rigid leaves, by the acute calyx- segments, by the very short and broad 

 corolla-tube, v\-hich is hardly longer than the calyx, whereas in V. inacro- 

 carjM it is quite twice the length, and by the capsule not beuig more than 

 twice the length of the calyx-segments. As the name crassifoUa is 

 preoccupied by a European species, I have attached the name of its 

 zealous discoverer to the plant. 



It is worth mention that on the under-surface of the leaves, just 

 within the margin, there is a row of small pits, or " domatia," somewhat 

 similar to those which exist on the under-side of the various species of 

 Cojjrosma, where, however, they are found in the axils formed by the 

 junction of the main veins with the midrib. These pits appear to be 

 mhabited by small Acari, as in Goprosvia. 



4. Caladenia exigua Cheesem. sp. nov. 



G. minor Hook. f. affinis, sed differt caule minora et graciliore, sepalis 

 et petalis acuminatis, labelli lo'oo intermedio margine 1-glanduloso. 



Erectus, gracillimus, 8-15 cm. altus. Gaulis strictus, tenuis, glanduloso- 

 pilosus, basi unifoliatus. Folium parvum, anguste lineare, 2-6 cm. 

 longum, 1mm. latum, parce pilosum. Flores 1 aut raro 2, sepalo inter- 

 medio erecto, anguste lanceolato, acuminate ; lateralibus petalisque simili- 

 bus, patentibus vel deflexis ; labello lato, 3-lobo, disco glandulis 2-seriatis 

 stipitatis ornato; lobo intermedio margine 1-glanduloso. 



Hab. — North Island : Leptospermum scrub near Kaitaia, Mongonui 

 County ; R. H. Mattheivs and H. B. Mattheios ! 



Stems shorter and more slender and wiry than in C. minor, 2-5 in. 

 high, sparingly glandular-pilose. Leaf solitary from the base of the stem, 

 small, very narrow linear, f- 2-|- in. long, broad, very sparingly pilose or 

 almost glabrate. Flowers seldom more than one ; sepals and petals 

 subequai, all narrow-lanceolate and acuminate, upper sepal erect, the rest 

 spreadmg or defiexed. Lip broad, 3-lobed ; disc with two continuous 

 rows of bright-yellow stipitate glands as in G. minor; intermediate lobe 

 with only one marginal stipitate gland on each side ; lateral lobes with 

 transverse purplish bands. 



Since I published this in the Manual as var. exigua of G. ininor I have 

 been supplied by Mr. H. B. Matthews with an extensive series of both 

 fresh and dried specimens of the various Galadcniae found near Kaitaia. 

 Mr. Matthews has always contended for the specific distinctness of 

 G. exigua, and his specimens prove that the differences are constant, and 

 are also accompanied by a difference in the flowering season, G. exigua 

 flowering at Kaitaia from the 10th September to the 25th September, while 

 G. minor blooms during October and the early part of November. 1 

 accept G. exigua, therefore, as differing from G. minor in its much smaller 

 size and more slender habit ; in the smaller flowers ; in the sepals and 

 petals being narrow-lanceolate and acuminate, instead of linear and 

 obtuse as in G. minor ; and in the middle lobe of the lip having only one 

 stipitate gland on each side, whereas G. viinor has several.
