate tinted externally, 5 — 6 inches long, tube bell-shaped, 

 L disc expanded, slightly revolute.
