A very distinct species allied to P. Volucris, Sw., having the 
suberect anther of that species with the gland situated below, but 
readily distinguished by the larger leaves and flowers and the 
differently shaped parts of the lip. 
The curious free lobes, which cover the glands but can very easily 
be pushed aside, are very similar to those which are described in 
P. Volucris as being at the base of the limb of the lip. In 
P. MacLoughlinii, however, the lobes appeared clearly to be on the 
rostellum and to arise from near the stigmas. Plate XVII. 
Geissorhiza Patersoniae, L. Bolus ( Irideae-Ixieae ) habitu robustiore, peri- 
anthii segmentis acuminatis, dilute lilacinis, seminibus late alatis, 
distinguitur. 
Cormus globosus vel globose ovoideus, 0'8 — 1‘2 cm. diam. ; caulis 
flexuosus vel rarius strictus, in genere, subrobustus, ad 02 cm. diam., 
cum ceteris partibus glaberrimus, ad 47 cm. altus ; folia 4 — 6, erecta, 
inferiora approximata, superiora distantia, plus minusve reducta, 
vaginantia, vaginis nervosis, laminis anguste linearibus acuminatis 
uninerviis, ad 34 cm. longa, OT — 0'2 cm. lata; spica simplex vel e folio 
supremo furcata, laxiuscule 2 — 10 fl., floribus equilateralibus ; spathae 
valva inferior oblonga herbacea, angustissime membranaceo-marginata, 
basi tantum viridis, superne subpurpurea, 1 — 17 cm. longa, superior 
apice bidentata vel biloba, apicem infra viridis, O' 9 — 1'5 cm. longa; 
perianthium 2 — 2 - 6 cm. longum, tubo 0'4 — 0'6 cm. longo, segmentis 
lanceolatis vel ovato-lanceolatis, acuminatis, pagina superiore dilute 
lilacina, purpureovittatis, pagina inferiore glaucis ; stamina parum 
ultra perianthii dimidium attingentia, antheris 0'4 — 0 5 cm. longis ; 
ovarium 0'4 cm. longum ; stylum evolutum 0'9 cm. longum, ramis 
fere ter longius ; capsula oblonga, basi apiceque parum angustata, 
ad IT cm. longa, 0'4 cm. diam., seminibus subglobosis, late alatis. 
Cape Province : South-Western Region; Riversdale Div., J. Muir, 
1050 ; in clay soil on stony hillsides nr. Riversdale, alt. 850 ft., fl. Oct., 
H. Bolus, 11,385; N. S. Pillans. Uitenhage Div., Redhouse, fl. Sept., 
Florence Paterson, 47 ; nr. Port Elizabeth, fl. Sept., E. Kensit, 2. 
Distinguished by the rather robust habit, acuminate pale lilac 
perianth-segments, and broadly winged seeds. This species is in- 
teresting as showing some affinity to Gladiolus, which the specimens 
in the dried state somewhat resemble. Living material, however, 
exhibits the regular perianth and equilateral stamens characteristic of 
Geissorhiza. 
Gladiolus Muirii, L. Bolus ( Irideae-Ixieae ). G. tenui affinis, sed foliis 4 — 6, 
tubo perianthii breviore, segmentis exterioribus interioribus distincte 
longioribus, differt.
