` THE RACEMOSE SOLENID. ] 
ring represents the series to which the perfect stamen belongs, and the 
inner ring the series which is usually more or less disguised. For the K 
convenience of description the perfect stamen and accompanying j 
abortions may be called the outer stamen and staminodes, while those / 
of the second and more paradoxical series may be termed the inner | 
stamen and staminodes. The asterisks indicate an entire suppression — | 
of staminodes.) * 
No. 1 shows the theoretical state of the flower, with the three outer ا‎ 
stamens complete, and three inner staminodes. The outer stamens are ba 
here in the condition in which they appear in the plant figured by Dr. 
Wight under the name of Euproboscis, and by Griffith in Falconer’s 
Dendrobium normale. 
No. 2. represents such genera as Odontoglossum in which one outer 
stamen is perfect, the two outer staminodes in the form of the lateral 
plates of the crest of the disk ; then of the inner staminodes two form 
the wings of the column, and the other the midrib which separates or is T 
blended with the lateral plates of the disk. E e 
No. 8 represents such a structure as that of Anacamptis, where the 
usual outer stamen is attended by two of the inner staminodes, while 
two outer staminodes appear as plates on the lip, and the central of the 
inner staminodes is missing. Solenidium would also belong to this 
form. 
No. 4 is the case of Cymbidium properly so called, in which all the 
inner staminodes are deficient, and the lateral outer staminodes lie upon 
the lip in the form of two raised lines. 
No. 5 shows the beginning of the series in which outer lateral 
staminodes are wanting, except one which represents the perfect stamen 
in the preceding cases, while on the other hand the two lateral inner 
stamens are perfect and the third wanting ; this occurs in Cypripedium. : 
No. 6. In Orchis the structure is absolutely reduced to one perfect 
outer stamen and a pair of inner lateral staminodes, occurring as 
tubercles at the base of the column; all the other staminal apparatus & 
being missing. Thelymitra comes here. e 
No. 7 shows what happens in Zygostates in which the outer lateral 
staminodes are absent, but the whole of the inner ones are fully and 
largely developed. The structure of Pterostylis enters into the same 
category, although in some respects very different. 
No. 8 may be regarded as the expression of Maxillaria, with all the 
staminal apparatus gone except the usual outer stamen and the corre- 
sponding inner staminode in the form of a tumour on the lip. 
No. 9, with every part wanting except the outer central stamen, shows 
What the structure is of many Dendrobes, and Sarcopods.
