Species novas in Gardener's Chronicle, 3. ser., XLI1 (1907). 357 



This is a half-sister, upon the side of the male parent, to Odonto- 

 glossum X Astraea, described in the issue for July 20, 1907, p. 42. The 

 sepals are clear yellow, having a small brown blotch at two-thirds distance 

 from their bases. The petals are coloured similarly, slightly lighter 

 towards the bases, having a couple of spots in the same position as 

 that in the sepals. All five segments are otherwise unspotted. 



The lip is lighter in tint, having a broad transverse brown blotch 

 on the yellow, just above the crest, where 0. nobile is always spotted; 

 its shoulders and channel have small spots and a brown marginal line, 

 which are often present in the female parent. The crest is like that of 

 0. Lindleyanum, slightly more filamentous than in 0. X Astraea. The 

 adnation of lip to column plainly shows the influence of 0. Lindleyanum, 

 the reniform blade giving evidence of 0. nobile. 



The column is short and a little up-curved, as in 0. nobile, nearly 

 white, the wings being almost as in 0. Lindleyanum and slightly spotted. 

 Anther cap light yellow. 



This plant is only small, and bore two flowers. It is one of a series 

 of crosses I made with the same male parent, and, compared to 0. 

 X Astraea, clearly shows the influence of 0. nobile against that of O. 

 X Fascinator, and, through it, that of 0. crispum. Reversion in this case 

 produces the form of 0. Lindleyanum, with loss of spotting of the male 

 parent; the white of 0. nobile assuming the yellow ground colour of 0. 

 Waltianum. 



70. Eria rhyncostyloides J. O'Brien, 1. c, p. 370. 



Roots wiry, dark-coloured, pseudo-bulbs clustered, green in the joung 

 state, brown with silvery covering when mature, ovoid, compressed, 

 showing deep openings whene the old flower-spikes had been, 3 to 4 

 inches in height, 2 inches wide; leaves 3 to 4, 12 to 18 inches long, 

 2 inches wide, thick in texture, bright green. Inflorescence from the 

 upper part of the pseudo-bulb 8 inches in length; rachis stout, slightly 

 tomentose, the basal 2 inches naked, the rest bearing an equally-arranged 

 cylindrical spike of 250 to 300 flowers. Pedicels and ovaries two-thirds 

 of an inch, and having at the base of each an ovate acuminate, slightly 

 concave reflexed, whitish-green bract. Flowers half an inch across; 

 sepals ovate acuminate; mentum broad, obtuse; petals narrower than the 

 sepals, lanceolate. Labellum obscurely trilobed, orbicular, concave at the 

 base, which is tinged with rose colour, front acuminate. Column short, 

 tinged with purple at the apex; anther cap brownish red. The flowers 

 are white with a slight blush tint, the labellum with rosetinted base. 

 The surface of the flower has a granulated, or frosted, appearance, and 

 the ovaries and backs of the sepals are sparsely tomentose. 



Java. 



In structure the individual flower approaches most nearly to Eria 

 convallarioides. The plant, however, is much larger than that of E. con- 

 vaUarioides, more fleshy in all its parts, and it bears a slight resemblance 

 to that of the wellknown Bhyncostylis retusa (Saccolabium guttatum) in the 

 general appearance of its dense inflorescence.
